Good

There was difficulty with my connecting flight due to inconsistent COVID regulations. I was almost not allowed on, despite fulfilling all my requirements for my destination country. I was over-billed by Alaska Airlines for my luggage as well.

A to Z on this flight was just great!

Pros: "Singapore Airlines has everything worked out for you before you land. That's a great help. The stewardesses were just phenomenal and endlessly polite. I will definitely use them again."
Cons: "As much as I normally nitpick something, I literally have no criticism at all of Singapore Airlines. Everything they did was a step above everyone else."
Pros: "Crew very polite and friendly"
Cons: "Crew forgot to bring me things twice so I had to ask another crew member on both occasions."
Cons: "Rather long wait at business check-in, friendliness there ok, on board service slow with the champagne, old aircraft with old configuration of seats, nothing really bad, but it's not like this that you win an airline of the year award!"
Pros: "Nothing special."
Cons: "Meal was disappointing. Beef was overcook and hard. Service quality is just okay."
Cons: "On time would be better."
Pros: "Newer Aircraft and very convenient"
Cons: "I dont see any thing to improve"
Cons: "NA"
Pros: "Amazing services and foods"
Cons: "The business class seat was great"
Cons: "Nothing comment."
Cons: "I think the food in our flight was not that good.."
Cons: "For business class SQ, the crew service was severely sub-par. Seat arrangement same as in bigger 777, so actual space is much shorter and therefore uncomfortable for sleeping and lounging."
Pros: "I like all"
Cons: "Nothing"
Pros: "Everything. New plane amazing food on a two hour flight Great new entertainment system on the seat back."
Cons: "A little more leg room."
Pros: "Seats were good"
Cons: "Food could have been better"
Cons: "We had to go through security after coming in from international and I went through a biometric scanner which I’ve done 100’s of Times I was very unnecessarily felt up for 10 minutes. I had shorts and a T-shirt on, and was pretty sure after the 1st round of groping that there was nothing there"
Pros: "Excellent service"
Cons: "More tasty snacks throughout the flight"
Pros: "The inflight entertainment was great, lots of movie selections"
Cons: "The leg room was horrible. Honestly the worst space I've ever had in a flight. I was shocked considering Singapore air is considered one of the best airlines"
Pros: "The cabin crew were fantastic. Food was abundant. Most boarding systems worked well. Choosing seats was confusing on website so we were allocated seating. The newer planes had a fantastic touch screen entertainment system. The seats on the newer planes were much more comfortable and roomy"
Cons: "The small seats are squishy on the older planes. The entertainment system on the older planes were dated and difficult to use. I felt sick after the flight to UK but felt fine coming home after one long flight on a newer plane."
Pros: "Singapore Airlines delivers as always. Friendly crew and clean and well maintained aircraft."
Pros: "Food, service"
Pros: "SIA service and food is always good. The flight went by quickly which is good."
Cons: "The entertainment system for the 777 did not have a touchscreen which I have been accustomed to on other SIA flights, but the main issue was the brightest setting for the screen was very dim. I think the screen is just old and not as bright as before."
Pros: "Friendly staff."
Cons: "The food for Premium Economy was very poor. The choices were substandard and the food at some meals was inedible. Very disappointing for the price of the tickets. The cabins and equipment seemed old and jaded."
Pros: "Very attentive and super awesome crew."
Cons: "Nothing"
Cons: "The desserts. The bun."
Pros: "Excellent attention to service and comfort."
Pros: "Efficient, comfortable."
Cons: "Delayed 2 hours behind schedule"

Pros: "The food is very good in economy. Large screen tv gor movies and games."
Cons: "all was good, nothing bad"

Cons: "Nothing to mention, all was good"
Pros: "The cabin crew are very helpful and friendly. I sat at the end of the row in the upper deck. After the gate door closed , they let me sit in the empty sit away from the toilets . During the flight they’re around with water and juices to make sure we’re dehydrated,"
Pros: "everything are okey"
Pros: "Great service always"
Pros: "Wonderful and warm crew made me feel at home. Loads of entertainment but best of all, comfortable seat/bed allowed for a goodnight's sleep!"

Cons: "Really nothing. I loved flying with them."
Pros: "Great flight amazing service"
Pros: "Professionalism and friendliness of crew"
Cons: "Seat not great for my length even though it was business class"
Pros: "As usual, plane is in good shape and crew are well trained. Nothing wrong with all the basics, but Singapore Air has definitely lost its lustre."
