We can definitely see that contest coming up soon. With this contest we thought sub-$2k would be a huge stretch, but the flight hackers seemed to manage it with ease. For business, we can't imagine it being less than $5-6k, but we'll see. Sub-$5k would be amazing.
I would also be curious with a maximum of say 1 or 2 month timeframe. If I was actually curious in an "around the world" trip, I don't think I'd want to stay 11 weeks in Germany, ha.
