Flying BOS-CLT last week, and the flight went from J6 at T-100 to J1 at T-24, and as an EXP I wasn't upgraded. At the gate, I was something like #7 or #8 with 28 people on the list. I had an exit row and an empty middle seat next to me, so it was a perfectly fine flight, but holy smokes!

My return CLT-BOS cleared at T-2 days
