So, i had this doubt for quite a while (as cargo planes sometimes can give a good amount of money), and when the 777 CG was released, i did not know if i should accept the routes for it.
The answer for L is no so don’t accept those right now for M, wait until next update
BRI will have 1 M-cargo slot in next update. Nothing bigger than that (they do not have regular L/XL cargo traffic also IRL).
Also (since i went there a couple of times) they do not operate with 777s or those airplanes
Sometimes specials arrive.
Really? didnt know!
