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.

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.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

Work being done at DIA made it difficult to find BA desk.

Food and crew were consistent with a high-end airline. App is on the level of what you’d see for a small regional carrier. I was charged $600 in fees that the gate agent in London assured me I wouldn’t have to pay, additionally, the app charged an upgraded seat choice and then put me in a less expensive seat. No response to emails to BA asking for help with refund. Probably won’t use BA again if I don’t get a response. In the air, BA is a world class airline. On the ground, they seem to operate on the level of a discount airline like Spirit.

The airplane was refreshingly silent in flight than Airbuses, landing was very soft and secure. Food was also warm and light , not a big fan of curry though. Staff was polite, discrete, professional and helpful.

I was booked in Premium Economy and never given a chance to choose to purchase my own seat. Ended up with a middle seat, which was very difficult for me. The airline then left my bag in London so when I arrived in Instanbul it was not there. They delivered it to me the next day but many valuable items had been stolen. I've been flying with BA for years and this was the first time I had such a bizarre and bad experience with them.

It was good. I really liked the breakfast which was served.

My bag stayed in London - it didn't arrive in JFK and I was informed it would arrive at my address next day. I'm still waiting for my bag and it has not been delivered. I have an air tag, my bag arrived at JFK airport around 12pm and it has been moving between terminals since then. Now they said it may arrive 1 am or tomorrow. I'm jet lagged from my flight from India, without my suitcase and may need to miss a work day (Monday) because my suitcase was not delivered at the time it was promised (today, in the afternoon). The suitcase delivery service is not reliable and I'm not happy waiting around the entire Sunday to hear that it may or may not arrive today.

The worst experience with British airways that left me with a delayed flight until the next day and no hotel accommodations available or food voucher. I still have had anyone follow up on this matter

Always the same, boarding starts before the plane is ready so we were all standing in the sun and 36 degree heat on the tarmac. Once in London, packed like sardines in busses to the terminal. BA have a way of making you feel like they dont want you as a customer.

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