[Butch Cassidy Slept Here]

Just because some a-hole somewhere may have told someone that their car seat could not go on, really has nothing to do with someone wanting to preboard.

Really? So, they wanted to pre-board because they wanted to admire the paint job on the jetway walls?? Or, they had a direct connection to "Scotty," in the engine room, and their car seat was going to be "beamed" onboard the plane??
Earth to Jetliner: Are you there??
