Can you check-in online with $25 confirmed standby?
I'm on Sunday's 3 p.m. "direct" BOS-PDX (stop in SFO) and would like to take the 8 a.m. BOS-SFO instead. I might be willing to pay the $25 for a confirmed change (at 4 a.m., yikes) if after confirming the change from home I can get to online checkin and pick a decent seat; it's worth $25 to not be stuck in E- or middle for a transcon, which seems more likely if I do "regular" standby.
Also, will phone agents (probably Indian agents due to the time-of-day involved) do a confirmed change for just the BOS-SFO part, or do they have to get all the way to PDX? All of the SFO-PDX flights are showing F0 Y0 for the day, so I doubt they'd be willing to confirm a change. The BOS-SFO I want is showing F3 Y9 ... H9 so should be OK.
