Yes, we don't have to show our credit cards at the airport anymore.

But the problem here is the fact that someone else's credit card bought this ticket and the names don't match. I run a conference and bought several tickets for faculty members this year. I had to show my credit card to a CS rep at the airport. Although I didn't have to sign a release, she checked my credit card and put notes in the computer file, so the people with the tickets could check in. I don't think any of them have elite status.
