wageslave , your scenarios are hoax.
one example: Lufthansa Italia like 5 yrs ago had Italian copilots. when it went out of business they were given the chance to move to fra/muc into real Lufthansa contract (compared to BA about 30% higher salary, short haul about 15 days off a month, long haul 17). one requirement at that point was german language proficinecy. but not before that with ops in Italy. many took the chance , learned for 6 months , and were integrated in the main seniority list.
