We have always used a NW airlines card - frequent flyer miles, 1 point for every dollar. We are now switching over to the Disney card, the NWA program has become increasingly harder to get FF tickets to where we want to go at the times we want to go.
For several years we have put everything on our reward card, food, gas, house payment, phone bills, car insurance payments, etc and also treat it like a check and pay it off every month so there are no interest charges. We have even decided to put my DD fall college tuition on the Disney card then pay it off with an equity loan check. At est of 13K a year for tuition that should give us some extra disney dollars.
Another advantage to putting everything on a CC is the shock you get of how much you spend in a year on just stuff. It really makes you think.
