There's still a couple 99s and 1900s operating out of BFI, BLI is a 1900 run out of BFI. GEG is mainly a Brasilia base with a single 1900 I think.

The 99 at SEA is I believe a DHL run operating SEA-GEG M-F with potential to be called to fly Sat out of BFI.

All the bases up there get covered by PDX reserve if anything happens.
