I posted this in the issue tracker also but really need some help as its costing me quite a bit and pushing my profit matgin down!
I leased 5 used A340-300s on Game world S4B but I can't assign them to any routes.
Each of these aircraft are making a monthly loss of $2m and to return to lender would cost in excess of $350m and I cannot afford that.
I had ordered 5 New of the same aircraft and these are able to be assigned to routes without issues. (I've attached a screenshot of the Flight assignment page with A340-300s selected)
Any help or advice would be apprieciated!
