A Better Passenger Boarding System (BTW, Jetstar Sucks)

TL;DR: The fastest method of loading passengers onto a plane is to group passengers based on the oddness/evenness of their seat row numbers. Board passengers with odd numbered rows through one door, and passengers with even numbered rows through another door.

I went to Melbourne last weekend for GP Melbourne (don’t ask – I lost badly). But I very nearly didn’t get there. My flight was originally at 5pm, so at 2pm, I decided to do a web check-in.

I felt slightly frustrated, but I was short of sleep and felt tired, so I didn’t bother. When it came to boarding however, I was surprised, as Jetstar had changed their boarding method. I thought about it for a while and then I tweeted about what I thought to be Jetstar’s inefficient boarding method:

I fell asleep after the first few lines of code of course, but on my trip back from Melbourne, I completed the code but never actually ran it… until today. You see, I didn’t think about it for a while until yesterday and today, when I received a number of Twitter mentions. I hadn’t checked my twitter mentions earlier, and hadn’t noticed Jetstar actually replied to my tweet:
