This flight was straightforward and without difficulty. Service was OK, but I continue to be underwhelmed by level of attention given to Sky Priority passengers.

This flight was straightforward and without difficulty. Service was OK, but I continue to be underwhelmed by level of attention given to Sky Priority passengers.

It would’ve been nice for all that money to have a more substantial snack for free. I remember once upon a time getting a very nice turkey sandwich with Swiss cheese on whole wheat bread for no charge along with a drink. I guess those days are gone. it’s a little insulting being given a cookie or a bag of baked chips Going forward I’ll just bring my own.

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

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

The flight was an hour and a half late departing which was inconvenient

The flight was great. The gate location was way to far away!!!

The flight attendant in first class was beyond rude and didn't care at all about her job. AND the gate agent was even worse than the flight attendant for rudeness. She was awful.

Movie selection was meh. Food was great. Crew as always great. I paid for premium because that’s the only way not to feel like a sardine. That’s how economy should be imo. Sadly passengers have to pay an extra $1000 to get what they should at base price but that’s all airlines. The airline industry in general treats passengers as cargo.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

We didn't take off until an hour after we boarded.

Wish they had the seat-back video screens for watching movies or playing games.

Very good but wish they had the seat-back video screens for movies & games

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

This flight never occurred because AA couldn’t get their act together.

During service there was a garbage/beverage spill near our seats that never was cleaned up. On a relatively short flight when we’re fortunate enough to actually have in flight movies available, the flight attendants pitching the AADVANTAGE credit card shouldn’t talk for the last 10 minutes of the flight so that we miss the end of the movie.
