The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Flight was on time, staff are friendly and helpful onboard.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!
