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.

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Ground staff a baggage drop in Palma were generally unhelpful. The flight was delayed and the boards were never updated and there was no communication on the length of the delay.

Over 2 hours delay, communicated last minute - and no acknowledgement by flight crew

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

Notified as to why there’s a delay with our flight.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

We had a fantastic crew, super friendly and very helpful but the actual boarding part of it was terrible. You actually felt like we were going to a Third World country to be honest all the way up to the airport and the way it was split up going in all different kinds of directions and no one knew what they were supposed to do was extremely stressful

Very good except my gluten free coeliac meal was not loaded

Crew is always very pleasant. I solely fly one world and always have great experience with BA. Thank you!

I'm flying several times per month in business class. You had the worst food by far from any company I have ever flew with. The Spanish wine was great. I purchased Internet, but it didn't work well for most of the flight.

I liked the crew and boarding, short wait between flight was great. My problem was that the WiFi was not accessible through my phone and on the trip from Britain and Larnaca I didn’t have much entertainment. On my way there I felt that the didn’t give up much food for a 6 hour flight….I didn’t eat much in between flights assuming that they will serve something more substantial than what was served so I was really hungry when I was in Cyprus

Boarding from the SFO lounge is a big improvement. Although the first class dining room inside the lounge is becoming very crowded.

Decent flight, helpful middle seat blocking in business. Boarding staff was polite and helpful. Unfortunately the airport directions to this gate were a mess and the check in staff did not alert us to the confusing signage or any proactive information about the lounge. On board the flight, food and drinks were decent but average. Comparatively, SASs new business catering on this route shines above both in quality and service

we originally had premium economy seats when we booked, but because we were forced to re-book because the first leg of our journey was delayed for several hours, we had to fly economy. Less room, less comfortable.

Flight was fine. We were in business class, so lie-flat seats were appreciated. Kids were in premium and said it was nice. Flight was delayed by 3 hours, so we missed everything we had planned in London the first day.

The calls for our boarding group weren't heard/clear.
