The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(
You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.
This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.
Always getting updates by email very easy to check in on line. There was plenty of checking in staff to get you all through. It was nice that the flight attendants took time to talk to you and were interested in your holiday.
Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault
Food was very average. And top up drinks offer was absent. For a 11 hour long flight that should be the minimum. The crew didn't want to be there. I understand it was new year day but given they had signed up for it
It was my fault choosing the seat nearest the entrance but it was ok.
It was good, the staff was friendly and it was a typical flight to Europe.
My flight was a little marred by poorly fuctioning / loose headphone sockets meaning I had to move twice. The meals were good and the staff are always amazing, attentive and friendly. My bag was lost on my previos trip with BA for 15 days of my 18 day trip, however I experienced no such issues this time despite my fears. Overall ok but aircraft need better looking after.
