Enforce the one bag rule for carry ons. Don't allow people to have 2 and 3 carry ons. Make baggage gets loaded onto the correct plane. My bag didn't get put onto my last flight so I didn't get it until the next day.

Enforce the one bag rule for carry ons. Don't allow people to have 2 and 3 carry ons. Make baggage gets loaded onto the correct plane. My bag didn't get put onto my last flight so I didn't get it until the next day.

Crew very courteous. Boarding was great. Slow to get baggage at Denver.

the planes were beautiful!! crew was outstanding...flight on time and baggage was quick... can't think of ANYTHING that could have been better. thanks for a great trip!!

The crew the employees were friendly and excellent. There was a problem with the plane and they had workers there immediately working on it. They made sure the people that had immediate connects knew what gates they had to get to and had them leave the plane first. Very thoughtful.

Made us check our carry on,even though there was plenty of room because they didn't check with the flight crew. Also boarding was 40min late, due to the plane being on the wrong side of the airport. Also their app didn't record my tsa precheck

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.

The entire trip from Bellingham to Seattle and from Seattle to Boise, Idaho was very very good and timely

The flights were on time and catching the connecting flight was a breeze. Next time I won't carry such a heavy carry-on without wheels!!

Both flights were delayed, the Bellingham to Seattle flight was delayed so much I nearly missed my connection with a two hour layover to spare. I could have driven to Seattle and back in the amount of time the flight was delayed. Seattle to Bellingham Washington also delayed. Not good.

Staff very helpful and friendly, in flight entertainment poor. Flight left late and thus arrived 20 minutes late to final destination.
