I just booked 2 tickets from IAD-GVA(w/domestic connections). I booked E+ and today upgraded to R on the outbound leg. To purchase an Upgrade for the return leg I purchased some miles for myself w/Accelerator. I went back in to purchase miles for my husband, I cannot find Accelerator anywhere. The United site stated Accelerator is available whenever you view an existing reservation, I have tried different ways to view his reservation but the Accelerator option never pops up. Any suggestions how to find this or should I just perhaps just wait until tomorrow and see if it appears?
