Wouldn't encouraging QF folks to redeem on QR be a good idea for QR though? They get to see how superior the QR J product is plus don't QF have to pay QR for the redemptions?
On the other side, FF seats aren't offered to your prime competitors to draw them away as that's not their purpose. The detriment is that it encourages QF FF customers to boost satisfaction with QF as they have access to the premium products elsewhere while not leaving the QF fold.
As for payment, they're already budgeted for so someone will pay for them anyway. And while QF may be making the payment, it's almost a token amount so not of any significance.
