Thanks for replies so far. As far as corp travel policy, I believe they pick the airlines depending on whatever algorithm they have and they probably use all the major ones at different times and I dont get much of a choice so i will be spread thin. I'll be taking probably around 30 to 40 round trip flights per year.

I do have a specific question:

Are there Hotel Points cards that work like Airfare FF Points cards where it doesnt matter how I pay for the hotel stay, I can just get points on my rewards cards anyway? Or do all Hotel Points Cards require that I make the purchase on a specific Hotel-Branded CC?
