What a weird terminal design. Ground-level gates? 737's are depicted, but even with regional a/c a two-floor terminal should work fine. The beautiful two-level, 4-gate terminal in Bismarck, ND is a good example of a well-designed, easily expandable small-airport terminal . Much better design than what's depicted here.
Only two gates? I wonder if it was harder to defeat NIMBY's than expected, and by going small, they may have minimized legal problems.
Best wishes to PAE and Propeller Airports in developing this airport. If I lived north of Seattle, I'd sure like the prospect of having PAE as an option.
There is no public funding for this project, so it's a speculative venture on Propeller Investment's part. As such, it appears they have kept the design pretty simple and low cost. There is a chance it won't draw the traffic they hope for from nearby SeaTac and Bellingham. Bismark, in contrast, has no nearby competition that I'm aware of, so it makes more sense to invest in a design for the long term.
If Paine Field turns out to be popular with travelers, I could very easily see a completely new terminal being built 15+ years from now to replace it, either starting adjacent to it and then growing from there by displacing nearby businesses and hangars, or on the undeveloped west side of Paine Field, which has better highway access anyways.
Driving down to Seattle this weekend, might swing by to see exactly where the terminal is going to be located. Exciting and interesting for PAE.
I don't think you'll see much right now except pavement torn up near the tower. It's arguably not worth going out of your way for...unless you need an excuse to go take the nearby Boeing tour or visit one of the three historical aircraft collections at Paine Field (Flying Heritage Collection, Historic Flight Foundation, or Museum of Flight Restoration Center).
So is AS currently the only airline with definite plans to serve PAE?
So far, yes. The terminal developer claims they have promising talks going on with multiple other airlines. Who knows what that really means, but like other posters, I could see Delta being interested, and Allegiant has in the past expressed a desire to flight from PAE.
The crowding at SEA is probably most acute for AS, though, so from that perspective this makes the most sense for them. The last two AS flights I've taken into SEA have deplaned at remote stands, because they're out of gates. They also serve a very large proportion of the Puget Sound business travel market, no shortage of which (probably 1/5th, if not more) is closer to PAE than to SEA.
