interesting.
I have noticed no difference in CPU success depending on subsidiary fleet, either in advance or battlefield. The only flight last year for which I was the sole recipient of an at-gate CPU was on sCO SFO-IAH. And I've ended up failing at #1 on sUA flights.
I also don't buy the theory that future bookings have any bearing on upgrade success.
