Hello , I just registered for asia miles but i'm confused and don't understand how it works. First of all, they say : quote your membership number when you book your flight and present your membership card at check in. But if already bought the ticket and i haven't quote my membership number when i booked the ticket..... can you plz tell me if i can still earn my points ? Can i present my membership card when i check in and still get my points??? Also can i use my card to earn points on my mother and brother's flight tickets?? Or do they need their own card?
