There are other firms that offer this type of service as well. Some of them may also work with some of the 15 states that OPC doesn't cover.
But do the double miles offers (UA Visa and SPG AmEx) apply to the payment of state taxes, or only to federal ones? If there are not to be double miles for use of the card to pay, then the miles will come at a cost of 2 cpm or more, which is not too appealing, at least to me. (Are other card issuers besides UA Visa and SPG AmEx offering double miles or other special incentives to use them?)
