Hello Milepoint! I feel horrible for asking this question because it seems so simple, but I haven't really found an answer to this anywhere after extensive research.. Maybe you could help me out? I'm an AAdvantage member and I'm trying to find flights for a multi-city itinerary next summer. London to Tokyo and Seoul to London. If I search for OneWorld flights with Hipmunk I get a lot of results no official OneWorld airline booking system would show, and the Hipmunk tickets seem to be cheaper as well. Now, how do I ensure that the booking class is valid for miles? As I understand it, it could show me flights from travel agencies that sell tickets with special fare classes which might not give me a single mile.. Or am I mistaken? Thanks for your help!
