Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

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.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.
