Pros: "Seats were comfortable"
Cons: "Please make an announcement to passengers to not be dismissive if their surroundings. Passenger in front of me was has no regard for people behind him. Kept throwing himself in seat aggressively which cause water/food on trail to fall over. Thanks"

Pros: "Wonderful on board service from the crew"

Pros: "comfortable seating, friendly helpful crew, good food"
Cons: "sometimes too cold sometimes too warm"

Cons: "You could have had my luggage arrive. Now I don’t know where it is"

Cons: "Delayed"

Cons: "The seat bottom was very uncomfortable and made my bum sore the rest of the day."

Cons: "Delayed flight."

Pros: "3 - 2 seat arrangement and lots of leg room. Excellent boarding."
Cons: "Bread of sandwich was dry."

Cons: "Guy behind me kept asking for a seat upgrade and when they didn’t oblige spent the whole 11hours kicking the back of my chair in protest. I understand this isn’t the crews’ fault. But maybe the bid upgrade for seats isn’t the best system?"

Pros: "It was a lovely easy flight, always lovely flying star alliance."
Cons: "Such a quick flight, everything was appropriate for that. Unsure exactly what would make it better"

Pros: "friendly and helpful crew"
Cons: "organise priority exit when we have a delayed arrival, so that those who have a train or flight connection can get out quicker"

Cons: "Seats were not too comfortable."

Cons: "Swiss precision"

Cons: "45mn late"

Cons: "Poor desk service Food at breakfast A joke"

Pros: "Really good flight. Clean,on time, efficient. Early arrival even"

Cons: "I was asked to check my carry-on. I have used this carry-on more than 50x without an issue. I have even put it in the smaller compartments on smaller Bombardier jets. I don't have an issue with being asked to check luggage, but I resent being asked when others are allowed to take their carry-on onto to the plane without issue. Right in front of me while I was waiting for a baggage tag, others were being checked in with carry-on equal to mine and allowed to take it onto the plane. I can only surmise that my ticket limited me to one bag onto the plane, although they would not tell me this. This was not clear when I booked the ticket nor when I checked in on-line. I had a 40 minute connection in Zurich so was very concerned that my luggage would not make it. Luckily, it did make it to my next stop. Swiss Air seems to have different restrictions than other airlines which I have encountered before. I take ownership that I should be aware of a tickets restrictions but this was a multi-leg trip (5). However, I will tend to avoid Swiss air in the future, to avoid having to research their unique restrictions."

Cons: "Two of the flight attrendants in our area were in a bad mood and it showed."

Cons: "It was delayed"

Pros: "It was very efficient and the staff was very nice. The line was long but fast. The seats have quite the lean which made it easier to lie back. Getting Swiss chocolate is always a plus."
Cons: "The seats weren’t as comfortable or fluffy but it was a short flight so it can very well be overseen."

Pros: "Nothing!! And by the way this is the last time I travel with you guys. I couldn’t travel because of my itinerary doula -Bruxelle - Zurich- Washington Dulles . I was not told when I bought the ticket that I will need a visa to transit between Bruxel to Zurich. Now they told me that my only option is to buy another ticket . Thank God éthiopien Airline was more affordable."
Cons: "Nothing!! And by the way this is the last time I travel with you guys. I couldn’t travel because of my itinerary doula -Bruxelle - Zurich- Washington Dulles . I was not told when I bought the ticket that I will need a visa to transit between Bruxel to Zurich. Now they told me that my only option is to buy another ticket . Thank God éthiopien Airline was more affordable."

Pros: "Good clean service that Swiss is known for."

Pros: "On time, even arrival 20 min earlier, very courteous and professional cabin crew comparing to the rudeness of Lufthansa one. Soft landing."
Cons: "At LHR terminal 2, same gate A, B, for 2 different flights which lead to confuse many passengers. Better signing and Public Announcement is needed. Queuing 1:30h for tax refund is totally unacceptable and leads to give up to claim your rights."

Cons: "Flight was 2 hours late. This is my second experience in a week with Swiss flights being 2-4 hours behind."

Pros: "What I liked is that they didn't really focus on the weight I had little more weight and they didn't really make an issue for me"

Pros: "Great"
Cons: "Great"

Pros: "Left ontime and service was excellent."

Pros: "Premium economy service was good."

First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me.

Cons: "need better and more food options, more often"

Pros: "I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly"
Cons: "Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!"

Pros: "Airline staff good and professional"
Cons: "Nothing one can do, for a 6.2" guy, the metal bar that forms the shape for the pouch for magazines and such digs into knees, ESP if person in front adjusts seat back. Fold out table barely accommodates laptop."

