|Oct 2026The operation was kind and professional, and I thought it was neat that the pilot shared over the intercom when we were passing over two landmarks - Yosemite and Lake Tahoe -- so we can look at the window.
2.0
|Sep 2026They charge $25 to check in with an agent and the only other option is to install the app, so I installed it just for this one flight. Then the app didn't find my reservation so they sent me to an agent anyway. The agent was unfriendly and printed my boarding pass without tsa pre check, so I had to go through the standard line. Also the flight was delayed two hours.
8.0
|Sep 2026I was traveling with a lap infant and got to TSA only to be turned around saying that something was wrong with my boarding pass. I went to an agent and said nothing was wrong, printed me a board pass and I had to rejoin the line. The when I get to the ticket counter I found out they changed my family seat even though I purchased it prior. I was told I got a refund so I’ll see
2.0
|Jul 2026Flight was delayed a whole day - no compensation on food or drinks. Gate staff gave an older gentleman a hard time about his confusion and concern regarding the overnight delay.
10.0
|Jul 2026Better Food and there was no entertainment . You guys could provide head phones and wifi for the passengers
