I am aware that many ex_AN drivers have applications in at J* . Many have much A320/330/340 time. None would have less than 10,000 hrs total time. I dont think that any will leave good jobs to go to this gig, there would have to be a substancial carrot involved.
A lot of guys here in VN just forked out big $$$$$ for B777 type ratings and are'nt keen to do it again so soon. I guess if J* want people with experience and proven ability, they will have to reconsider their stance on pay-for-rating.
