Allow me to elaborate, ~2.5'ish years ago the junior FO in PDX had been with the company something like 4-5 years. It's doubtful you'll get much sympathy for "interviewing a year ago".

In all seriousness there are so many moving pieces anyone who tells you something staffing wise is "going to happen next month" is just guessing. Just because more flights are happening out of PDX does not mean they'll be flown by PDX crews. High reserve levels suggest the base could be already staffed. SEA was overstaffed a few months back and they reduced the total compliment by something like 20-30 bodies a month after awarding a ton of people the domicile. That should tell you how fluid this entire thing is.
