Airline reviews

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Flight crew and flight were good. But it departed two hours late.

They were friendly, efficient and got our bags to us so fast at the end of the flight.

Amazing. They work with my disabilities with such kindness, attention, wnd diligence. They make it easy for those of us who need a little more extra care.

Quick and easy and nice flight with nice flight crew.

We were traveling with four adults two children. The boarding crew helped seed us all together quick flight from Sacramento to Boise, seamless.

I love having assigned seats and being able to check bags at the gate, if needed. Both are super-helpful when traveling with a toddler!!!

Crew and service were great! Boarding was quick and smooth.
