Well, after I posted the question about retroactive bonus EQMs, I registered for the promotion even though I very likely won't go within 1000 miles of PAE during the rest of the window.
Today I looked at my EQM count (for a different reason) and the number was several thousand higher than I thought it should be. With a mix of Y and paid J/F fares on AS and partners, and the lack of EQM itemization on the website/app, it's hard to tell what happened. But something happened.
Anybody else have anything to report?
