J* have sourced 3xA321s ex American Airlines which needs major mods b4 going into service. That's how desperate they are !
Thats the incorrect terminology to speak, doesnt matter if they are desperate or not
Take for an example if you take a BAe 146 out of America and to put it in service in Australia you would have to convert the C - Class bulk hold due to the fact that FAA aviation laws are completely different to that of casa and would need changing. Lead time for conversion would be 2months.
