Alaska Airlines Mileage Plan - On AS website PDX-SNA-PDX seats airport checkin only for may 17/22 ?

I've never had this happen on the AS website before for flights so far out.
Normal or not?
I let my expertflyer subscription lapse otherwise I'd check the loads there
Tks

I checked and it appears MVP/G seats is almost all thats available for those days. There a bunch of MVP/G seats left that will open up at 24 hours so you would be fine making it. Also considering F is completely empty some more seats will open up when MVP/G get their upgrades

I'm not sure whats going on the 17th but 22nd is the Friday of Memorial Day weekend.

During peak travel days, even MVPG seats are gone... ie- thanksgiving and x-mas & SB to destinations like LIH, KOA, MIA, OME ;)
