Leslie the gate agent was incredibly helpful with helping me get on an earlier flight! I saved several hours of airport time thanks to her, and she made the process easy and quick.

8.0 Very good

Paul, Oct 2026

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

The flight was freezing cold. I had on pants and a sweatshirt, had to wrap up in the blanket provided AND put on my rain coat, and was still chilly. Have never been on such a cold plane.
