Great airport. Just to add if you need parking the very first lot you encounter is the least expensive at $5 per day. (This is for Port off Bellingham Parking - not other companies) There is a free shuttle and you can pay while waiting for your bags. (If you take your parking slip with you.)

AS has seasonal jet sevice, LAS, HNL, OOG and SEA. That stops at in June and returns I think in November. During the summerand there are just Horizon flights to connect at SEA & PDX.

I flew Allegiant once and the added costs made it more expensive than AS.
