Ted Kennedy was denied a seat on a flight because he is on a terrorist watch list:

It turned out that Kennedy was on the Transportation Security Administration's "watch list" of suspicious people who might be linked to terrorism.

Kennedy, relating the story to his colleagues and members of the bipartisan 9/11 Commission this past week, asked, "How in the world are average Americans going to be treated if they get on that list?"

There were some jokes about "Irish terrorist" and Republican vengeance against a liberal icon, but nobody had an acceptable answer.
Is the war on terrorism really martial law?
