miz - Looks like you are set (almost).

I'm not saying that anyone should wait for the online checkin, <b>but</b>, 2 weeks ago I checked in online 24 hr before our flight on Continental to print online boarding passes. I was able to change our seats online, and in fact got the exit row, which we like because of the extra leg room, even though they did not recline.

I'm not sure if the same applies to USAir.

ok thanks Jed..I will stay on top of this and keep checking my options.
