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!

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

Inexperienced boarding crew allowed too many bags on to a full flight and delayed takeoff causing a missed connection and unplanned overnight stay. There was a hotel at the airport but Delta would not pay for it offering only to shuttle me to an area hotel. Never even offerred so much as an apology by anyone working for Delta.

Staff was great! Kind and cordial! Middle seat row 28 seat B has a hump in it. Trays were getting stuck when putting down and up. Good flight

Departure was delayed resulting in me missing my connection. Delta did not autimatically find me another flight.

The seats weren’t reclining even though it wasn’t as exit seat

It was good because we traveled without luggage, carry on only.

The seat cushions were very worn so they were extremely uncomfortable.

Delayed, no updates, had a rewards number but was not working

The seats from lax to DFW was so tight that I could not move my legs . No WiFi and had to pay . Not a good selection of entertainment

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

The professionals have excellent customer service, the seats don´t have enough space.

We were upgraded to First Class and it was a great flight

Amazing I love American. I’ll never fly anyone else if I can help it.

I love American. I’ll never fly anyone else if I can help it.

Flight delay and multiple gate changes including a change near boarding time to another terminal, which in DFW is a pain. Pre-boarding delay and also a further delay on the ground after boarding. About an hour and a half total delay.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

I know Spirit gets a lot of criticism, but I've taken three flights recently and all were very good, and tremendous value. On my most recent one, they randomly assigned me to a very comfortable exit row seat! The flight was on time and the boarding process was smooth, and the crew was friendly. No complaints!

My experience with spirit was horrible I had to spend a extra $100 to check in my bag when I already purchased my ticket even when I got to my gate to get my seat the attendant didnt say anything until I was boarding the plane..also to make matters worst I been flying from Florida to New york and Florida to Atlanta often this was my 4th trip to Atlanta with the same bag and never had this problem till yesterday so im extremely upset and I wasnt even giving a reason for the change the attendant just gave a attitude and wouldn't answer me at all

Paid for wifi the day before but wifi was unavailable on flight.

Flight was not on time and it was very annoying flight. Keep changing gates.

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

The flights were very uncomfortable the seats don't have much leg room at all and they are pretty hard as well.

It was delayed but the landing was the smoothest in a while that I’ve had.

Second time in 3 days I walked off the plane late. This time - almost an hour.

Everything went well. The flight was slightly delayed however we landed on time.

I've flown two Spirit flights recently - boarding for one was somewhat chaotic, with the board listing the wrong flight and causing much confusion; boarding for the other was very smooth and easy. My seat (for which I did not pay extra) was a bit narrow and without great legroom, but it was fine for a NY-Florida trip and was more than worth the low price I paid. The crew was friendly and one flight landed early and the other was only very slightly delayed. All in all a very good experience.
