Trying to buy LED-MSY, and the Delta website says I need to have the physical credit card used for the purchase to board the flight!

So if I happen to lose the physical card, I'm stuck, and have to wait until the issuer sends me a replacement?

I've never had this type of treatment before. I don't see how in the world someone could buy a ticket in my name and present my passport to use it, unless this crook had somehow gotten hold of a fake passport in my name - and in which case, there would be a lot more at stake than someone stealing a $300 ticket!

Delta claims that the credit card issuer is requiring this (I'd bet THAT's a lie)!
