Albinati
Dasnair
Tag
Globaljet
Jet Aviation
Privatair
Comlux
all this VIP/Corporate airlines are recruiting at the moment, and they are all based in Geneva, but with the possibility to work either 2weeks on/2 of, or similar
I know for sure that only Albinati requires females so if u r a boy just give up, and try something like Tag or Privatair or Comlux which are apparently desperate for male flight attendant
Check their website
Good luck to everyone
