Depends whether you want to live in Paris or Dublin... But I wouldn't recommend !!!!tyJet anyway, management is called the in-house "gestapo"... Aircraft are old, noisy and dirty and people rarely stay longer than one year...
But if you like that AF uniform, and want to join WX then yes, you better get your french books out again. Can't really justify serving AF pax if you don't speak a word of french can you ???
