I got more room than most, sitting in the front row.

Skipped for drink service. My eyes were closed, I wasn't sleeping, but by the time I was aware of the steward, he was gone down the aisle and serving the people behind me. Also, even though I am disabled, the steward did not help me to put my bag up in the overhead compartment, even though he insisted, the very moment I sat down that my bag needed to be placed up top. No visible plugs for headsets, or USB to charge phones. This plane looks older than I am and I'm 47 years old!

Easy boarding and finding seat; good food and liked that wine was available, good movies to choose from

Seat was not comfortable, I am 5'1" and the head rest was too high, fortunately I had my own foam neck support. Bathrooms could use more cleaning during flight as one was grossly covered with urine right after turbulence was experienced. One crew member appeared to be having a bad day and seemed unhappy to be at work and was impatient with all.

Nothing good to say about AA

AA screwed up reservations by rescheduling flights by 3 hours earlier (done not once but two times) causing 6 hour layover. This plus an additional 2:38 delay on next flight made the journey horrible. Will never book an AA/BA flight again for intrnational travel.

The plane was not busy so services took about 5 minutes, everyone had 2 seats minimum and generally quiet. Had it been busy, it would have been different in that seats were not very wide, aisles very small, if the seat in front reclines and you don't, you can't see your screen and not a lot of space in general.

If you want to select your seat, be prepared to pay £175 per flight. This is ridiculous! Second meal was a very bare bbq beef pie or sweet potato pie... On their own with nothing else and it arrived 30 minutes before we landed so very rushed. On a 9.5hr flight the 2nd meal needed to be an actual meal and come sooner than it did.

The United flight had a great entertainment package (movies, tv shows, etc). The flight attendant who sat in front of us was awesome,and fun to talk to. She gave us some great tips about things to do while in Athens. The food was good (for airline food).

The flight from Newark to Athens was interesting. The flight changed gates at the last minute. The plane was towed to the new gate, then we found out that it was going to be delayed an additional hour due to required maintenance checks. Actually, I don't mind the additional maintenance checks, I want to arrive alive! We arrived in Athens 90 minutes after our expected time. We got seats in the exit row, however, we couldn't really enjoy the extra legroom for 2 reasons: 1) The exit hatch was right in front of my girlfriend who was sitting near the window. She couldn't extend her feet without kicking the door (I big no-no at 35,000 feet). 2) Our row was right in front of the bathrooms, so I had constant traffic bumping me in left shoulder and lines of people literally standing in front of me for the majority of the flight while waiting for their turn to use the bathroom. They are stepping on my feet constantly or passing gas in my face (I wish I was kidding).

This plane has not been updated since before I was born. The seats were extremely uncomfortable and there was no in seat entertainment, just overhead screens. I was never able to get the WiFi to work. There were no power outlets, and we were never offered headphones, eye masks or ear plugs.
