Merchant credit card fees are at most 3%. I doubt airlines pocket a big portion of their branded cards’ fees as profit, and I would bet they get less than even 1%. The vast majority of the fee probably goes to the banks and card networks.
Even assuming 1%, for an airline to lose $10,000 in profit, you would have to be spending $10,000 / 0.01 = $1M per year on that credit card.
And if you are spending a minimum of $1M on your credit card per year, I doubt you are spending your time optimizing “miles” and “points”.
I assume there are lots of smart people working at airlines that can work out which of their policies earn and lose money, especially now that all the competition is minimal except on the most popular routes.
