Commuter hotels are at least codified in a MOU that can be terminated by either the company or union with 60 days notice. The positive space commutes seem to be on an as required basis. When staffing is tight, as it is now, they seem to be going out of their way to make sure people show and pickup flights. This the inverse of how it was even just a year ago.
I’d say you have a 99 percent chance of getting Seattle as a new hire as long as hiring continues as is.
