In the groups experiences, what's the best card for mileage points, skymiles, etc that won't give you the run-a-round....? Delta AMEX, Capital One. I heard of a guy (online) who used his card for the majority of his routine and annual expenses and built up boo coos of points. He even paid his IRS and State taxes as well as his RE taxes with the CC. I don't think he's "bought" a airline ticket in years.....I know the system can work, I just don't know of anyone personally who's doing it.
