Oh, so you think that Kayak will actually be charging me for the ticket -- that would be easy. I got the impression that Kayak would be storing my credit card details and automatically fill out the appropriate airline's website forms in the background... which would require storing all of my credit card details with reversible encryption. Also, according to my processor there is no interchange fee difference for using CVV or not. There is a financial incentive for address verification, but not CVV. Maybe this varies by processor.
