I have some question :
Should we buy cargo slots ?
Does cargo planes bring us so much money ?
Yes, cargo planes n slots are worth investing. Atleast at prg, iad, mct n lej.
Cargo stands cost you more, that is for sure.
However you don’t have to purchase more services than passenger flights, so that is up to you.
The revenue for the same aircraft with both passenger and cargo variant does not come with significant difference.
if you have your own cargo plane it will make you a lot of money
