Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."

Pros: "Salimos a tiempo . El business es muy confortable"
Cons: "La comida horrible . No se limpian los baños"

Pros: "Very nice airplane and pleasant crew"

Pros: "Overall a nice and good flight"
Cons: "Just a detail, my “head holder” (not too sure how it is called) would not hold in position. Also, staff was a bit slow to come after being called, I had to go and ask for water by myself at some point since no one was coming after 15minites of waiting..."

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

Cons: "The website I booked on and the Delta phone line on the printed ticket said that I had baggage when it turns out that I did not according to the check in staff and they made me pay."

Pros: "Crew was amazing, seats were comfortable with enough leg space even without choosing extra space seats. It was my childhood dream come true to fly with KLM. It was really an exciting trip for me, just that it was short."
Cons: "Well, for me everything was on point. Those who have never travelled with KLM, I would encourage them to do so and I’m sure they will not regret."

Pros: "The crew were very nice, food was tasty, seat comfortable and the entertainment great as well. Will be flying KLM again soon :)"

Cons: "The flight was cancelled and had to be rerouted on United Airlines."

Cons: "Faultless handling of weather delay, causing missed connection and flight transfer. A well oiled machine, thank you."

Pros: "Good"
Cons: "Nothing"

Cons: "Not happy to pay extra money for my case"

Pros: "The staff tried to help me when it was evident we would not arrive on time"

Pros: "Great"
Cons: "Great"

Pros: "Fabulous trip with friendly, helpful staff"
Cons: "Nothing"

Pros: "Good Experience"
Cons: "Nothing much"

Pros: "Friendly staff"
Cons: "Entertainment was dated and poor in function. Our bags were 99 dollars each and we’re both lost and didn’t arrive. I just filed a claim and got rude service saying I should have filed the claim at the airport baggage area but there was not anybody there to do the claim then he agent upstairs said they just spoke to them and they are there and I should have done it there. This was so rude and there is no way to get back into customs area. If we paid 200 for bags I expect them to arrive on time. I’m asking for a refund of the baggage fees."

Pros: "Airlines issue"
Cons: "Profiling certain customers"

Pros: "Clean airplane, friendly crew, no rush, nice snacks for a short one hour flight. Just generally a positive experience."

Cons: "Not much to comment on here."

Cons: "Two hours delay in the start."

Pros: "Very little if any."
Cons: "Aircraft was not very clean,the staff seamed quite harsh at times when speaking to customers. The food was really quite poor but it was a short flight to be honest. Overall not as pleasant as the China Southern flights. I would not like to choose them again unless i had to."

Cons: "Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess."

Pros: "Crew was friendly..business class seat was very comfortable and seemed wider than most Nice power outlets great entertainment system"
Cons: "Row 6 in business is after the first 5 rows and Galley and restroom. Very awkward"

Pros: "The flight was delayed by 40 minutes initially then a further 20 making it an hour late. Sitting at the gate there was then suddenly a last call to board the flight and a mad rush for everyone to get on. I appreciate that delays happen but the lack of communication ragardinh altered boarding times didn't make the situation any easier"
Cons: "As above"

Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."

Pros: "Flight was efficient enough and staff were friendly."
Cons: "It was delayed quite a bit and more on-time updates would have been appeciated."

Pros: "Free wee cake."
Cons: "Nothing in particular."

Pros: "Short, comfortable flight. Nothing special. Got us where we needed to be without incident."

Pros: "Quick, short"
Cons: "Left late"

Pros: "Punctual"
Cons: "Paying for soft drinks"

Pros: "took off early once they had accounted for everyone, and arrived a little early too."
Cons: "While I didn't have to check my bag on the first longer flight, I did have to check it on the connecting flight which delayed me somewhat in getting into the city of London. Not awful, but strange... Free-for-all when boarding, not nearly as organized as it was at JFK."

Cons: "Paying for inflight drinks. All US airlines provide FREE complimentary drinks and snacks. Seemed in poor taste to charge for such things made the airlines appear cheap."

Cons: "Nothing! All was great"

Cons: "They lost our strollers which put us into a really difficult situation, since we had to carry our two toddlers + our infant during the 5hour connection time in LND."

