The homeless eat better than what was served on that plane. Pretzels and ice cream? My last trip to Europe. Everything is small, but the bill.

The homeless eat better than what was served on that plane. Pretzels and ice cream? My last trip to Europe. Everything is small, but the bill.

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

So overall the flight was just average and nothing special. They overbooked some of the flights and they ended up running out of overhead storage space so we had to check our carry-ons which wasn't terrible but we were inconvenienced because of the second connecting flight with a long layover we couldn't get our bags until the final destination. Most of the flight attendants were pretty good and overall the meals were not that great because the chicken was dry and overcooked. They also didn't provide butter or any kind of spread with the bread which is cheap and concerning. The American airlines staff at the check-in counter was kind of unprofessional because this lady just started singing in the middle of checking us in and that's weird. The worst part of the flights was the terrible conditions of the bathrooms which were unclean and did not have toilet paper or toilet tissue available which is kind of insane for a 14-hour and 8 and 1/2 hour flight.

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

Awful customer service, horrible experience. We travel a lot domestic & international- worst flights to/from ever. Brief bkgd as Inhate to relive this experience: booked and chose 2 seats 4 months prior in Premium Economy - last row end seats close to bathroom, no one behind us, plenty of legroom;, underwear storage — flown this was on other airlines, love it. We receive notice 4 days before scheduled overseas flight - plane has changed, new seats assigned. Seats are split into single seats, opposites of the plane, FRONT Row so no reachable storage. Called BOTH British Air & America. American “switched planes and the seats you want are taken;” British Air “Yes, we’ll be glad to accommodate you (type type type). Just ask at the Gate and someone will give you new boarding passes with seats together in middle, OK?” — OK. —At Gate the attendant looks us up saying “No, it is an overbooked flight and yours are the only seats available.” But but but wait, “We were TOLD our seats had been switched and seated together?” Gate attendant “Well they were wrong and don’t change your seats. Your original seats are where you’ll sit.”. Right. No help WHATSOEVER. We sit opposite on way there, wife VERY disgruntled, a Tol 5 worst ways to start a 3-week bus tour of UK. We promise to NEVER FLY AMERICAN OR BROTISH AIR EVER, and we have 3 more extensive trips planned..

Requested early boarding to disinfect seat, tray table, etc. before general boarding. Instructed to board after wheelchair passengers. Waited on jet bridge behind 12 wheelchair passengers. Stopped immediately after entering plane to wait for gate agent in rear of plane cleaning a seat that was wet, got to my row and found both seats adjacent to mine already occupied, with the lack of room making it impossible for me to clean my own space and defeating the purpose of my boarding early. Cleaned the armrests and tray table as best I could.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

I was downgraded from first class to coach due to an airplane change. They pulled me out of line and I was the very last person to board the plane stuck in the middle seat with no overhead place to put my carry-.on. Very poor customer service.
