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

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

Everything was great except for the seat. The backrest would not stay in the upright position.

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!!!!

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.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

American Airlines continues to price it can provide the least comfortable passenger experience in the air. This legacy carrier rivals the budgets for both terrible seats and inadequate amenities. I am a 5’7” woman who is not wider than a coach seat (even on these narrow bodied aircraft). My 3.5 hour flight was terribly uncomfortable because the leg room is inadequate (my knees hit the seat on front of me even when it was not reclined); the seat barely reclines; and the foam padding is worn thin to the extent one can feel the metal supports of the seat. Add to this the fact that the aisle is super narrow, so that the drink cart literally scrapes the arm rest of the aisle seat. It’s basically torture.

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

after boarding on phx to sjd, crew discovered that one of the megaphones was either out of date or not working. It took 90 minutes to get a replacement and do the "paperwork." That is really unacceptable. Why wasn't the megaphone problem discovered before boarding? Is it part of normal maintenance check? who is responsible for checking. How can paperwork take that long? Fortunately, SJD was final destination for most travelers so very few if any passengers had to miss connections.

Flight From PHX to CVG was on time, very professional staff

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Flight attendants used to be nice to people. And any flight over 5 hours should have some kind of food other than tiny pretzels and one drink comped.

just overall disappointing, not a treat to travel these days....paying for Main Cabin Extra was not worth it.

The usual wait at Columbus once you land to get to an open gate (20 minutes) and then the usual 30 minutes for your luggage to appear.

American airlines put us on a connecting flight that only had 20 min layover. I made it by running down the concorce in Phoenix and was last one on the flight. Not acceptable!!!!!!!!!!!!!!!!!!!!!!!!!!!
