It's weird how southwest does it but a professor did a study on different ways to board a plane and the way most airlines do it is actually the least efficient southwests way was actually the best way out of any of the airlines, however still not the most efficient. Just a little nerdy FYI for you
#makingameme RT @broox: Southwest boarding is weird. And creepy. And now I know lacks even the loosest attachment to anything like reality.
