What year is this again?

So I just booked a ticket to Ireland for the week in July between my last day at school and my flight home, and the e-mail notice informed me that my ticket would be mailed to my mother's address in Chicago, which I'd given them as my credit card billing address.

A paper ticket? Who does that?

(Updated 5-15-2007: And then they sent me an e-ticket after all. I'm confused.)
