Airline reviews

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.

We departed late, and we arrived to Atlanta late for our connecting flight to Quito. I asked the flight attendant before landing to please make an announcement and let us go out of the plane first she agreed but never did the announcement. We run and arrived 3 minutes late and they closed the gate of the plane. We ended up staying one day in Atlanta for the next flight to Quito. When we arrived to Quito 2 of our 50lbs bags arrived completely broken and destroyed. I made the complaint and so far nobody in Delta wants to help.

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

l really enjoy very much the flight was very pleasant

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

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.

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.

Little warm on the plane and delayed for an hour
