This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Good seats in Main cabin, excellent service and excellent landing

Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

On time flight. Seat comfort could be better in the Comfort section.

My only complaint on any flight is meals but your gnocchi was good. The worst is breakfast. I can’t understand why you don’t just serve something simple like yogurt, fruit and a muffin or cinnamon roll.

The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good
