actually Northwest should be either firing the person who wrote the code for them OR they should be getting a MASSIVE refund from the outsourced corporation.
If you take a look at the, uh, fine performance of Northwest Airlines, heh, well, they're lucky to be able to afford the paper to print the passes on in the first place. Things are pretty rough for Northwest.
Not sure what real security weakness that exposes, though. From what I can tell, the purpose of restricting the terminal to ticketed passengers was to reduce the number of people going through the security checkpoint. Unless so many people print phony boarding passes as to flood the checkpoints, I don't see the problem.