Cons: "For heaven's sake, please don't announce a boarding procedure and then not follow it. If you want to have a free-for-all rugby scrum to get on the plane, so be it. But don't announce boarding by rows/groups and then not make even a lame attempt to adhere to it."
Pros: "Crew was very attentive and professional"
Cons: "Return flight the movies were the same as three weeks earlier."
Pros: "I am still trying to find my bags. I missed my connection and Jet Blue made me stand in a line to get rebooked for 7 hours. Unprofessional, uncaring. None of this was my fault but everyone who represents Jet Blue treated me as if it were. Never again"
Cons: "The video screens need to be upgraded"
Pros: "Check in and boarding were flawless. The flight left about one hour late. The seats in coach are getting smaller and smaller. I got an aisle seat to have a little extra room (I'm 6'1") only to get hit big time by the food cart (they did apologize). The food was plentiful, but mediocre at best. The flight attendants were working hard, but we're abrupt and tired. Overall, I have three stars, when in the past, flying SA was always a five star experience. It got me back home though. :)"
Pros: "The crew was friendly and helpful."
Cons: "The leg room was smaller than most other flights and the war phonejack didn't work and the video constantly paused every 30 seconds. Also the 1 8kilo bad allowance in the cabin is a bit unreasonable but I see why they need to because the overhead storage and under the sit storage was less than normal too."
Pros: "Very comfortable overall"
Cons: "Unrelated to the flight, the ground handling staff at Istanbul airport, especially the information desk, should be given a crash course in customer care."
Pros: "Excellent crew"
Cons: "Flight delayed and no reason Food very bad"
Pros: "Comfortable for that sort of journey"
Cons: "N/a"
Cons: "Everything is Good."
Cons: "My bags were misplaced I have to wait for an extra day to get it"

Cons: "2 hours delayed"
Pros: "Food and service in business class were splendid."
Cons: "Absolutely nothing"

Pros: "Food"
Pros: "The food was quite good"
Cons: "The new type of aircraft - less room between seats, entertainment system was poor, online check in didn't work, when I got to the airport I was sent away for an hour - was unable to get my prefered seat (window) by the time I had returned."
Pros: "Rapidly becoming my airline of choice. Great service, comfortable and on time. Relatively new fleet and not cramped. Puts other national carriers (including BA) to shame"
Pros: "Food"
Cons: "Good food"
Pros: "Infinitely superior to BA on the London to Istanbul route , in economy but especially so in business. Great entertainment whilst BA have non. Also full service meals in economy whereas BA make you pay on boatd"
Pros: "Business class cabin in the 777 was really spacious. Flight wasn’t full so I also had two seats to myself. Onboard chef was a beautiful touch and food was also delicious. Seats comfortable and IFE good."
Cons: "Heathrow T2 Business class checkin wasn’t clearly signed from entrance. If someone was next to me I would not have enjoyed not having aisle access. Water should be served more regularly without having to ask."
Pros: "Food was great."
Cons: "Long waits, poor communication, either too warm or too cold"
Pros: "Airplane crew was amazingly friendly and helpful"
Pros: "Good"
Cons: "No space"

Pros: "Comfort"
Cons: "Ordered veggie meal didn't turn up!"

Cons: "The food is dry like rice and beef is dry and the the pasta is too plain, just pasta and some blended tomatoes is not balanced"
Pros: "Great food! Loved that you get a menu to choose from"
Cons: "We were not asked or given the option to choose our seats on the plane."
Cons: "Staff at Business Class checkin walking off the desk when we tried to check in. The on-line check failed and that was the only reason to go to the counter, but, alas, it then took an hour to get things sorted because the single staff person just walked off because no one was there to relieve her."
Pros: "Flight attendants need to be friendly."
Cons: "I will never use Turkish airlines again."
Pros: "Nothing."
Cons: "The fact that I missed my connection flight in Thailand because of a two hour delay. I was never informed why there was so much of a delay and in turn I had to pay triple of what I payed before for my flight. Very disappointed. Won't be flying this airline again. Service was rude. They should be more responsible when it comes to timing. We were on the flight waiting for two hours!!!"
Pros: "Great crew. Super nice to our 4 year old daughter. They were quick, extra polite and efficient. I'm usually quite picky but this leg was perfect."
