i've been reading these threads, expecting to have to wait for the battlefield upgrade for my DCA >>> IAH flight y'day, with 7 open up to T - 24 on a 738. i was upgraded right at OLCI at that time, with the remaining seats being taken. the upgrade waitlist was only 10 deep at its peak.

i'll see what it's like on my friday flight home on a 737 currently with 9 open but seemingly a totally full Y cabin. i'm on an H fare so we'll see if that makes a difference..
