The current overall plan as far as I've been told by the little birds....
AC Mainline - B777 & B787 - Long Haul Flying Only
AC Rouge - B767 & A320 (possible switch to B737) - Heavy Domestic & transborder routes, sun destinations, Europe. This is a low wage/cost carrier. Same unions, but with many reduced rates.
AC Express BannerSky Regional - EMJ 170/190 & Q400 - Domestic & Transborder - No unions, very low wages, low ticket prices.
Jazz - CRJ & Dash 8s - Short haul Domestic & Transborder - Unionized, high wages, low ticket prices, old airplanes, cpa....uncertain future
Georgian - CMA - Tier 3s - Beech 1900s - Very short domestic & transborder - low wages, low costs, will be around a long time.
