555,
Well I guess I missed the point of your post to which I initially replied:
If you have plane loads of emirati's... By all means come as much as you want. 10 flights a day.
To me that indicated the position taken by many, that EK/EY and/or Qatar should only be allowed point to point traffic. Was that an incorrect understanding of your statement?
My point is that AC/LH and many other major carriers operate hubs and funnel pax from multiple points through these hubs to many downline destinations. In fact AC is proud to state how much business they are getting from US pax flying though YYZ to international destinations. My question to you is, why should it be considered an unreasonable business practice for some select carriers to do the same?
