PQP based on original or updated fare price?
If I make a change using the waiver, will I receive PQP/M based on the original fare price or the price of the new ticket? I am wondering b/c fare difference is waived what is stopping me from changing my original flight that is earning me 1000 PQP to the highest fare class I can find which would earn me around 15000? I have already confirmed that I can make the ticket change for free so I am just wondering in regard to PQP. Thank you.
