Thanks for the input at all. I don't see how there could be fraud since you have to show a picture ID showing that you are the person named on the ticket to get on the plane. Would I be so stupid as to use someone elses credit card to buy a ticket in my own name? I think it would be easy for them to catch me.
But it does point out the problem that irkes me the most about airlines. People have posted saying that they have checked in and NOT had to show the card. Others have had to show it. Why is it that depending on who you get at the airport, some enfore a rule and others don't. I have had one employee tell me that a picture work ID is no good and another took it, no problem. I have had some flight attendants check a carry on small bag in the garmet bag hanging closet and others said it is against the rules, only garmet bags there. I have had some tell me that I could get standby on a Priceline ticket and another said no way.
