Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

Terrible boarding , Business class seats are sub standard. As usual crew will miss your food too

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

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
