Question about standby LAX-IAD
I am holding a confirmed seat on a LAX-IAD flight for Sept. 2 and would like to standby for an earlier flight in order to have more time before our international connection at IAD. I would like to get on UA#950. At the present time, UA doesn't seem to be selling "Y" seats. But they have plenty (10+) Business seats available. Should I expect to be able to standby in this situation?
