Airline reviews

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

Flight crew was very cold and stood around a lot talking to each other.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

On time, only a little turbulence, very competent and caring attendants. Clear information.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

On a four hour delayed flight now on seats back end of the plane instead front-

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

Economy seats a bit small but other than that it was all good.
