You want BOTH no interest AND no transfer fee AND miles? Two of those three is hard enough, typically only through a few smaller airlines, like Midwest that someone else already posted and Frontier:

and the transfer fee is limited to $50 max in the latter case (btw, the Frontier card is also from Juniper, who also does Best Western similarly, so it seems like almost all these offers where you earn miles on balance transfers come from Juniper). But I don't know of anyone who gives miles with a no-transaction-fee balance transfer and then makes it 0% on top of that. The banks have to make money SOMEHOW, don't they ?
