This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

I just can’t understand why are you sell to many tickets ???? We had to wait 2 hours before 13 people from our flight take money and go to next day flight!

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

It's fine but Newark to Nashville was too long

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

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

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

Very good I can’t complain one bit. Thank you American Airlines for making my flight enjoyable and safe!

Flight was fine, but not having WiFi was a major negative

Everything was excellent and I enjoyed myself. Thank for everything

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.
