One can also do short to medium flights with the 777, there's nothing that stops you from doing that.. :) Unless you really refuse to as it's might not be 100% realistic.. I personally enjoy 1-2hr flights with aircrafts such as 707, 747 and 767 on a regular basis, as I enjoy flying those kind of airplanes but don't have the time to spend 10+hrs on a long haul flight.. :)