Pros: "Priority boarding was appreciated and the flights were on time. Service was fine. Schipol was good."

Cons: "Our flight was canceled from Amsterdam to Bordeaux and did not receive any direction and had to find alternate flights for ourselves with the personal expense of using our own cell phones. Then our luggage lost for 3 days. Not happy! We ended up flying from Toronto to Paris then to Bordeaux. Lost my upgrade money for seats. Now have to deal with KLM for refund!"

Cons: "The entertainment was quite dated and didn't have new movies etc"

Cons: "Service"

Pros: "Loads of leg room"
Cons: "Loved everything"

Pros: "KLM fed a sandwich even though the flight was only 2 hours. The crew was pleasant. Getting through the Amsterdam airport to catch a connecting flight with only an hour to do so was no big deal. Airport staff was pleasant and helpful."

Cons: "55 minute delay was not welcome."

Pros: "Special treat for King's Day Friendly crew"
Cons: "15 min late boarding 30 min delay leaving the gate Very little leg room"

Cons: "I missed my flight because of MU"

Pros: "Except for my negative comment, a good flight."
Cons: "I paid extra for a window seat, but due to the poor alignment of the seats with the actual windows, I actually sat next to a wall! Nol much to see out of a wall. If KLM are going to charge extra for a window seat, then they should make sure there is a window there! If the seat had actually had a window it would have been an excellent flight."

Pros: "The flight crew were kind, polite, and attentive."
Cons: "Bussing to the plane was a bit odd, but the crew remained organized in doing so. When we arrived to the plane, they had both entrances open so that those sitting near the rear of the plane would enter from the back. Plane was a little chilly, but I have come to expect that one most flights."

Pros: "Lovely crew, very good entertainment system."

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: "Flew on new A350, liked the seat TV, live map/camera. Good selection of entertainment."

Pros: "Food on this flight was delicious."
Cons: "WiFi didn't work."

Pros: "The new Airbus A350"
Cons: "Onboard food and drink is quite expensive"

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: "This was a very good and on time flight from London to Helsinki. The exit row had lots of legroom."

Cons: "Not offered a beverage ."

Pros: "Nice crew"
Cons: "old plane, not clean, flight delayed not airlines fault"

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: "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 crew were very friendly, well organized. movie selection was great. meals were surprisingly good and plentyful"
Cons: "not enough leg room. and i have to point out that I am a petite 110 lbs, 5'2" woman. as soon as the person in front of me reclined their seat to either sleep or lounge, I had my food tray on my chest and the small tv screen 8 inches away from my nose. Thankfully Im small but the man sitting next to me was rather tall and had to turn into a human pretzel to fit in that seat and space allotted."

Pros: "The flight was great...the staff are wonderful people...they are so sweet and kind...they work so hard...the service was great...I love their personalities..The Movie selection was awesome...Because of my broken leg, they were there to help me right away...amazing crew...will be flying with them again in October....looking forward to flying with British Airways again... Thank you for the care... Yours Truly, Sylvia Smith..."
Cons: "I have no complaints at all...."

Cons: "No TSA pre check"

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."

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: "I did get to move away from complaining passengers but "lost my coat" in the process. People are awful and obnoxious"
Cons: "Who doesn't turn off the plane lights at night inside the cabin? Especially when you're feeling late at night? Didn't post gate until very last minute…LHR..Then it said boarding immediately. Nowhere to get water. Hurriedly Boarded plane to find out we have the sit there an hour. Girl next to me was so childish Loud mouth complaining because she couldn't sit next to her bf."

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 were friendly, helpful and efficient Entertainment was very good, especially on outgoing flight"
Cons: "Broken a/c on one flight, sweating buckets No leg room at all on outgoing 747 Disgusting smelly BO passenger on return flight"

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 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: "Boarding was quick and efficient. Flight crew was polite, helpful and friendly. Had adequate leg room in coach, added plus was the flight was not crowded so did not have anyone sitting next to me. Did not feel squashed and claustrophobic as a result. Food was satisfactory."
Cons: "Was inadequately fed on the Houston to London leg. Got nothing but a nightcap. The following morning I received a cold, stale croissant as part of a lunch box for a preschooler, nothing warm, no protein after 8 hrs in flight. I could not check in online."

Pros: "Polite and helpful crew and great entertainment systems."

Pros: "The inflight movie selection."
Cons: "The uncomfortable chair."

Pros: "It's a direct flight, it runs on time, the staff on the ground and on the flight are professional, courteous, and helpful. If you are lucky enough to have an empty seat next to you, the seating is quite comfortable, with adequate foot and stretching room."
Cons: "For in-flight entertainment, the ceiling-mounted screens along the aisle are hard to see and offer no choices for viewing. The food, as usual, was poor. I ordered vegetarian meals, and on the return trip for both meals was given the same soggy pasta with tomato sauce--no protein (why not add a few chickpeas or white beans?)."

