But a full-fare premier is ahead of 1Ps who are not on full-fares, right?</font>
"Ahead of" only matters when there's a list. Mileage upgrades are done as requested, not listed then prioritized.
So it would be unlikely that a full-fare premier would get a mileage upgrade ahead of a discount-fared 1P. First come, first served, I think.
