There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

There was a loud squeaky sound the whole time we were flying.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Wretched scheduling - they got themselves into a critical crew situation and didn’t try to address it until 15 minutes before they had to cancel my flight

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Again, multiple delays and I eventually just canceled and drove!

WiFi connected but only let you go to the AA website, not even text messaging worked.

Cold air blew constantly on my legs almost making me numb.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

The flight was fine. All the delays and poor communication and customer service were the worst! We were supposed to arrive in London at 7:10 am. In stead we arrived at 1:30 pm. And now American Airlines refuses to make things right but only sent a canned apology after I contacted customer relations.