Cons: "It was all good(which I rarely get to say these days on any carrier)"
Pros: "Very good customer service and entertainment"
Pros: "Our flight was cancelled and they gave us direct flight back to Singapore in premium economy seats."
Cons: "This is our second experience of flights being cancelled via Turkish Airlines. Very disappointing customer care when flights get cancelled. Staff totally unprepared and untrained for such situations. We waited around for 6 hours before finding out on our own, that the flight was cancelled. The notice was not shown on the board. In all waited around at the airport for more than 10 hours before we were finally carted off to a small hotel near by at 1230am in the morning. Very little to no information given throughout the whole process, stranded with parched throats, no luggage, clean clothes or toothbrush."
Pros: "Everything"
Pros: "Efficiency and customer service"
Cons: "I didn't get s pre ordered kosher meal on 2 nd leg of my flight"
Pros: "food is always good..crew too"
Cons: "less and less space in economy class for passengers not very kind boaridng people no info on posibble complimentary upgrade for Gold Card passengers"
Pros: "Better food and service than other airlines on which I've traveled recently. Loading passengers was disciplined and speedy. Staff very helpful. Istanbul airport is great for a long wait. If you go to a gate waiting area with no flight soon, you can stretch out and sleep. Good English-language bookstore."
Pros: "Crew are always available and helpful"
Cons: "Food was dreadful. I thought I had chosen a seat online, but discovered I was in a middle seat. Having 3 seats on the sides makes it very difficult for the window seat occupant to maneuver."
Pros: "The entertainment specially the Turkish airline safety part"
Cons: "for short trip no need for mugabelat before food"
Pros: "Everything, it's just straightforward and good, the only thing I don't like it's no direct flights from my local airport, but if I have to go via Istanbul then Turkish airlines it's my preferred carrier."
Pros: "Boarding was on time, the crew was helpful."
Cons: "The entertaintment screen at my seat wasn't able to play videos. The comfort would be excellent if there would be a foot support."
Pros: "This is a government run airline with very poor customer service. I flew 6 flights in December, 2016 in business class - out of which 5 flights were late. There was no help at the transfer desk in Istanbul to get onto another flight as my connecting flight was missed because the original outbound flight was late. The customer service staff both at the lounge and the transfer desk were inept and rude and did not want to help. I shudder to think how economy passengers are treated."
Cons: "1) No organized boarding process - there is a general melee at the boarding gate with a lot of shoving and pushing. 2) Customer service staff are rude, incompetent and unhelpful 3) No recognition that customers are to be served 4) Food selection in business class was mediocre and poor 5) Old aircraft - on flight from Istanbul to London, business class was 3 abreast with the middle seat being used as a tray table. 6) Sleeper class is mediocre - seat width is poor and one cannot even turn on the side"
Pros: "Turkish crew members are usually very friendly."
Pros: "Food, entertainment, crew"
Pros: "Service from the flight attendants were fantastic. The food was delicious and the entertainment included plenty of movie options. I'm also glad that my bags were never lost throughout all of my flights this summer on Turkish Airlines."
Cons: "I know seats in the 777-300 recline but do not disrupt the next row's space. That was not the case on the Airbus A330-300. It would be nice if the same seats were on the Airbus aircraft I flew from Istanbul to Bangkok."
Pros: "Nothing!"
Cons: "15 hour stop over in Istanbul with the rudest, prejudiced airport staff ever!!!"
Pros: "They answered the phone quickly."
Cons: "I wanted to cancel my flight on Turkish as I was concerned about safety after the terrible attack there at IST. I was told that TK were changing tickets and issuing refunds for a period of 7 days after the attack - and I was scheduled to fly on day 8. They refused to refund or change - all they would say are 'fare fules' - 'fare rules'. When I passenger has a concern over personal safety, and in the aftermath of a large scale lapse in security at their main hub, they should be more understanding and not stand by their arbitrary 7 day rule."
Cons: "The flight tracker was the only thing we could watch on this flight."
Pros: "One of the best flight experiences I have had in a long time."
Pros: "The crew is excellent"
Cons: "The seats area are too small my knees hurt as they hit just the edge of the food tray, impossible flight with the seat other than straight as you will be disturbing a lot the other passengers, although unfortunately some people do not care about the confort of the others"
Pros: "It was on one of their newer planes which meant that we had decent comfort and entertainment!"
