I don't think those are daily flights though. They operate only a couple times a week during the high travel season.

phase III
 

Is phase III the opening of a domicile? I think it might be

As I've said before, find a classified ad for flight attendant hiring in a SFO or LAX newspaper and you'll have your west coast base. 99% of our flight attendants will bail before they ever set foot in a crewroom out west.

Did LGA have stores clerks or quality control inspectors? I can't remember. Those positions are now listed on the careers site.
And I agree that most would bail

Does anyone know how far out they've filled classes? How long have people been waiting from their initial offer to starting class?

I don't think they did. But given LGA's relative closeness to our bases and SDF, it may not have been as logistically necessary as it is in LAX. Just because we store parts somewhere doesn't really mean much more than a place to keep some common parts to maintain the operation.

It's on DeltaNet / TravelNet now, we begin daily non-stop flights between LAX - FCA and LAX - MSO on December 21. Also, looks like Phase II of the west coast expansion is more official than just showing up on TravelNet:

Delta adding flights from Seattle to West Coast cities - seattlepi.com

Yep. One November class that was just topped off, a few for Dec 5 and Dec 19. It's on.

Well look at that! I am almost positive I looked that flight up in the past and it said operated by SkyWest. That link you posted is almost identical to an article on Deltanet that shows an increase in service to Seattle from LAX, SFO & LAS. LAX - SEA (on some) and SFO - SEA show Compass but LAS - SEA still shows SkyWest. Maybe that one will change too?

Gonna be gettin my rainman on if that happens! Look out, Dolla Dolla Bills!
