Expanding one's knowledge is always good!
But Cubana and Boeings?
Not in my lifetime.

Not sure about the An-148, but everything else is available.)
There are not many FSX native Russian equipment out there, so the Boeing and airbus help fill in the void.
Err, there are no native freeware AI models at all...
Considering that Cubana flies to Canada, getting Bombardier products into the fleet (if only on a leasing base) might not be THAT unrealistic. Same for Embraer jets.
Maybe I can find a painter for your Do328 lol.
