I am traveling from BKK to SFO on UA838 this coming Sunday 06/16. I am booked in S class and can't apply a Global Premier Upgrade through NRT due to the low booking class. As I want to rest, I have requested a copay upgrade (30000 miles and USD 600).

Equally, I am returning from SFO on 06/22 to BKK in W and am wait listed for Global Premier Upgrade.

I was wondering if there is a chance for these upgrades to clear? Anyone on here with some insight to the system or similar experiences?

My status is United 1K

Many thanks for comments/opinions. I can't find any info on wait list status on the United website despite signing up for the expert features.

Many thanks