Pros: "Not a lot"
Cons: "Flew Aer Lingus twice during our trip and not impressed. Disorganized, late, confusing check in to the point we almost couldn’t check in, and very rude staff from check in to air hostess. Ryan air was better"

Pros: "That it only lasted 50 mins"
Cons: "Packed with low class beer drinking plebes."

Pros: "Short but great had a window seat so slept most of the time"
Cons: "Staff didn't engage much"

Cons: "Plane"

Pros: "everything was good as usual"
Cons: "check-in desk couldn't check me through to my connecting flight with Virgin Atlantic so I had 15mins once landed in Heathrow to get through passport security and checkin at Virgin Atlantic desk.... I'm young and fit so was able for the dash but elderly or familys would not have made the connecting flight in that time"

Cons: "Paying for beverages seemed a bit much."

Cons: "Bags got delayed by a day."

Cons: "Custom made bike box erroneously classified oversized, but they didn't charge for it so ok"

Pros: "Crew, speed, ease of security at Cork"
Cons: "The lady in 1C who turned her phone on as soon as we hit the British coast"

Pros: "Crew polite. Seats comfy."
Cons: "One person checking boarding cards at gate led to a ridiculously long queue for a nearly full flight and made it late getting us all on the plane and passengers were getting annoyed. Then whatever machinery Aer Lingus use to push the plane back from the gate actually got stuck on the plane cone leading to another delay. Knock on was we were made to wait for a take off slot and made to wait for a landing slot at Heathrow so late arriving."

Pros: "Reilly dolly"
Cons: "The other trolley dolly"

Pros: "Journey was good"
Cons: "Air lingus checked on my bag under someone else's name, now I am stuck in San Diego with no luggage and no answer as to where my bag is, very disappointed"

Pros: "I love this airline. I have a few suggestions below if you care to read them."
Cons: "You could offer small bottles of water as a courtesy. Online check in was difficult to navigate and ultimately unsuccessful. There was not a roamer person in baggage check in area to assist those with language barriers or even electronically challenged people which delays the process."

Cons: "Airline lost my luggage..."

Pros: "Punctual and on time"
Cons: "Nothing really"

Pros: "I enjoyed the turkey and cheese pretzel sandwich, but I found myself unable to get comfortable in my seat. I have tailbone issues and I was in pain the entire time being that the seat was so cramped and hard."

Cons: "Airline lost my luggage."

Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"

Pros: "Service was good"
Cons: "Seat in the middle... Delayed in the flight... Miss our connection... And baggage delayed too..."

Cons: "Our clothes and baggage wet with beer. Three days of holiday ruined trying to get clean clothes and unsucessfully to remove smell from luggage."

Pros: "Excellent all round!"

Cons: "Customer Service is Dead with British Airways!!! I will make every effort not to fly with BA again"

Cons: "Crew could have reprimanded people not wearing their masks or not covering their noses. The airline could have kept middle seats open to instill more confidence in flying."

Cons: "Nothing!!! It was a great flight!!!"

Cons: "Size of the seats"

Cons: "Better drink selection"

Cons: "For an hour and one half flight the seats were tolerable. Anything longer than that would have been torture."

Cons: "Just wish there was another few inches width on seats"

Pros: "Friendly, helpful and professional crew."

Pros: "Excellence view of London performered by the pilot. Very please with that."
Cons: "All good except for the seat, let my neck with a bit of pain."

Pros: "On time departure and arrival"

Pros: "Helpful and friendly staff"
Cons: "Filth plane"

Pros: "Crew very friendly"
Cons: "No free coffee."

Pros: "No hassle and all straight forward"

Pros: "Check in and crew were very nice"
Cons: "Baggage was slow But everything was fine Pilot kept us informed"

Pros: "I was very well looked after by crew."

Pros: "I like flights that land on purpose in a couple.troled way. This one did that. Good enough for me."
Cons: "Having to fly, but sometimes if happens."

Pros: "Short flight"
Cons: "All baggage lost. Wasn't put on the plane because they didn't have enough containers. Ground crew at London was courteous. Luggage had to be sent on to the US the next day. No free bags on this flight so all of the luggage lost had been paid for piece by piece. No free drink service; even a soda had to be paid for. No food, of course. Originating 10hr flight from Los Angeles to London was also uncomfortable, with small, packed coach seats, no air nozzles and poor headset connectors. I was very happy to get back on American Airlines for my return to Los Angeles. Wouldn't use BA again."

