It was one hour 15 minutes late taking off so we missed our connecting flight in Philadelphia.

Crew did a great job, but aircraft was old and bitterly cold. Arrived early in CLT but had to wait for 30 mins for a gate. I knew in the plane what time we were arriving 8 hours before landing and it's basically an American Airlines airport, think they would have had space for an international flight lined up lol

This aircraft was much better than the one we took two weeks ago to Edinburgh. The legroom was fantastic (two rows in front of our seats on the last trip), the seats were more comfortable, and the overall experience was improved. The movie selections are awful, unless one likes violence, intense contention, and sexual content. The so-called family films are limited to animations in spite of the many quality live-action films actually geared towards families. A note to Kayak and the survey engineers engaged to gather meaningful data for future passengers and possibly their clients: in many instances, the data you gather is skewed because you provide no "N/A" options, which forces one to choose an option that is not representative of the experience. I recommend your surveys and questionnaires undergo a serious review and update so that the data you collect is meaningful and represent accurate conditions and responses.

Cabin crew were good Food could be a lot better

Really good, premium economy is worth for a daytime flight coming back from europe

Horrible! We departed out of terminal 5, not only was the sign for flights and gate information were so badly organized that it took 2 minutes for all of the flight info load for the correct airline. One would think BA would have new and well managed jet ways, but no you had to take a bus to the plane. It took for every and detailed departure by 40 mins. I’ve had better class of service from Indian Airlines. BA needs to work on upscaling to meet the Industry norms. I can see regional airlines using this loading method but not on an international flight.

Plane features were VERY old and outdated. footrest cushion was completely lose, plane felt dirty and a bit grimy. i was in business class. the lead flight attendant, Mary made a few announcements that didn't seem to put the cabin at ease (it didn't necessarily bother me, but could have bothered others). she said "the seat cushions aren't FDA approved, so you have to put them on after we take flight." everyone had already applied the seat cushions, and saying something isn't approved for flight may cause alarm. she also said at one point over the announcement ... "we can't get up because we are too afraid of the jet stream impacts" -- again, not helpful to those who are nervous fliers.

Extremely comfortable airplane, everything looked brand new, how lovely! My seat in Premium Economy was ever so comfortable, I did not suffer the usual backache I suffer when doing the transatlantic flight. It felt like seating in a reclining armchair. I loved the foot rest, did not need to use the portable device I usually carry along with me to replace one. I loved the spaciousness in front of me, and that there were only two seats (Instead of 3 in coach) in the window row, wow what a difference in comfort. Coach seats are always just a little narrow for my hips. The support of the cushions was great, firm and offered good support . It was easy to come out of my aisle seat, although I'm 70. The staff was courteous, both meals were delicious, very carefully prepared, and creative (fruit + cheese for the second meal, instead of the usual bread sandwich)

The plane was up-to-date, and the free wi-fi was very much appreciated! All of the ports functioned well, and the entertainment choices made the flight much more enjoyable. One of the flight attendants was unfriendly, but the flight was enjoyable overall.

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

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

We never made this flight due to the flight from Barcelona being delayed, which I have reviewed in a separate review. But I can tell you that the Delta Airlines flight that did get us home, I am extremely happy with them and their crew. The only one person that I would praise within the entire part of BA is the girl I spoke to in the call center in India. Who completely understood, was dedicated to a resolution and was a complete realist in the situation. Unlike some of the people who don’t care about the human element and stick you on a flight whenever. She got us home.

better seats (very uncomfortable), access to wifi was a nightmare, and food was blah.

Gates were changed at Heathrow with nothing show on the board about 200 plus people needed to take a tram to another section of the terminal. At JFK airport, we had to wait 1 hour(!) on the tarmac after a 7 hour flight to get a gate to deboard!!

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They are disorganized….show your flight info half an hour before take off, so you are running all over the place. Customer personnel are not helpful, and act like you are bothering them when you asked for assistance - very rude!!! My very first and last time flying with British airways… good thing we have other options.

There was no entertainment offered or expected, so please disregard my readings of that component. The flight was fantastic. Efficient boarding, takeoff, and even early arrival!

2 hour delay with very little information given. Horrible service by BA employees at Heathrow after we missed our connecting flight. Extremely disappointing experience!
