Altiplano is right...(Rouge 77.5 pay garantee, overtime and profit sharing) but do not get paid 13 month/yr like some European,
plus if you are lucky to get Ca position in the first 4 years you get better pay, min garantee on EMJ Ca year 2 is $10,372/mo. or 120K/yr.
Also all years of service at mainline count for Ca pay (ie you spend first 2 years Fo the year 3 you upgrade to Ca you get Ca yr 3 pay) Rouge is a bit different.
About spending you life & career working at AC...very few leave before retiring,
In hard time some will take LOA to fly elsewhere but the vast majority will come back to AC.
