Haha, it seems that my idea was not that creative or innovative. Although I think with the system it would still work. Either way I think I will abandon it.

It seems like one of the best way to get miles without flying is to charge business expenses to your personal credit card, then being reimbursed by the company.

But how do you convince suppliers to let you pay your bills with credit card?

Or if you do not have your own company, you also have to convince your managers? Does anyone have some convincing arguments?
