I'm sorry, Ma'am, we're going to have to confiscate this manuscript

Apparently J.K. Rowling was worried that they wouldn't let her take her manuscript onto an airplane during a heightened security alert. It isn't clear from the story whether this was just her own worries, or whether she actually had to convince airport security to let her take her manuscript with her. But if the latter is true, I wonder if she name-drops herself right away, or tries to get through anonymously first? I can see both pros and cons to saying "I'm J.K. Rowling and this is part of the manuscript for the next Harry Potter book."
