I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

Mechanical Delay of over an hour with multiple gate changes. Entertainment system down for rejuvenation.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

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.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Wifi did not work and they only served water, coffee, or tea.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

The wi-fi was awful. I paid $8 each way and got little , except frustration. .

not sure why you ask about food, I n3ver get food on flights except maybe cookies or pretzels. wifi was slow and in and out most of the flight not good.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

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

We loved the steward on the plane. He made the night enjoyable

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk
