Wonderful service and comfort. Attentive and careful. The food was also better than US carriers. Highly recommend

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.

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.

Premium economy was not what was shown, no leg riser, seats were broken and do not recline more than economy, food, we couldn't eat it was so bad, no menu 1 item and it sucked.

Our original flight was cancelled. This was a slightly earlier flight. We were business class and it was very good. The staff were marvellous and very helpful. Pity our baggage didn't make it!

British Airways is very good... Taxiing after landing took 35 minutes, can't really blame the airline but the terrible infrastructure at JFK.

Our section of the aircraft in premium economy was very cold. We asked the attendants twice to raise the heat but it never happened. Even with the blanket it was chilly for 10 1/2 hours

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival
