I need to make an 86k purchase in a few days, but my limit is only about 30k (although technically I believe my card has "no preset spending limit".) I'd like to transfer the 86k into my MC account, and then make the purchase. Obviously I want to make sure I'll earn the miles (up to my annual mileage cap) for this transaction.
Some banks may not like you having a negative balance. I would definately call and give them a heads up about what you are doing. I would guess they would be happy with the merchant fee on $86000, but may be suspicious and deny the payment if you overpay your bill by $56000 first.
