RE: Boeing to enter regional market…..
I am certainly not surprised that Boeing are taking these steps. Airbus have done nothing but grow and catch-up recently. Boeing may feel slightly threatened.
As for classification of the A318 Kabir, From first sight it looks more of a regional than say the 320/319, though borders on the edge of short-haul. I have not seen the specification yet though.
