I believe you originally wrote into the Gurus as I recall replying to this or a very similar email. Credit cards, unlike debit cards DO care about satisfaction with the product or services. I do not know why Reg Z wouldn't apply and would want an explanation from those internally who say it doesn't. To the idea that it's a nonrefundable transaction, that actually means if your customer cancelled it's nonrefundable. The travel agent is not allowed to steal the money by saying it's nonrefundable. V/MC should be able to go back on whoever received the funds, but those rules are more a chargeback issue and I am not well versed in those rules.
My opinions are not necessarily my employers.
