Hi,

I'm about to purchase a ticket to BKK on UA, but I'd like to make sure that the flights/dates I'm taking have XC (or O) availibity. So that I can use a SWU to upgrade from Economy to Business.

I'm trying to search it on UAL.com (by dummy reservation with expert mode), but XC is not part of the shown list. The award reservation doesn't work either since award is all full on those flights/dates. The flyaow (used to show) doesn't work for me (probably I went to a wrong site or did something wrong).

Any other easy methods (than calling UAL) to check bucket availibity of those?

PS. My intended flights are LAX-NRT(891 on 12/23), NRT-BKK (881 on 12/24), BKK-NRT (882 on 1/8) and NRT-SFO (852 on 1/8). If any of you have an easy access, and can look up for me, that'd be appreciated.
