Okay|Nov 2025

The exit row seats without a seat in front are great for leg room but don’t have a fold out entertainment console so you’re forced to use the screen several feet in front of you (there is, at least, a remote). Best to bring a tablet loaded with entertainment or a book.

8.0

Very good|Nov 2025

The crew was very friendly, but they only came around and offered the better Delta Comfort snacks one time. I thought they would come around more frequently on a 5 hour flight. They did do two beverage services though, which was nice.

10.0

Wonderful|Oct 2025

It's specail being able to fly non-stop from Amsterdam all the way home to Portland, Oregon!

8.0

Very good|Oct 2025

This is always a full flight since it is the connecting route to primary destinations through Atlanta. That said, the crew handles the full load well. Not much more to say, it is a short flight with no in-flight services due to the length.

10.0

Wonderful|Oct 2025

Only negative outcome of this trip was 3 hour delay, but everything else was fine.
