It turns out there are a lot of very out-of-the-way places in the world that you can get to by airplane, and for many such points A and B you need more than three flight segments to do so.
A couple of examples pulled from our current flight schedule database:
1. To fly between Tenerife, Canary Islands (TFN) and Canberra, Australia (CBR) requires a minimum of four flight segments.
2. Of all places with passenger service, the points that require the most flights to fly between are Playon Chico, Panama (PYC) and Aniwa, Vanuatu (AWD). These two points require a minimum of 10 flight segments to fly between. Even our software with the default settings is unfortunately unable to piece this one together. Since many of the required flights do not depart every day, it requires over 11 days to do it!
