Lots of changes to this policy since I last used it. Just want to double check to be sure on a couple of things before making some bookings...

1) Would I have to pay a fare difference to move a flight to a different day if the same booking class is available? I'm looking at a flight which I may have to move forward. There's an advance purchase requirement on it. If I was to book this ticket then need to move the date closer (and early than the advance requirement), then will I have to pay a difference in fare (even if there is availability in the same booking class and assuming no cancellations/schedule changes by QR)? My read is that I'll have to pay.

2) Can I technically book a return, fly one way, get the return leg refunded to my original method of payment? It seems to be that this is possible?

Appreciate the help!
