Air Canada recently started a long haul LCC, Rouge, no shiny Air Canada 330s for them, old 767s!
No doubt the Air Canada team search the globe for the 'best model' and 'best management' in regards to a successfully run LCC.
No doubt they wanted to find the best approach in regards to LCC v parent company and competing on same routes.
New aircraft for the LCC v older aircraft made available from parent, whilst parent get new aircraft and retain their long term, loyal customer base.
I guess the Canadians didn't look at the QF/JQ model
