My experience with a chartered jet, even post-9/11, is you get to just walk on, so it's not like they had to get there early to pass through security, the security of a non-busy airport at that. But, I would assume they would still want them all there and accounted for well before take-off.
I don't know. I could see Daniel, but I'd be disappointed in Bronco if he held JJ out of this game.
