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 :(

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.

I was placed in a seat assignment that I was unable to change prior to the boarding day. I showed up hours before boarding and prior to boarding I asked if I could be moved to sit next to my children. Without even looking or checking, I was immediately told that it was not possible to move anyone. I went ahead and waited until boarding at which time I sat down next to my children anyways. When the passenger that was supposed to be sitting next to my children showed up, he was very understanding, and immediately asked me if I was sitting next to family, to which I replied “yes,” after which he said “it’s okay” to let me know that I can continue sitting in his seat, while he takes my seat. However, in a very contrasting and rude manner, the very person that I asked earlier, if I could be moved, that was sitting at the gate prior to boarding the airplane, showed up across the other side of the aisle, and started screaming across the airplane, where everyone could hear, to have me move out of the seat I was currently sat in, or else she would remove me from the plane, during which time the other passenger told her (the American Airlines worker in charge) that it was okay, and he doesn’t mind that I was in his seat, making her aware that I was next to family, which is where I belonged. There was no complaint at any given time by anyone, including the passenger whose seat I was in, but my safety and my children’s safety was now in danger because of an American Airlines worker, that has no regard to her surroundings or the situation that she was actually facing. The importance and clarity that was predominant in her mind, was for me not to sit in any other seat, other than the one that I was assigned, not next to my children, even though the flight was booked for all of us at the same time. I understand it isn’t always possible to make certain seat assignments together, but when a passenger with the assigned seat next to my family is OK with me switching out with him, I would think the American Airlines worker in charge should not care, unless she considered a threat, but if I was a threat, I should have been removed from the airplane at the first sign. I was aggressive, I never raised my voice, but I did for a few seconds delay, my calculated response when I was asked to move. The passengers surrounding us were in awe of the way that the American Airlines worker in charge handled this situation, and pointed out that many other passengers in that very same airplane, just prior to our “event” had switched out their seats assigned, but I was singled out, possibly because I had requested this prior to boarding the plane. This made me wonder what kind of company American Airlines really is, and has since altered my newfound opinion of this company as a recent. I am very disappointed with American Airlines due to this event that has happened during boarding and prior to flying out on a trip I booked for my daughter that just turned 16 years of age, and her first time flying at the age of emancipation with her father.