Pros: "On-time departure and arrival. Courteous efficient crew, both on land and in the air."
Cons: "My main gripe is that if you want a plain cup of coffee or a bottle of water, you are charged for it and can pay only with a credit card, but only if that card is chip and pin, and my US card isn't. Yes, it is high time that the US move into the current millennium and get chip and pin cards, but that is beside the point. I also flew BA from London to Seattle (part of same trip) and the on-board meal & drink service was PHENOMENAL - the best I have had on an airline in years, and I did not get charged for anything, including alcoholic beverages. How can this be the same airline?"

Pros: "Usual efficient BA"
Cons: "N/a"

Cons: "Had to take an emergency trip to London. The cost of the ticket for an hour flight was outrageous. $900 US was highway robbery."

Pros: "I got there. It was safe."
Cons: "Entertainment system shut off."

Pros: "Crew, funny safety instructions with Gordon Ramsey"
Cons: "Delays"

Pros: "everyone was very nice-thank you"

Pros: "On time"

Cons: "I have to pay for water?????"

Pros: "Comfortable and on time. We didn't have any food or entertainment so can't rate for them."

Cons: "After sitting on the tarmac (I understand the delay) for 2 hours there was no water available for another hour past takeoff. And then it was only available for purchase. Really, a cup of free water is asking too much?"

Pros: "Boarding seemed simple, no zones were called except for priority, we just all boarded and it seemed to go quickly and smoothly. BA is all pay onboard for any food or drinks."

Cons: "The cost to check in a bag was 65 pounds. We are a family of 3 and so that was 195 pounds. It is unreasonable to charge that much to check in a bag and ridiculous for ticket pricing to not be clear about this."

Pros: "Left on Time"
Cons: "Food costs money and not even water is free."

Pros: "We got to our destination safely which is always the most important thing."
Cons: "There didn't seem to be as much space as usual on international flights. The plane never got to a comfortable temperature and we were hot all the way home. One of our tv's didnt work which made for a very long 8 + hours."

Pros: "Nice plane, and quick flight to Heathrow from Glasgow. The plane had to leave late due to weather but the pilot kept passengers informed and made up time in the air so we were only 15 minutes late. The crew was available to discuss implications for connections."
Cons: "No entertainment options but this was a small plane and quick flight, so I didn't expect anything."

Pros: "Blanket and quiet to sleep"
Cons: "my screen didn't work"

Cons: "There was a massive delay and I stood in line 6 hours to rebook. Because of the long rebooking line, I missed multiple other potential alternative flights that day and had to spend an unscheduled night in the suburbs of Glasgow. Had rebooking been more efficient, I could have returned home the day scheduled. Very disappointed."

Pros: "Crew was friendly, food was good, tv entertainment has a lot more choices now, decent leg room, smooth landing and take off,"
Cons: "Flight being late 2 hours and we had to sit in the plane for that amount of time, they didn't their refreshment service early"

Cons: "Everyone was terrible"

Pros: "All was fine ......cabin crew, pilot updates, seat comfort . Keeping hydrated is a well-known health fact. Why BA does not offer free water wa a shock to me . Yes a kind steward let me supplied with tap water, but I find it appalling that the corporate office does. It consider customers health important."

Cons: "Cabin luggage is too big for regional aircraft. Size limits need to be imposed more strictly."

Cons: "Boarding process was a bit chaotic. Announcement s needed to be clearer. Also all old movies on the IFE."

Pros: "Left/arrived on time"

Pros: "Nothing!"
Cons: "Everything"

Cons: "Could not check in online"

Pros: "Staff was cheerful"

Cons: "Never landed in Coruna, we landed in Santiago, and I received one one piece of my luggage, hope I may get the rest pretty soon, very desappointed."

Pros: "My luggage was lost and had to wait 2hrs."

Pros: "We got to our destination eventually"
Cons: "Lack of communication. No explanations. Feelings of confusion and abandonment."

