Main base 320 pilots get 330 rated after initial period, I think the restriction is once they have 500 hours Airbus at AIH they can MFF. Some other worthies from other bases get cross trained as well. 2 week course back at Toulouse, an ETOPS course and a few line training sectors and you are off. MFF is not a problem, the operation of the aircraft is similar enough, you just have to figure whether you have you beach kit with you or not to remember to flare at 30 or 50 feet
