Sorry, Cody, I don't have the answers for your questions, but I have to agree with you: that region would be EXTREMELY profitable for airlines from North America.
Some days ago, I was watching TV and by chance I watched a documentary about Dubaï. I became impressed! They have buildings, shoppings, companies,... that we here in Brazil don't have at all! The quality of life and aquisition level (power to buy things) are told to be equivalent to those found on top countries such Sweden and Canada!
On the aviation field, just take a look at Emirates! See their services quality, see their finances! It's amazing! Very few airlines in the world may be compared with it!
Maybe in some years American and Canadian airlines will be looking at that city/ region. By now, all we know is that Emirates will be using the new A340-500s on non-stop (top-!) services to the USA. Maybe after them, others will follow this way... I hope!
