Transporting prisoners on a commercial flight?

Someone even says, "Why don't they send hijackers by car or train?" It's a paraphrase, but a good point. I'll tell you this: the FBI really gets trashed in films, doesn't it? Any good films with the FBI out there?

John Mark Karr (murder suspect for Jon Benet Ramsey) was transported from Thailand to LAX via a commercial flight, escorted by two US agents...and they flew him in biz class to boot.

I was on an airline flight with a prisoner. I can't say that it was federal, though. In the waiting lounge, the man had ugly brown pants, a buttoned-up brown tweed jacket, and scruffy hair and beard. He kept his hands in the jacket pockets at all times - because underneath the jacket the pockets were torn out and he was handcuffed. The officer escorting him was better dressed. When the time came to board the plane, the officer kind of helped the prisoner up by the elbow while his hands stayed in the pockets. Anyone breezing through the terminal wouldn't notice, but when you were sitting next to them it was pretty obvious.
