Are others finding E+ availability in short supply? On my SFO-IAD flight I will be in the back of the bus because the plane had nothing in E+. I looked at multiple flights and found pretty much everything sold out. I've never had that happen before. I booked the ticket 3 weeks out. Maybe it's just because it's the last week in August. Thoughts? Experiences?

It's a real bummer to be sitting in E- Upgrade seems pretty unlikely to clear. I haven't sat in E- in several years.... Gulp.
