The baseline is to have everything happen as expected. That is what happened with the small exception that climate control in the aircraft sss not turned on when boarding started making the aircraft very hot. All in all great experience!

10.0 Wonderful

Caroline, Oct 2026

On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.

4.0 Mediocre

Alex, Oct 2026

My bag was open when I got to Portland and all my clothes were wet and my parking pass was wet

10.0 Wonderful

Marcia, Oct 2026

I liked one of the movies ( which I'm not a movie person" but this was so funny. I had to keep my laughter out loud to a muffle.! I felt too squished in my window seat and the man next to me was not big and bulky or heavy. I like the option of only two seats together. It made it much better for bathroom breaks.

6.0 Okay
