I don't know what is use of the cargo plane and is it profitable?
Is the AT2 down for you Friday November 15 2019?
For cargo planes, it is the same as a passenger route. You have to open a cargo facility at the 2 airports. Cargo can make decent regular money, but passengers make more money.
Cargo planes are very profitable, especially the 707-320F. While cargo routes won't beat passenger routes for peak profit, they are stable all year and cheaper to run. Also consider the AN-24 a great option as you can easily fill it on any route.
Cargo routes can make 5000 to 6000K in the early 60's. Passengers make 1000 to 5000K.
What do you think?
