Many thank to all here. It's very kind of you all to lend your time to a somebody like me trying to put these pieces together. I think I'll put certain expenses on the United card and all other expenses on the 1.5% cash-back card. I'll balance the expenses until I'm getting just enough miles to buy award tickets in business class for the amount of travel we do.
Why doesn't your business use a 2% cash-back card?
Do you know of any besides American Express? I read there was a Priceline card with 2% cash back so I applied and when it arrived it turned out to be 1%. Apparently there are two versions.
