So a friend is moving to NZ - and will occasionally fly from NZ to YYZ...maybe 2-3x per year?

They are not current part of a FF program - in fact flew a month ago but didn't credit the miles anywhere. They flew in Y - AKL-LAX-YYZ - QF for the first segment and AC on 2nd. I imagine they got there somehow too but have no idea what flights they took.

1. Is it still possible to credit these miles to a program?

2. Being NZ based - within OW or *A what is a better program for infrequent travelling?

3. If OW - it used to be AA seemed the better choice - but that credit card use in NZ would make QF somewhat more palatable. What QF credit card is available in NZ? Is there an AA credit card at all in NZ?

4. They would like to be able to redeem for upgrades to business class for a parent to travel more comfortably to visit them from YYZ - AKL (lie-flat seats would be important). Probably not a full award ticket but upgrade from Y to J. What is the best program for that? Looks like QF even offers upgrades from discount economy to business class.

Thanks for your help!
