On time (in fact, early). Easy boarding and getting off.

they took my carryon at the gate for free. Everything went smoothly.

It was delayed twice and they still want $8 for wifi so i had to sit for an hour.

I rated the food and entertainment as poor due to the fact the flights were short in duration and no food serves or entertainment provided.

It was awful. We experienced turbulence for nearly the whole flight. Then when I picked up my luggage, two of the wheels were torn off. Worst flight ever!!

I like the short flight to Seattle and San Francisco. The boarding was fairly easy and the flight was as to be expected. The in-flight entertainment could be improved with wifi options. Paying $8 and then losing internet access and being told that flight attendants didn't want to serve beverages and snacks on board was disappointing because they didn't want to move a cart up and down the aisle blaming it on air turbulence which wasn't a problem.

Not great. The flight was delayed, then when we were on the plane we spent over an hour taxiing before take off. We arrived very late and it took a long time for the luggage to arrive. I wish you all Happy Holidays though.

It was comfortable, the food was mediocre. Tasted like microwaved food.

My flight was delayed. But it was during holidays so you kind of expect things like that to happen. I am not a frequently flyer so I am OK with that. But none the less, once the flight started, it seemed to me like it went fast. 😊

The planes were clean! The crew was good The boarding in Seattle was not good because the accent of the woman and the low volume of the speaker made it impossible to hear.
