Premium travel has no value for me and I'm concerned that it might be like crack cocaine is for some folks.
The fact that I could be getting a product that somebody values at $10000 for say $1500 plus miles is worthless to me, since I value that product at a much lower amount.
I would rather get $700 for free than get a supposed $10000 "value" for $1500.
The trip I value; the upgrade I don't.
