Well...if it’s Last in, First out, they will need to borrow Pilots from Virgin to keep the operation running, as the 737 is largely crewed by the back half of the list.
I assume they will expedite this whole process now essentially with the Airbus ending service sooner rather than later, well rather than sitting around idle for the next few months.
The downtime can be used type training Airbus Pilots so come August they are all set to go.
Are there any VARA opps for these 737 or Airbus guys?
