Yet here we are talking about routes like CYYZ-KIAH which is a regional route served by E175s and CRJ700s (and not even always full).
Why put an expensive mainline operated CSeries with even more capacity on this same route?
Or lets talk about that Toronto - London City route using the CS300. Today Air Canada flies a profitable route YYZ to LHR on a 2-class 200 passenger 767-300 and benefit from Star Alliance connections at the LHR.
Why compete against the current service using a smaller plane to LCY and incur all the cost of operating a new type? Even in the best case scenario, the CSeries would simply cannibalize Air Canada's existing service!
Show us the numbers that these routes make sense from a financial perspective!
It's easy to say "don't build regional jets" but why is Air Canada planning to use the CSeries exactly as regional jets, on existing E190 routes?
Why pay premium for the CSeries long range capability then simply fly them on short regional routes?
Why is it that Embraer has record backlogs and shares (in R$) trading near all time highs?
