Standby on UA using Aeroplan Miles
I would like to use some of my AC Aeroplan Miles for an upcoming UA Itinerary (this weekend!) AC is showing limited availability on UA for ORD-SFO, but it seems as though the flights are wide open for REV travel.
If I book an itinerary w/ a connection, will UA allow me to standby using Aeroplan miles? Thanks in advance for your suggestions.