Cons: "The seats were staggered between the middle and sides, so my family was eventually split across two rows. I hadn't expected that."
Pros: "This is a great way to travel from Helsinki to Tampere and avoid the railway and train changing."
Cons: "The plane is not comfortable, but the flight is very short. It balances out."
Pros: "All good, especiallly cabin crew who appear to actually enjoy their jobs and interacting with passenger (unlike some supposedly premium carriers)."
Cons: "All good, especiallly cabin crew who appear to actually enjoy their jobs and interacting with passenger (unlike some supposedly premium carriers)."
Pros: "All good. Very hospitable cabin crew, great service."
Cons: "Nothing."
Pros: "Customer service and efficiency"
Cons: "The delay because of a software glitch"
Pros: "The blueberry juice was good!!"
Cons: "Sitting by the bathrooms. There weren’t even pretzels."
Pros: "Flew on new A350, liked the seat TV, live map/camera. Good selection of entertainment."
Cons: "Website is very poor and ended up making booking through call centre and paying double what website was offering. Food & drink is expensive. In flight wi-fi expensive."
Pros: "Beautiful new modern aircraft & plenty of spare seats on the flight. Paid for Economy comfort & it was worth it."
Cons: "Did not like that you had to pay for drinks & snacks. For someone of Finnair’s standing, you would think they would include it."
Pros: "The new Airbus A350"
Cons: "Onboard food and drink is quite expensive"
Pros: "Far better quality and value than BA, it's OneWorld partner."
Cons: "It was all good."
Pros: "We were kept informed about the delay"
Cons: "Has to wait 14 hours in Helsinki for a 25 minute connecting flight"
Pros: "The staff were thoughtful and kind. They checked on us and offered snacks and water very regularly. My favorite, though, was that the captain took the time to alert us to the sights out the window. We had closed the shades at the request of the attendants and would have missed the beauty of Greenland had he not alerted us to peak out. I appreciate that!"
Pros: "Nice crew"
Cons: "old plane, not clean, flight delayed not airlines fault"
Cons: "Not enough leg room."
Pros: "Comfortable smooth flight, quiet in the large modern BA A380 aircraft"
Cons: "Usual boarding with people in rear having to get past people in lower row numbers having been boarded first."
Cons: "Whoever designed and built this airplane should literally be INDICTED - AND I AM NOT KIDDING! We were in disbelief the moment we boarded and saw the airplane. 10 people across jammed into the row??!! - and on an long international flight?? - are you kidding??!! Further, these were the SMALLEST seats I have EVER been forced to sit in. Neither I, or my friend came close to fitting. We literally had to alternate getting up and standing because we were literally overlapping each other when we sat! (His shoulder and arm were literally on top of me!!). It was so bad that when the stewardess came rolling down the aisle with her cart, I had to be aware and see her in advance so I could literally TURN MY BODY OVER TO THE LEFT HALF ON TOP OF THE PERSON SITTING NEXT TO ME SO SHE WOULDN'T TAKE OFF MY ARM AND SHOULDER. ULTIMATELY, SOMEONE, OR MORE THAN ONE PERSON, IS GOING TO GET SERIOUSLY HURT BY THIS RECKLESS, GREED-DRIVEN DESIGN!! The OVERT GREED by the airline (American) clearly reflected by this in trying to JAM as many human beings into a flight as possible like Sardines is DISGUSTING!!! You simply DO NOT TREAT HUMAN BEINGS THIS WAY!! It is also clear evidence that there needs to be tighter standards, regulations and penalties by the FAA and what is allowed by airlines. AND I AM SENDING A LETTER TO THE FAA!!!"
Pros: "The crew did an excellent job definitely went beyond good service, I enjoyed the food and they came often offering drinks. It was probabky my first long flight I wasn't thirsty at all. Overall I was very happy with my trip hope thank you!"
Cons: "I got slightly cold at one point and wished the lights were I little lower but I understand why the weren't."
Pros: "Made up some of lost time from delayed departure"
Cons: "Seats cramped"
Pros: "This flight was co-shared by British airways. After our horrible flight from San Diego to London, we decided to upgrade our returning flight from London to San Diego to a economy plus premier. This time the plane seems newer and recently refurbished. The seat can recline more, with lump bar support and nice foot/leg rest. It has a bit more legroom. The cabin is nice and new with large view touchscreen TV for each seat. Gluten free meal was good, I'm just glad they finally boarded the plane with my GF meal (after repeated unsuccessful attempts). The service was great, our BA attendants were polite and attentive."
