Would it be evil to use my Avion points to purchase tickets to go home for Christmas and then my mom pays me back for the tickets because she’s been insisting on buying them and I make a profit ?
Or….have her buy the ticket you save the points to take yourself on a trip somewhere you never been
I’ve also thought about that, but I’m bringing my boyfriend and she has an offer offered to pay for him only me 
But also, I just upgraded my credit card which gave me an extra 40,000 points which is two round trips so it’s not like I’m losing any of my original points in the first place I’m actually gaining 10,000 if you think about it 
Use your points for him. Have her pay for you.
