Crediting to diff't programs on single itin, but with separate legs
Traveling LAX to AKL (week long stopover) then to BNE. All on same reservation. Want to credit LAX-AKL to AP and then AKL-BNE to a different freq flyer program. Plan to provide my AP number at LAX. Then, when checking in a week later for the AKL-BNE flight, provide a different freq flyer program's number (prob AC or UA). Anyone had problems with the miles crediting to AP and/or the other program in this scenario?
