I think you will find the IASC approve they just received will not allow them to wet lease and it will need to be VA's metal operating the services.
In the short term (1-2 years) I think they will pull 2 aircraft of the transcon flying (there has been a softening in the domestic traffic) and replace them with B737's. These 2 aircraft would then operate the international services.
The international flights will require additional crew to operate them, as most likely they will be operated as a 3 man crew. This along with the B737 flying increasing should be enough to absorb all the Ejet crew, it however may require some pilots to move base if they want to retain their current rank or a change in seat ie back to the RH seat for captains or back to the second row for FOs, should they want to remain in their base.
