I'll bet their 757-200s still burn less per seat than their MD80s
I think that might depend on if they go for winglets, and how they configure them.
Keep in mind G4 isn't ETOPS qualified yet (they have to start flying their 757s first and certify with the FAA). It'll take a little while.
So perhaps a BLI-ANC next summer?
What, and compete with the ferry?
Given that between PDX and SEA there's tons of frequency if people make a one-hop out of BLI, I think not.
Given the existence of the "Hollywood North Express" (LAX-YVR) and the one-hops to SEA/PDX, I think AS may be done expanding a lot more at BLI.
