Question: What is the fastest you could fly round the world, using only scheduled passenger flights?"
Answer: 44 hours.
I'm now curious if this is true, I would have thought you could do it faster than that. I'm also curious as to what routing would be taken. So I'm throwing down the gauntlet to a.net - find a round the world routing using scheduled flights, that takes less than 44 hours. Time includes time spent waiting for connections.
Your start point can be anywhere you want.