Pros: "The service was remarkable. Everyone was very attentive and friendly which is exactly what you would want for a long flight. The crew came around frequently to provide beverages and left you alone to sleep."
Cons: "The boarding process was a bit hectic. The flight was full which I completely understand. After everyone was settled in the plane it took another 25 minutes to leave the runway."

Pros: "Flights were on BA not Finnair"
Cons: "Ba website did not work properly."

Pros: "geting off"
Cons: "To cramped so I will go back to Delta"

Pros: "Friendly flight crew made me feel very welcome . Food and drinks service was excellent, nice choices. Movie selection was vast."

Pros: "it was fine"

Pros: "Flight operated by BA; food was excellent, wine was free, crew were friendly."
Cons: "Legroom so cramped its dangerous; worse than on my CRJ connecting flight."

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.)"

Pros: "Crew politeness"
Cons: "Food is only average and not enough good movies to watch"

Pros: "I made it home safe"
Cons: "Little legroom for such a long flight. Too crowded."

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."

Cons: "experience was awful. Helen Rowena Boysen"

Cons: "Was not able to check in online on either leg."

Pros: "The food and entertainment were good."
Cons: "This flight was operated by British Airways. The flight attendants on this flight were very rude and the plane was not as comfortable as the they Finnair plane."

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: "Great flight, crew was very nice. I would rebook with British airways."

Pros: "Great crew-service was prompt"
Cons: "Food was served an hour after we took off and we got a snack 7 hours later!! You'd think that on a 9 hour flight, there would be two full meals. Also, entertainment system was tiny (4" screen) and colors were washed out with brightness/contrast so bad, you couldn't see anything at all. Seats were cramped-I took an Emirates flight from London to Bangalore-what a world of difference!!!! Never flying BA again, that's for sure."

Pros: "Short good flight, with no issues. Friendly crew that were very professional."
Cons: "No complaints."

Pros: "Flight was not full Nice clean 777-300 Better food service than in the past ... more snack service With Global Entry, I was off the plane and in a car in less than 20 minutes"

"Poor communication from boarding staff, airport staff not a clue. Communication on board was un decipherable and airline lost baggage."

Pros: "Great and friendly crew"
Cons: "In-flight system had some problems and seats seemed a bit uncomfortable"

Pros: "The sear was messy they didn't clean it it was full of pieces of bread."
Cons: "boarding the flight on time instead of delaying it two times... and also putting the information at the flight information screen if I haven't gone to ask to the airport information stand I would never know the flight departure gate that was at the complete opposite side of the airport of were the initial flight was going to depart."

Pros: "The seats were spacious and the crew was wonderful. The crew actually made the long flight more tolerable. Will seek out Delta/Air France for further international flights."

Pros: "The crew was terrific."

Pros: "The seat was very comfortable."
Cons: "My boyfriend and I were required to gate check our carry-on luggage which required us to go through customs in Paris to get to our bag and re-enter security for our connecting international flight. I am unsure why this was the case as other passengers brought the same size luggage. Very upsetting."

Cons: "The best airline what I was flying so far !! Excellent food, drink, comfort seat, free entertainment with great selection."

Pros: "All went right namely the seats but the luggage condition is the worst"
Cons: "Air France is not a low fare airlines, I had to pay 225 USD against 3 luggages which is not acceptable. We should have the right for one luggage per ticket as all other airlines. If I knew this will happen, I wouldn’t use Air France and this will be the last time I buy a ticket on Air France"

Cons: "See above."

Pros: "Crew was wonderful and welcoming!"

Pros: "Amazing crews!"
Cons: "N/A"

Cons: "More water provided during the flight. Also, the second meal was not very good."

Cons: "Not to be late ,and not to loose my luggege"

Pros: "Good food and crew"
Cons: "Plane was old and seats were super tiny. Even an average guy would be uncomfortable in it. Can’t sit in one spot for longer than 15 min without getting sore."

Pros: "The crew was efficient and friendly. The plane took off on time and landed on time."
Cons: "Boarding was slow and tedious. People still crowd around the boarding area despite there being row for the zones. Why they don't board from back to front is beyond me. The food was mediocre at best."

Pros: "Very nice crew. Nice meal service and drink service throughout. Great choice of entertainment."

Pros: "The airplane"
Cons: "Nothing"

Pros: "The staff..the attentions..food."

Pros: "The staff were very helpful and professional."
Cons: "The food was awful and the option I wanted had run out. The entertainment was faulty and had to be reset several times. The comfort was below standard and needs to be improved."

