So very confused by this situation. I am booked on flights in July SAN-LAX-PVG-LAX-SAN. V class and requested upgrades using GPUs. Used the united.com website and requested tickets that were eligible for upgrades and, with the exception of SAN-LAX, each leg is waitlisted. That seemed normal to me as only a few R class seats are released at a time, so booked the flights. There is no one, and I mean no one in BF, and there are only two other Y seats sold on the LAX-PVG-LAX flights. I have never before experienced that no R class was available when no seats have been sold. Is this normal? I am used to not getting my GPUs, but thought it was because the R class seats had been allocated, not because they were never allocated. Thank you for any insight that can be provided.
