According to the rules instant ups are actually higher priority than GPUs at 5 days out.
- Premier members on eligible Y- and B-class fares, as well as Premier 1K members on M-class fares: Instant upgrades that weren't confirmed in advance, sorted by fare class, then Premier status
- All travelers on waitlisted Global Premier Upgrades, Regional Premier Upgrades, and MileagePlus Upgrade Awards: Sorted by Premier status of the redeeming account, then fare class and time of request
- All remaining Premier members using Complimentary Premier Upgrades**: Sorted by Premier status, then fare class and award travel***
Best option is to set an EF alert for P/PN space opening up and then calling in to have the instant up forced through.
