The food in first class has taken a big downturn

Nothing available at the assigned hotel as far as brush, toothbrush, etc after forced layover with bags that departed

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

The seat when "flat" was not flat and pad was too thin to cover it.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

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.

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.

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.

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

Incredible. The upgrade to Business was a phenomenal way to end my trip, beyond grateful for the generosity and hospitality.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

Service of the crews were great. Food on flight was very greasy, and salty.

Terrible, broken window and the blinded didn’t shut during the entire flight. Nobody could sleep

Horrible. Crew is not helpful. Lounge is sub standard and overcrowded. Getting to your plane is underwhelming “via a bus”. Worst experience I have had.
