Thank You Network. It's a home-grown points program from Citibank.

I've never hoarded anything up to the million mark or even close. Right now, I'm sitting on 500k Marriott and it has me a bit itchy. 200k HH, 100k SPG as well. In the airline world, I have about 440k AA and 240k UA, plus four or five WN award tix that I have earned through Hertz.

And I'm a bit of a noob to the Thank You Network, with about 60k there. Yes, I realize I missed out on some outstanding awards in the past, but I figure TYN can still function as a 4 to 6 percent rebate card on a subset of my spending, so that makes it a might complement to SPG Amex.
