Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.

Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.

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

one meal and one breakfast or sandwich instead of two meals.

Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.

You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.

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!
