It's also quite easy to "print" (save) a boarding pass in Adobe Acrobat format (if you have the full version) and annotate the flight(s), dates and time(s)... any boarding pass can be manipulated for improper use. I thought about that once when I wanted to meet a friend at a gate, but thought on the oft chance I'd get an eagle-eyed TSA agent. So, I pussed and didn't do it. There were times I also thought about doing that for some free bevvies on a slow night at the SEA Boardroom, but....guess I wasn't that desperate for a free cocktail after all.

Oh, yeah, the boarding the wrong plane thing.....anyway, I'm settling in on a SEA-LAX flight in 2D last year and this adorable blonde in a "rather attractive" outfit boards and announces that she's in 2F....I'm thinking, ah, now this sure beats the standard issue seatmate! Just as I'm beginning to think this is gonna be a great flight, along comes the FA doing a boarding pass check as a gentleman waits behind her....seems the blonde was supposed to be on a SEA-LAS flight, so the FA escorted her off the plane. My new seatmate and I got a few yucks out of the ensuing blonde jokes...

I never have figured out how a pax can board the wrong flight when the scanners are working at the gate to prevent just that (among other things).
