Great. I had to modify a flight. That was easy and free. Thank You

I noticed that the planes seem to be outdated.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

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

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

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

Waaay too small plane. They also need to up the size of the overhead bins. I would love to keep me 3k with of camera equipment in my hard case baggahe instead of it being thrown into the belly of the plane

Attendants were pleasant and the flight was smooth and relaxed.

A little late at the start but all worked out well.