Pros: "The flight to and from Los Angeles was operated by British Airways and was on one of their Airbus fleet. Boarding was completed efficiently and with ease. I sat on the upper deck and was very comfortable in comparison to other major airlines previously used for this particular flight. The plane was very clean and the crew were outstanding. Nothing appeared to be too much trouble for crew, and they were ready with beverages, including tea and coffee, and snacks throughout the flight. In flight entertainment was good. All in all very pleasant flight to and from the U K."
Pros: "Great flight and nice people"
Cons: "Because the flight was through british airways, extra baggage was $90 much more expensive than Finnair's prices. After paying that before departure to London I recieved an email from British Airways that stated an extra bag for both my flight to London and return flight to San Francisco had been fully paid for. At the airport I was told by British Airways employees that I would have to pay another $90 regardless of what my email said because their official prices are $90 each way not both. I showed them the confirmation I had recieved and all they could say was "that is confusing". There was very little empathy or attempt to help. As a result I was forced to leave the suitcase behind with my acquaintance in London and do an in airport shuffle of all of my belongings. The flight was great but beware emails that may not match up with online info."
Pros: "It was a British Airways flight, plane was large, and felt more roomy than what I'm used to. The service was impeccable."
Cons: "I booked this through Finnair and it was a British Airways code share .I was unable to get the record locator for BA and could not check in prior to getting to the airport ."
Pros: "Service was very good"
Pros: "Staff as always is polite"
Cons: "The man sitting next to me required two seats. The arm rested had to be lifted to my seat to accommodate him. I complained but the flight was full and my seat could not be changed. I was told that British Air policy was not to require extraordinary over weight people to buy two seats. No, instead the person next to that overweight person has to suffer. A very stupid and unfair policy. As a result I will never book Finnair or British Air again if I can avoid it."
Pros: "Polite and friendly flight attendants, smooth boarding procedure"
Cons: "Trash everywhere on the plan by mid flight.... Broken tv screen"
Cons: "We were unable to find a row of seats to more comfortably facilitate traveling with a baby and a toddler as seats that should have had a cot or extra seating didn't have the cot and were sold out for an additional fee before we had the chance to. Discussing this with the staff at check0in and at the gate, made no difference as they had no knowledge of what was available on that particular flight. Every time I fly with American I'm reminded of why I don't like the airline and I will do my best to avoid them moving forward regardless of competitive ticket pricing."
Pros: "Crew staff pleasant although did not particularly take the initiative to help customers."
Cons: "Boarding process at Heathrow was chaotic. Could not hear announcements and the response was a large crowd pushing towards an unclear entrance point. The seats are quite small and recline a minimal amount My biggest complaint is that four of us traveling together could not be seated in close proximity to each other, despite making that request over four months before the flight. Extremely frustrating to deal with check-in process as well--because we booked on Finnair, we could not use online system. This was an aggravation considering we were traveling. And--one of our bags was left behind in London. \"
Pros: "The new 777 airplanes were exceptional as well as the splendid airline crew!"
Cons: "Crew members were almost non-existent. Saw them beginning and end of flight only and this was not even red eye flight. Food quality was very poor for premium seating. Many on board had to approach flight crew in back of cabin to get something to drink throughout he 10 hour flight."
Pros: "Everything good except getting bag after flight."
Cons: "Took over an hour at baggage claim."
Cons: "The crew moved me to another seat on the return flight which allowed me entertainment but I hadThe entertainment console at my seat location on both flights to and from London did not work. That's 10 hours! to move away from my companions."
Pros: "The more modern plane with USB ports that actually charge and the higher quality and bigger displays really help make the trip more enjoyable."
Cons: "Not as much to eat on this BA flight back to Philidelphia from Hethrow as there was on the American Airlines flight there."
Pros: "Very relaxing, enjoyable flight. Entertainment was great with many different options to choose from (music, tv, movie, games). The plane was not full and I had the entire row to myself, making the flight that much more comfortable. Awesome crew that was attentive and friendly. Probably one of the best flights I've ever been on. Thanks!"
Pros: "Traveled BA and it was lovely, as usual."
