I know I should do a search, but its already one of THOSE weeks.

I'm on a 6 pm flight tomorrow. Right now the earlier flight is open (thanks to KVS, I know this).

If I check in tonight on line at 6 pm can I
a) request the standby (and confirm with the $25 fee waived as a 1K)
b) resubmit my upgrade request.

Thanks.
