I like all the Support that I have received during my flight.

Flight cancelled at last time 3h before and it was unforgettable because we have working engagement and we need to go home. Im very disappointed for this flight

They flew us to Zurich and have us layover there for a night with very last minutes notice, so we had to wait at the airport for 6hrs.

Plane and luggage on time Too expensive No comfort Poor sandwich

They didn’t have enough meals for a few last row passengers.

No SMS receiver for the check-in, obliged to do again the check-in for the corresponding flight

even with delay upon departure, the crew managed to get us on time to Lux, nice relaxing and generous service.. Classic good quality products. The opening time for the drop off was a bit late.. long queue of passengers waiting already before desk opened.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

My flight was delayed 1 hour. My Mood was not great

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

Keep track of your departure times and communicate in Airport. I could have spend an hour more in my lounge

That airplane is the most uncomfortable I’ve ever flown! Flight 267 LON-PDX Aug 10, 26 The middle armrests didn’t go up all the way. The aisle arm rest didn’t raise at all. The leg room area was compromised by a large metal box on both exterior seats. The headrests didn’t flatten. We got an email apologizing for no WiFi, but on the plane we’re told there would be WiFi. I never got it to connect. Pre-boarding support was great. Boarding was smooth. Crew was great. Food was DELICIOUS. A different plane would have resulted in a much better score.

Lovely attentive staff and even though take off was a tiny bit late, the pilot landed us early in PHX. Smooth easy journey and good touchdown.

My first check in at my origin checked my visa for my international flight but it needed to be checked again. While this is understandable, I had to wait in line for 2 hours to get this second check. More agents are needed to process travel issues in Heathrow. There were times during the 2 hour wait that there was only one person servicing the long line (I don't know where the others went). There were many agents milling about but not working the desk so it seemed as if there were plenty of people at work that day. I attempted to use the automated kiosk but because I had a new visa (not one in my passport). Again, most of this was understandable travel delays but the queue processing time was just horrible.

Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good

My screen didn't work for the first 9.5 hours of the flight. The crew could not resolve. I don't watch much media so I had been really excited to relax and watch a BBC special but couldn't. Then I tried to use the online streaming on my devices - that never worked but I do have about 7 charges on my credit card that I now have to dispute with BA. Pretty annoying. Also, they ran out of meals and they served meals that had a serve by date of 1/26. But the staff were all very friendly and helpful when they could help.

Very bad check in service. They hardly spoke of any English - at least in a way to communicate. Downgraded from Business due to seat malfunction. Could not even allocate a seat in economy with an empty seat next to me. So called manager at check in was a total waste of time

My flight from Zurich to London was delayed 2hours and 45minutes. It was awful.

Not enough food for a 4 hour trip…Lack of entertainment and with no WIfi accessibility I didn’t figure it out how to access free WiFi

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

We spent twice as long on the runway waiting to take off as we did in the air.
