Justin Bieber -- Super Bowl Bound

Justin Bieber isn't letting 3 criminal investigations in 2 countries cramp his style ... he's just gone wheels up -- with the Super Bowl as the final destination ... TMZ has learned.

Bieber chartered a private jet Friday from Canada for the big game on Sunday. He's in the air right now.

We're told Justin's planning to attend some pre-game parties, and he brought along some friends for the ride ... and his dad.
