The crew was very inconsiderate and rude. My flight was scheduled to depart at 6:00am. I received a call from the crew at 5:40am, asking if I was going to make the flight because I was the only one that hasn't boarded yet and boarding ends at 5:50am. I let them know that I will be at the gate in a few minutes, before the 5:50am cutoff. When I arrived at the gate at 5:45am the gate was closed. Departing early on last minute notice without having all passengers on board is inconsiderate and unprofessional.

Very easy to use and convenient, you can perform any action within the same portal

Okay considering we had weather delays which the Pilot notified us of immediately!

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Stop changing gates. Stop cancelling flights Stop moving my seat.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

It was very cold because the air conditioner was on high power, and my son got sick.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

I was very unhappy with the lack of communication from the cockpit. It took close to a half an hour before we took off after the doors were closed, and we got no announcements as to progress. It would be nice to get some acknowledgement of the situation and updates as to when we are taking off.

The seat was not even cleaned. It has full of cookie crums probably from last flight's passenger. Its basic expectation that, seats are clean.

Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

Significant delays on my trip to Chicago and my trip back to NY

Delayed by 5 hours and I had to wit in the airport for more than 6+ hours.

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable

I have a gluten allergy so did have any food
