Seats were really tight and the seat belts did not give enough slack.

Seats were really tight and the seat belts did not give enough slack.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

The WiFi has been awful on my last few Delta Air Lines flights.

Only one side of the heafphone jack work. Crew was friendly and helpful.

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Don't need the male flight attended lecturing. The whole plane on how to act when there was no problems.Other than that everything was great

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

The plane was very warm and the crew turned on the lights for the entire snack service.

Due to an issue with the plane. We waited almost 2 hours to take off. The service reps were great. We had a longer layover but was able to run for it and catch our flight. This also happened on our way out. Maybe the planes need a good look over. The people who work front desk and flight attendants are the best

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.