Cons: "No space for legs. No food (just snacks). Very high temperature inside the aircraft. Flight delayed by 45 minutes."

Pros: "Not much expected as it was a budget trip."
Cons: "Poor timing in between connections, barely made in time to my first connection being the last person to board"

Pros: "SFO - CDG (Air France) was a great journey in all respects. But the one major reason for that was, the middle seat was empty. I was so fresh after the journey, would definitely recommend this flight to anyone."
Cons: "The flight was delayed by atleast 45 mins and therefore had to rush at the CDG airport to catch the next flight."

Pros: "The food was okay and the staff were friendly."
Cons: "My seat and several others around me were broken so that they would fall all the way back if we leaned back at all. The entertainment system kept crashing and forgetting what shows everyone on board we’re watching. There were no air vents to control. The games crashed constantly. The usb hubs didn’t work."

Pros: "Haven't flow with Air France for some time now and definitely noticed a lowering of standards"
Cons: "The gate changed 3 times and the terminal was very crowded. The staff seemed disinterested and distracted. The quality of the food has dropped dramatically."

Cons: "Staff where so unhelpful that I missed my flight and then refused to offer any assistance as to how I could remedy this situation. This cost me over €180 which is a weeks food and stay for me. Don't fly with these guys or with air Croatia."

Pros: "Absolutely everything perfect."
Cons: "Through my own fault I ordered a different seat instead of window seat. :)"

Pros: "Ground crew at CDG was helpful to file a claim for the lost luggage."
Cons: "Ground crew at MXP Was inexperienced. She called every one in my flight to form a new line and it was immediately total chaos. And then they lost one of our luggages!"

Cons: "Flight was delayed 3 times and when I was finally put on a flight that was leaving, they failed to check the connection in Paris (Left me 10 minutes to get from the aircraft to the other plane!) I was moved to SAA in the end after a truly traumatic time in Johannesburg. This is not the first time I have suffered at the hands of Air France sadly. Needless to say, I wont be booking with Air France again."

Pros: "Easy, fast, comfortable, no hassles"

Pros: "The crew, the service, the food and beverages"
Cons: "The 3 hours delay"

Pros: "The inflight service"
Cons: "The 3 hours delay"

Pros: "Whenever I travel air France I get a reminder of what customer service looks like on a flight. Incredible crew, great experience"

Pros: "Good boarding procedure."
Cons: "Nothing much to add for a short journey."

Pros: "Crew was welcoming"
Cons: "Space between the seats was too small."

Pros: "The hostesses were very kind and nice"

Pros: "It was on time"
Cons: "Food was AWFUL! Better to serve nothing"

Cons: "My baggage was broken"

Pros: "Crew was great."
Cons: "Food could be a bit better. White bread is unhealthy."

Pros: "leg space in plane"

Pros: "Lovely crew, clean toilets"
Cons: "It's an a380, stains everywhere, aisles between seats narrow even for business, caos at CDG, no clear queues, ground staff shout at passengers, food selection good but huge gap between describtion and reality, in JFK we waited for 30 minutes cause the docking spot was too narrow for the captain, sky priority? The economy got their bags before 1st and business."

Pros: "The flight crew and flights itself were great."
Cons: "I was told the wrong flight time, wrong terminal, wrong gate, and wrong airline. I couldn't check-in online. It was horribly inconvenient and I nearly missed the flight. We got there with 5 minutes until the doors closed."

Cons: "The flight arrived late with no clear explanation as to why. Then there was no EU queue at immigration, so more time wasted."

Pros: "Free drinks and snack!"
Cons: "Nothing"

Pros: "Wheel chair service at LAX is run by the airport. Their priority is to get you to your flight, not to a VIP room regardless of how early you check in."

Pros: "quick flight 10 min ahead schedule"

Pros: "The crew"
Cons: "Not enough room for legs. Small amounts of food. No entertainment."

Pros: "Croissants instead of pretzels was a nice change of snack"
Cons: "Computer failure rendered the check in process a total mess. Staff seemed utterly at a loss and also totally unprepared for this very early and very full flight. Most passengers seemed to have multiple bags to check. Since this is a regular flight it was hard to understand why check in staff wandered in late when time was already tight - let alone having a system failure as well to deal with. We were 50 minutes late leaving. This resulted in many of us either missing or having extremely tight (stressful) connections at CDG Paris."

Cons: "Left a little late for no apparent reason."

Pros: "The plane is roomy and bright"
Cons: "N/A"

Pros: "Good entertainment"
Cons: "For the continuation of this flight of course I was still in the same seat in the middle and I had signed up and reserved an aisle seat"
