Don't even think of risking this one. QF has been known to "throw the book" at anyone breaching the
Terms and Conditions of the QFF program.
Keep in mind that if you upgrade a QF flight with QF points eg L to U, and the upgrade is cancelled due to fraudulent use of points, and L class is then fully sold, you may not be able to downgrade on that flight ie you lose the seat.
It's just not worth it.
