Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

2+hrs delay without any reason provided and a cramped flight

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

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

Not one thing to like. Three flights all with “mechanical” delays. Never got to where I was going and spent additional $500 for a hotel room. American Airlines is the worst in the industry!

the first flight smelled like urine Ac didn’t work pathetic experience

It was canceled at the last minute. While I was literally at the airport. Messed my entire trip up.

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

temp inside the plane was very hot and could not be adjusted.

Terrible. I did not like the delay without recourses to help passengers to get to their destinations. AA used to offer coupons for food and overnight accommodation, but not this time. The flight planning was terrible despite of all the current technology available; AA could have informed passengers better that the replacement flight is impossible today, instead of stringing passengers along for 6 hours before cancellation, so that passengers can make earlier alternative arrangements to get home.

It was a bus not a flight. Okay bus ride.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

Pulled out of the gate only to sit in the tarmac for an hour and a half for paperwork. Paperwork. Went back to the gate to refuel.
