The math seems to be off in this article (by 3x). It claims 3,153 Kg CO2 from London to Perth. A Boeing A380 creates 75g per passenger per Km[1]. The distance

  It says return flight, that probably accounts for 2x? The figures are averages taking into account which aircraft models are typically used on flight routes, and the estimated occupancy of seats on board those planes.

  I tried doing the math from Boeing's stated fuel economy for different models of planes and even older 747s which aren't great in terms of fuel economy were coming out 2.5x better than the numbers in this article. I can't figure out how they are coming up with their numbers. Maybe there are lots of empty planes on these routes or something?

  There are a few other aspects to consider, like radiative forcing[1], which add a significant multiplier onto the basic CO2 released from burning the fuel. For one take on calculation of emissions, see how MyClimate (a carbon offsetting service) calculate total CO2 emissions[2].
