It's definitely more sleazy and fraudulent than getting a credit card just for the SUB. There's nothing in the T&Cs on your credit card, or SUB, that requires you to keep spending on it (and they certainly could make that part of the T&Cs if they wanted). There
is something in the T&Cs of just about every airline prohibiting you from booking tickets you have no intention of taking.
That said, I have booked an award ticket in the past just for a joke, and then had the audacity to call to get my miles refunded, so I definitely can't judge here
Like others said, definitely don't make a habit out of doing this, because the airlines will care (far more than AMEX) that you're messing with their inventory.
