i've got another flight coming up next weekend, and pretty much every seat is taken (according to the seat map now)...only window seat left (which i prefer) is 12F. i guess 7 D/E will open at T-24, but i really have a difficult time getting comfortable in an aisle seat...how limited is the recline in row 12? what are the chances that other windows will open up at some point? it's PHL-SFO so i'd like to be as comfortable as possible, and find it easier to sleep up against the window - but not sure how the limited recline will affect that.

as of right now i don't have any assigned seat, all regular economy were taken when i booked the flight...
