Hi Airbus,
I saw that also but I believe the main target audience was the Air Finance conference? I know Bombardier have been extolling the virtues of the C-Series to the leasing community especially considering Bombardier's market forecast predicts that up to 50% of the eventual fleet will be owned by lessors. It's potentially an correct forecast as 40% of the current orders are from a lessor (LCI) but as usual time will tell.
Either way I think WX would be creating a stiff challenge for themselves by going for the C-Series, my own experience of EIS of a new type wouldn't fill me with hope that the C-Series will have a smooth EIS.
