Pull a fire alarm. Sneak through security or run past the TSA agent falling asleep near the exit of the secured area. Try to open one of those secured doors marked "alarm will sound". There's lots of ways.

Heh “run past the TSA agent” means gunfire is involved. That would definitely mess up an airport (and likely you too).
