Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

Boarding was quick and i made my connection early due to early arrival time

My flight was canceled, and instead of rebooking me on a non-stop first-class flight for the same day, which I originally had, Delta rebooked me on a one-stop flight for the following day. When I checked the Delta app, I noticed that there were available flights for both the same day and the next day. I believe this indicates poor management on their part.

Aside from a completely packed plane, I really have no complaints.

The flight was very good and the staff was very friendly and helpful!

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The food is terrible. The staff is wonderful. Comfort is good.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

Flight was on time, the staff was personable & professional, & the plane arrived on time.

My flight was delayed several hours, which is to be expected (American never fails to disappoint me!), but the parts that really bothered me are as follows: 1) I was unable to add myself to the standby list for another flight in the app, nor could the gate agents figure out how to help me do so (the app is difficult to work with and simply did not allow me to perform the action of adding myself to the list) 2) When I asked the gate agents to add me to the standby list, the agent said that he had added me, but I was not able to confirm that I was on the list in the app; as it turns out, I had NOT been added to the list after all. He had lied to me and/or failed to add me to the list. 3) I figured out I had not been added to the standby list when I spoke to the (rather rude, snippy, and dismissive) other gate agent, who finally did add me to the list after giving me some pretty unnecessary attitude. I understand that gate agents experience the worst of stressed travelers every day, so I appreciate that I was eventually able to make it onto the standby flight with their help. However, the app needs some SERIOUS attention!

Nice ! I am gold member at United Airlnes probably I will shift at American Airlines and JAL ! Thank you ! Kindly maintain quality service I fly often! ❤️

The flight was delayed 4 hours, and when we finally boarded, they told us that the fuel was only just then checked. So, we waited even longer to take off.

Everything was done like clockwork and I find no fault with the airline.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Gate change was a little tough but it was a good flight otherwise

Great flight, great service but most of all- our luggage made the trip with us.,
