The cabin temperature was nice and cool. The wifi was not working.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

As previously noted, this flight was great: departure was timely, the crew was friendly and attentive, and wifi connectivity was seamless. In particular, I appreciated that the flight attendant just told me to stow the laptop right before takeoff/landing, and trusted me to do so (which I did!).

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Entertainment is ok! Boarding and seat with zone is terrible. I paid for the seats but you didn’t give me what I paid for which is exit isles.

the crew cancel the morning service due to the weather. Then the flight got deverted to Nashville . we were on the ground for over two hours the only gave us water once... no food or any snacks.... the crew should have handled better and offered something to passengers.

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

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

Offered to check carry on to final destination. This is the most absurd thing in the world. I'm carrying on because I need what is in the carry-on. I'm okay with picking up at next stop but then I will be on much larger plane that can accommodate it. Also, if there is ever a change to your flight. Go to the airport and have the people there fix your ticket. Don't do it over the phone or online with United they screwed us up and ended up with flights for our last leg that took off before our first leg.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Crew was great. 2 1/2 hour delay was due to staff needing "rest" was avoidable and self inflicted as United not willing to hire enough crew to keep flight on time.. Ridiculous. The crew and the passengers both suffered due to this.

Fine not above and beyond as I had a connection that was delayed due to maintenance

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

It was great. Smooth flight, comfortable, left on time and landed on time.

Horrible experience upon landing. Probably more due to DCA utter incompetence than AA.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

Flight has been delayed every time I've ever taken it. Seats uncomfortable. Children behind me yelling the entire flight. Some of this is out of their control but overall just consistently not a great experience.

Poor communication ahead of time about flight delays and old planes/other equipment.

Never going to fly your airline again if it can be avoided.

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

Other than nearly three hour delay for maintenance issues, everything went smooth

Snow delayed boarding several times, which I understand happens. Issue I had was that after we did board, pilot told us we were going to roll out to be de-iced, then on our way. We were de-iced once, taxied to the tarmac and then stopped. Sat for another 30 minutes or so, the another de-icing. Then we rolled out to a parking spot, only to sit for another hour due to a traffic stop in DCA, which I'm confident they knew would happen before we boarded. Pilot gave no updates other than we had to hold, attendants did speak to the crew, but when asked, said the pilot would be updating us. We on the ground in the plane waiting for over 2 hours. They did communicate that bathrooms would be open, but no other news until we left. Would have been better to be up front about status.

Flight was delayed. Not much information on when the flight would take off. Eventually we were told it was maintenance. App was not giving updates.