Pros: "The cost for three tickets were better priced using your service, rather than BA direct."
Cons: "The aircraft did not have any food on board, due to some difficulty. They were offering food vouchers at the gate once we landed. That never happened. It could have been useful as I was travelling with my two sons. Heathrow is expensive for breakfast."

Pros: "Nothing"
Cons: "I had to stay overnight because the flight came in late."

Pros: "I love the fact that British Airlines gave us many hours notice that our first flight was delayed but we should arrive on time anyway. When we arrived, the check-in agent volunteered to switch us to an earlier flight so we could make our connection without a hitch. The plane was clean, the flight smooth, and the staff was friendly."
Cons: "Too little leg room in Economy seats. Food mediocre. Long line at check-in."

Pros: "Everything is clockwise precision. All the passengers were well disciplined or rather made to be. Aircraft was very airworthy. The pilot was very experienced and nice soft landing at Mumbai in spite of inclement weather conditions"
Cons: "The food & drinks. Both offered we're mediocre stuff."

Cons: "This really is more about the flight from paris to Bucharest: I’ve literally never experienced a worse ticketing and boarding process. Old planes, ride staff (even by remarkably curt and abrupt Romanian standards). Broken inline experience. Overall unpleasant. Seems to be flown only by Romanian families with hundreds of pounds of luggage. Like a caravan."

Cons: "I missed my flight because my previous flight was delayed 2.5 hrs"

Cons: "One hour delay"

Pros: "To be going home!"
Cons: "Female crew taking orders then taking ages to ring drinks a d they move on to others instead of finishing what they were doing. Then you're lucky if you get given 1 sugar and no spoon lol."

Pros: "The flight departed on time and arrived the same. The seat was a tad bit narrow for me but then I am a tall guy at 6'5". Crew was very professional. Ticket cost was a third of what the other airlines were offering for a Sunday fare. I'll definitely use BlueAir again!"

Cons: "I was not allowed to take the push chair on board even though on the inbound flight was ok to do so. I have purchased the push chair especially so I can take it on board. Disappointed."

Pros: "The crew was well trained, kind and receptive. The pilot managed to drive through a storm and even arrive 10 minutes faster after leaving 5 minutes late."
Cons: "Passengers traveling with pets took our reserved seats. The places for our baggages were occupied. When addressing this issue, we were told to move further ahead to empty seats. There was no meal included, and the one we purchased could not be paid by POS."

Pros: "I canceled the flight 6 weeks ago, no refund issued."
Cons: "I canceled the flight 6 weeks ago, no refund issued."

Pros: "Boarding was quick and we arrived on time."
Cons: "When getting to Bucharest we were taken by bus and didn’t have a gate."

Pros: "Everything was quite fast, we were like 15 min before the plan ready with boarding, but then somebody needed medical assistabce and we left 15 min delayed. But that's ok, it's nobody's fault. Baggage arrived very fast in Hamburg."
Cons: "A minus for the Crew because when we arrived in Hamburg, people started to open the baggage boxes although we were still rolling (like 5 min too early) and they didn't say anything, so more people were following. When we arrived, almost all the people who could, had the baggage already with them. This happened in the past but the Crew stopped the people on time."

Pros: "What to like? The rudness? The delays? Or the fights on board!!!"
Cons: "The flight was delayed with nearly 2 hrs. Cabin crew were rude made as feel very uncomfortable. This flight as whoke was the worst one I have even been too. Never ever again. BLUE AIR NEEDS TO SORT ALOT OF THINGS BEFORE OFFER SUCH SERVICES"

Pros: "Stupid survey can’t eliminate category that doesn’t ajgpply"

Cons: "I was unable to check n online (although the process was intitated well earlier than 12 hours prior to departure). The system charged y credit card for a seat reservation and then crashed with an error, both on my phone and laptop browser. When I called at 9:00 am (when their offices are open) to ask for help with what happened, I received no answer other than, "the check in system has just closed. I am unable to help you in any way". I booked another flight with another carrier, and did not take this flight., not do I plan to book with them in the future That being said, it is not the job of the employee to defend a poorly working system. Services need upgrade asap."

Cons: "flight delayed by more than 1 hour"

Pros: "The added touches make all the difference! We didn’t expect free food and was delighted to receive breakfast. The chairs were much more comfortable than any other plane I’ve been on due to the adjustable head rest, and as a regular flyer to Cyprus, this made a difference. The sweets served just before landing is an excellent idea and something that we do need due to our ears, so this was appreciated. staff were attentive and pleasant."
Cons: "To have the menu and duty free booklet at the beginning of the flight would have been helpful."

Pros: "Flight Attendants very good"
Cons: "Dusseldorf to Warsaw: Boarding terrible including assistance and messaging. - Boarding chaos - Late flight out of Dusseldorf (about an hour) - Just before landing, pilot announced all connections would be made - (and even mentioned chicago) - Connecting flight was gone when I arrived at gate, and I was quick in getting to gate from prior flight - next flight caused 5 hour layover in Warsaw Warsaw to Chicago Boarding terrible including assistance and messaging. - Boarding chaos - Late flight our ot Warsaw (about an hour) - no messaging at gate about reason for delay - kept increasing departure by 5 minute increments; started at 16:40 ended 17:05 (I beleive) - once boarding was complete, pilot said delay was due to wait for connections (boarding was an hour and 15 minutes late). Very frustrated"

Pros: "They are more professional and helpful. Really seemed like they knew what they were doing. The flight crew was accommodating and polite. The plane was very comfortable"

Cons: "7hour delayin onnecting flight! Seats on plane torn and very uncomfortable, meal booked but no food available."

Cons: "Flight was rescheduled for 3 hours later than original departure. Check in opened less than two hours before the rescheduled flight time so everyone was stuck waiting at check-in for hours. We couldnt even go in and relax inside at restaurants or the gate because online check in wasnt available. Then the flight was further delayed with no news about when the new take off would be or why the delay. Finally boarded a tiny plane that had propellers and a loud take off, if you easily fright on planes probably not the best choice for you. And then someone started smoking on the flight and the attendants had to announce again that smoking wasnt allowed. On and off throughout the flight it smelled like someone was smoking so I wonder if it was even coming from the cockpit."

Pros: "The free snack (biscuits and drink). The hard-working attendant (having to stuff all the baggage into the overhead lockers). Boarding at the rear door enabling me to get to my seat early."
Cons: "A slight whistling noise coming from the rear of the cabin, not too bothersome but it's there (I think the plane is getting a bit old). Not being able to disembark from the rear."

Cons: "It was very hot on the plane. There was no legroom in my seat, it was very uncomfortable."

Cons: "It was very hot on the plane. There was no legroom in my seat, it was very uncomfortable."

Pros: "Crew, polite and friendly"
Cons: "delay of more than 6 hours and incorrect information"

Pros: "company gave out free drinks and snacks"

Cons: "They change the fly departing time with 12 hours before I was flying"

Pros: "Easy to book on phone no problems getting boarding passes etc."
Cons: "Could not amend my booking tried to check a bag online after printing out boarding pass. Had to pay £46 for a 11k bag each way."

Pros: "Very good airport check-in and flight. The Check-in staff were quick and efficient and the Flight Crew were friendly and attentive. It was calm and restful."
Cons: "The internet support. I spent meny hours trying to check-in and upgrade my case allowance from 20kg to 32kg, and failed. When I tried to change the baggage weight to 32kg a charge was added for NOT taking the case PLUS the extra for the 32kg case! The cost of a case is reasonable and I would advise to pay the extra £5 for 32kg for most flights. The on-line Seating Selection is also unreliable, I was seated next to an empty seat which had been showing to be unavailable on-line! A response to my query which I sent to Blue Air arrived when I was in the air on the flight! It only repeated the baggage section of the Confitions document! Thank goodness for the excellent airport check-in staff and the Flight Crew!"

Pros: "On time ,clean aircraft..."
Cons: "Crew was very serious...a smile can make a difference....."

Pros: "The flight went well."
Cons: "Bag drop off was terrible and stressful. We arrived 2.5 Hours early to drop the ONE suitcase and have brunch. We queued for 1.5 Hours to then be blocked as all six counters were given over to another flight and people who arrived LATER then us for our flight got to go first. It was incredibly stressful and frustrating especially when I checked in online before arriving at the airport. We had to rush and run through the airport and board at final call. In fact it would put me off flying with Blue Air again."
