Here’s my theory.
Moochell has goten used to jetting around in AF2, vacations, etc. Her and Barry know in ‘16 they won’t have a large private jet to continue the lifestyle.
Just like a ride in Chicago, they boost a 777-300, hide out in a chop shop, change the data plates and voila, they have their own private jet, the size they require, that shows up from an anonymous donor.
The passengers? Probably ransomed to China, with some state secrets, in exchange for fuel and maintenance.
