Hi all,

I have a W-fare ticket for a TATL flight for next fall (Sept 2016) that had R space at booking. I applied a GPU and got the "Upgrade Confirmed".

This morning, I went to go check my itinerary on my mobile device and saw that it said "Upgrade Waitlisted." I panicked as I had deliberately booked this flight knowing there was open R space.

I opened a web browser on my laptop and went to united.com to check everything. The itinerary said there was a change in the schedule and that I needed to acknowledge and accept it. The change itself was very minor - the flight was changed to arrive a few minutes earlier. I accepted the change and sure enough, I went back to "Upgrade Confirmed" and I was relieved.

Question - is this just a quirk of the system? Was I in danger of losing my upgrade? Will I be in danger of losing my upgrade going forward?

Thanks in advance.
