I find flying long haul on VATSIM a good companion when I had to work overnight with my paper on my loptop. The following are some of my favorite medium to long haul routes.
RPLL-YSSY-YMML-RPLL
RPLL-KSFO-RPLL
RPLL-CYVR-RPLL
RPLL-KLAX-RPLL
RPLL-VTBS-RPLL
RPLL-VHHH-RPLL
Currently I have logged 1057 hrs of Carrier activity on VATSIM network.
