Made the Atlanta to Pittsburgh trip many times, with Delta no issues

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

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.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.

Help was available but timing was bad in my case

It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.
