I've got an itinerary flying roundtrip on CX from YVR-HKG-XMN. I typically use my Alaska MP FF for CX flights, but the HKG-XMN leg is in CX Dragon which do not accrue miles on ASMP. I noticed that in the CX website, it looks like it allows me to apply different FF#'s by leg, so I was thinking of adding my AA FF on the Dragon legs. Has anyone done this before and had any issues? It's not many miles, so I wouldn't want to cause any complications for a low set of miles.
Thanks.
When I want to do this (which I do from time to time), I change the FF number at the gate for each flight. Request that they reprint your boarding pass, too; so you'll have documentary evidence in case there's a foul-up.
