My mom and I have booked a domestic ticket in France on Air Liberte. As I am entitled to get the teenager discount, so I just purchase a one way ticket. However, as my mom doesn´t qualify, so she has to buy a return (of coz she won´t use the return portion) We are planning to credit the points to the AA account, do u think we will get a bill later on.

We will also have another trip in Europe doing the same thing with a really small regional airline, but the ticket was ticketed in Canada. Now, I start to scare that I will get a huge bill after the trip, as the difference between a one way and return is huge.

Anyone can give me any ideas, I would be really appreciate.
