Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

My flight out of Baton Rouge to Atlanta was delayed by a half hour. This got us into Atlanta airport 30 minutes late. I ran through the airport to get to my connecting flight. As I approached the boarding gate, I saw the boarding door was still open and a passenger was being checked in. But when I got to the gate, the boarding agent told me they had already given away my seat and there were no empty seats on that flight. So I had to take a later flight. That has never happened to me before. Very frustrating.

Connection through Atlanta was difficult. Mechanical issue on plane caused a two hour delay. New gate was a mile away.

No WiFi. Comfort plus should have alcohol provided, crew only offered water or tea. Who the heck wants tea?

The flight was delayed and oversold. I volunteered to give up my seat for compensation. Thinking I could get a good night's sleep instead of arriving home at 2 am. It took over an hour to get the new reservation confirmed, three different gate attendants, and two red coats. It took even longer to confirm the overnight hotel, and when I arrived, the line was 45 minutes long, with two people checking in, and at least 15 people slowly, very slowly—no food except frozen convenience food, no coupon for food from airlines. Slept, headed back to the airport, and that flight had an equipment change and a gate change just as they were about to board. It took an additional hour to board as they cleaned the plane from storage.

There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

Good seat comfort ORF to ATL. Bad seat ATL to SEA (terrible lumbar support, hard, ouch)..

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

Enough space,crew was helpful,food was good.The gates are way far especially for travelers with health issues

No enough space plus only allowing one laggage instead of two like other airlines.
