Boarding was slick and the plane left on time. Staff were all lovely.

Friendly crew, cabin clean & tidy and flight on time. Great experience

Good flight, friendly staff. Only a short one so no refreshments expected but they offered a glass of water which was welcome.

Seats too small. Really uncomfortable if neighbour is fat or simply selfish and invades your space.

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

My only issue with my flight to Jersey was that the Gate wasn't announced until shortly before boarding, otherwise all went well even with how busy Heathrow was. I appreciate British Airways staff's politeness, hospitality and positive energy.

Boarding was smooth and speedy. Pilot explained route and that even though we taxied a little later than planned a tail wind meant we landed earlier than expected.

Cabin crew was very good. No wifi and no doors to the suites

Very timly. Great service !!! Pick up after meals can be swifter.

Straightforward boarding process. Pilot kept us informed during the flight, especially highlighting the fact that we would experience "significant braking" when we landed on the short runway in Florence. The flight attendants were pleasant. My chief complaint is that I was stuffed into a seat in the rear of the aircraft (row 29?). The seat pitch was soooo tight that my knees were hard against the seat in front of me as soon as I sat down. One inch more room would have made a difference. Thankfully it was not a super long flight, but it was quite uncomfortable and I had to work out the kinks in my knees once I deplaned. Is it really necessary to have the rows this close together??

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place
