Sure Wolverine's claws look badass, but have you ever wondered if he could be charged with carrying a concealed weapon or other charges related to his claws? As it turns out, he'd be ok as long as he didn't get in any unjustified fights -which might be a problem for Logan. That's because according to Vista defense lawyer Peter Liss, the fact that his claws are actually a bodily mutation, not an equipped weapon means he couldn't be accused of carrying a weapon.
Of course, I still don't think they'd let him on a plane like that, so it's fortunate that the X Men have their own jet.
