Flying on 187 BOS - ORD tomorrow... normally my upgrades on my Boston runs clears several days out, often at T-100 no matter when I booked. This time, I booked in December and no upgrade to be had yet. Cabin is showing F7 A7 and was F7 earlier in the week when the upgrade window opened.
On my outbound on Saturday, 186, I cleared about T-6. Even with the cabin showing F7 A6 for most of the week leading up to the flight.
As an EXP booking back in late December, if I'm not at the top of the list I'd be damn surprised. Just don't understand the reasoning in holding back the seats. Everything BOS - ORD tomorrow is F5+ except for one F2 (6am departure).
