Seats were lousy. Right next to the restrooms

Feb 28, 2020

I do not think that I should have to pay to sit together. I Think that it should be a courtesy to assign two people traveling together seats together. I object to paying more.

Feb 21, 2020

Wasn't impressed by anything on these flights. Just happy they took-off and landed on time. For you that's an accomplishment.
