I certainly wouldn't. It's not a huge base anyway, and it doesn't cost them much to run it.... Delta provides our line mx and they're gonna be there whether we are or not, etc. I doubt rent on the crew room is very much... There is a lot of gate space to overnight A/C that just doesn't exist elsewhere. And as for crews, it is a reasonably small base - 51 FOs vs 290 in LAX. They still build plenty of Seattle flying out of LAX, it's conceivable that if SEA had a reduction in block hours they would stop building SEA trips out of LA, for example, before looking into building trips elsewhere... trips can be built out of anywhere, essentially, to a point. Also when you look at DL's seattle strategy what you see right now is right-sizing to the loads. For example they have 50 seat 76 seat 110 seat (the 717) and more (737+). On a route like SEA-LAS you may see the somewhat empty tuesday noon flight as a 50 seat Skywest flight, the 76 seat friday morning flight as a 76 seat Compass flight, and the super packed friday night on either the 737 or a lot of 717 sections. With their plans for SEA, bringing the 190 online (probably 99 seats like the American config)... well a lot of people think the 717s will go back East, they'll retire some of the old mad dogs over there, and the 190 would just slot right in. We'll find out in 2Q 2017 when they come online... til then it's all speculation. I don't think we're positioned any worse than anybody else... but maybe that's just wishful thinking. I will say Compass loves to open and close bases, but DL is pretty committed to Seattle and I wouldn't assume anything or make career decisions based on E190 speculation. Still better to be a super senior FO at Compass commuting to LA than a reserve in base, but that is my opinion, and I'm sure about a million people are about to disagree with me as we do every time this same thread pops up..
