The plane was a long way from departure lounge. The plane looked tired but got us there.

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.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

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!