Cons: "The flight staff on this particular BA flight was not as accommodating and friendly as I am so accustomed to on BA. Perhaps the flight attendant in charge of our seats was having a bad day. Also, the food on our BA flights to and from NYC was not up to scratch and rather bland and ordinary, compared to their usual. that was a huge disappointment."
Cons: "Food wasn't very good"
Pros: "That they actually gave a meal."
Cons: "Main course of chicken and rice was clearly on the small size for a 10+ hour flight. The chicken was in some vague sweet and sour sauce. It was a good thing that I had bought sandwiches before boarding. Return flight LHR to LAX was on BA and the main course of chicken and mashed potatoes was substantially larger and tastier."
Cons: "My Finnair flight from London to New York was cancelled due to weather conditions in New York. I understand that. What made me very frustrated and angry is that when I contacted Finnair to reschedule the flight I was told the flight was managed by British Airways and I would have to contact them When I contacted British Airways they said it was a Finnair flight and I had to contact them. I finally had no recourse but to buy another ticket through another airline. I feel that I should be reimbursed for my Finnair ticket from London to New York! I paid for a flight I never took. (The Finnair flight from New York to London was fine.)"
Cons: "Boarding was chaotic. Pre boading not enforced, all passengers boarding at the same."
Pros: "Although I booked this as Finnair, it was actually a British Airways flight, as I knew it would be. And it was fine--I don't think Finnair gets much credit, but whatever. I'd actually have liked to travel with someone more exotic!"
Pros: "Nothing"
Cons: "I booked this trip thinking it was with a European carrier - I had specifically wanted to avoid an American carrier. I was unable to confirm my flight online and had to ring because at NO POINT was I sent info that it was AA and not Finnair. I was charge almost $60 for this service because I did not have the right references sent with my confirmation email. T he seats were cramped and uncomfortable, I was unable to pick my seat on any flight and despite my request could not change it. Boarding at Chicago was a farce, none of the ground crew seemed to be in charge and we barely started boarding with 20 mins to takeoff. Needless to say the flight left late and we had to wait to take off, and of course had to wait to land in London."
Pros: "Arrived on time. Smooth flight."
Cons: "Nothing really."
Pros: "I took the bus back and forth from SF to London. Overseas I am now in contemplation of only flying British Airways from now on. The ride is comfortable, enjoyable, entertaining, adequate space, excellent service, food and drinks are the best I have had, and exceptional services and attention. This goes for both flights. I have been recommending Britsh Airways over the last several weeks to pretty much everyone I know. My family and I will be looking to British Airways for overseas flights as a priority."
Cons: "Connecting flight thru Heathrow was too close for comfort. I just reached the gate at the end of boarding. If there had been a glitch at all I would have missed the flight."
Pros: "British Airways operated this flight and it was a great experience. The seats were cramped, but almost to be expected for an economy service overseas."
Cons: "This is 2016 and to have planes that don't have in seat screens for entertainment is ridiculous. This was over a 9 hour flight. Won't choose your airline again because of this."
Pros: "The flight itself was very good. The food is descent and there are good selection of movies."
Cons: "My bag was left in London during my connection and arrived in Denver the next day. From what I understand once my bag arrived it was handed off to a third party delivery company. I am not sure how to complain to this company, maybe British Airways has a way to do it since they hired them. My bag must have arrived around 3:30pm in Denver. I got a text at 5pm that my bag was being delivered, which is fine so far. I did not hear before 10pm from the delivery guy about an estimated delivery time of my luggage, at that point he said he would show up around midnight. He eventually arrived at 3am. I don't know how the delivery company plans their deliveries but this is rather unacceptable. Unfortunately, this is not the first time this happens to me. Do they really always expect people to stay up until 3am the day after an international flight to get their luggage that was mis-handled by the airline.... I'd rather just drive to the airport myself the next day to get my suitcase myself."
Cons: "The headphone socket didn't work, the screen was tiny, the food was bordering on the inedible, the seating was cramped and uncomfortable, the air was dirty and unhealthy."
Pros: "Short good flight, with no issues. Friendly crew that were very professional."
Cons: "No complaints."
Pros: "I liked the crew and the fact that the flight was on time in both directions. We actually landed a little earlier than scheduled. The food was decent enough for airplane food and there were some recently released movies to watch."
Cons: "The seats were a bit cramped, which I guess is to be expected on a plane."
Pros: "We loved the service and staff. The plane was clean."
Cons: "The video/movie system was old, and the chairs were old."
