Hi guys,
Just to make a slight correction...
At this point in time, when you finish your Cessna / Baron / Learjet, you'll be put onto the B777 fleet, EXCEPT if you signed up for Cargo, and in that case, you'll be on the B744 fleet.
Currently, there is no plan to have a Second Officership for the A345. So, if you're passenger fleet, it'll be the B777, Cargo, B744.
Cheers!
