In most cases, anyone here who is advocating for a spend-based system does not spend their own money. If you want a spend based system, lets reward those who actually spend!

Respect to those who earn 1K/GS on their own (or their own business's) dime. Those who fly on someone else's dime - you would be nowhere if the rewards actually went to who pays for the ticket.

I would imagine for hotels it would be much easier to implement than an airline scheme.
