Aircraft without problems that leave on time, not 2 hours late with last minute gate changes across the terminal

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

Delta flight was on time, seats were comfortable, and crew was nice.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Flight was good- arrived early ! But ticketing with Underpricer and Kayak was poor at best- unnessacarily difficult due to how the ticket were issued

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The boarding and flight announcements need to be honest and accurate. These were not. While flight delays cannot be avoided, please. be honest with the passengers in informing us about the timing of the delays. Deceptive delay times is not good business. Deceptive and/or grossly inaccurate boarding times are not good business either.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

I have never been assaulted they way I was today in Charlotte - shame on American

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.
