I always travel Horizon run by Alaska from Bellingham WA. Alaska from Seattle to Spokane is usually a larger plane as it continues on further east. Each flight is 60 minutes or less.

Now that Southwest doesn't fly in and out of Bellingham Washington there are no good options to Seattle. You're best off driving or getting a shuttle, it's much more likely you'll get to Seattle near the time you think you will. Flying is just not a dependable option anymore.

Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

The kiosk for check in/bag check in. I liked the older version where you did everything on the kiosk (check in and bag tags). This time I needed to use my phone to check in and then scan the ticket from my phone to complete the bag tags. I didn't care for this new method. The older method was simpler.

Weather caused delays, but since I was in no hurry I asked to reschedule for any other day to make room for anyone in need of keeping their schedule. Alaska accommodated my request with an extra bonus - with a credit to my account for another day…. Always had great experience with the Alaska folks.

Overall it was a good flight. No issues. Alaska Airlines is always my first choice.

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.
