|Jun 2026Everything about the flight timing was perfect. The plane was clean and comfortable. The only aggravation is no access to phone charging or complementary food/drink on a cross-country trip. There were no entertainment options, so I'm not sure how I'm supposed to evaluate that on a survey. It's a discount carrier, I get it, but other options are flying the same route with better depart/arrival times that offer these options.

|Jun 2026Amazing the only thing I would change is the price gouging. They do for the checked bag or the carry on bag. It's a little absurd. I'm already paying them $500. And I can't take a carry on?!

|May 2026Great!

|Apr 2026After waiting more than 6 hours our flight was delayed until the next day. The flight was extremely uncomfortable. Like riding on hard plastic lawn chairs in the sky.
4.0
|Feb 2026I appreciate the low cost but the seating is ridiculous. So packed it feels dangerous. Actually it was so bad today, I'm going to look for another airline next time I fly.
