I just bought four tickets to Hawaii on separate PNRs, but I chose them because the outbound flight was R4 and the inbound was R5. Then, I began processing the upgrades using regionals/globals and after I got to the third ticket the remaining space disappeared. Of course, it could be that someone scooped up the remaining seat on the outbound and the two seats on the return, but those flights are 6 months from now and the R availability was the same for the past few weeks (so, possible but seems like an odd coincidence).

My question is this: did I somehow trigger something in United's computer system where it saw three upgrade seats redeemed in close succession and pulled the rest until inventory management or someone can review the loads? Right now the system won't even let me process the fourth and final ticket to be on a waitlist--it just gives me an error message. That further stokes my suspicion that this is maybe a website issue...

Thanks in advance for any insights you all may have.

Update... About 10 minutes later and the flights are R1 and R2 now as they should be. Maybe this answers my question; confirming that I did trigger something in their system. Has anyone noticed this before?
