UPDATE: Actually using this at an airport could get you arrested, so don't.

Chris made a NWA boarding pass generator. All it does it automate the process of changing a few simple lines of HTML provided when NWA gives you a boarding pass online. Chris says it can be used to:

1. Meet your elderly grandparents at the gate
2. 'Upgrade' yourself once on the airplane - by printing another boarding pass for a ticket you're already purchased, only this time, in Business Class.
3. Demonstrate that the TSA Boarding Pass/ID check is useless.

Of course, it's kinda silly if it can be used only on NWA. Their only major hub is Compton.
