I don't have an issue with the US Government asking to see passenger lists for those flights that cross over US Territory, if they force US Air Carriers to do the same when they fly of Canadian Territory. An EVERY US AIR CARRIER flies over Canada when going to Europe, Alaska and is some instances Asia. When ever possible airlines will fly on a "great circle", you go to Europe following a polar route because you are over land in case of an emergency. Same when going to Asia, you try to stay close to land so if you have to ditch you do it close to Naval Search and Rescue. How would the US Government and the MEDIA react to Canada telling a flight to turn around we don't like someone on one of your flights. Refuse and be forced to land.
As for Canada letting market forces govern how airlines work, it will never happen, Canada does not have the population density to enable this model to work effectively. Canada was formed in the sprit of cooperation and shared responsibility. Unlike the US where “Individualism” still rains supreme. Case in point, our Health Care system tries to look after everyone by sharing the burden. How many times has such a system been suggested for the US only for it to be defeated because of the overwhelming believes that “that’s his problem, I got my own”. American’s as individuals are generous to a fault, add politicians to the mix and its “tough luck Charlie”.
And just one more time, the terrorist who flew the jets on 9/11 were all in the United States on approved VISAS. Nobody came from Canada. Will they use this method in the future, who knows? But if I were a betting man, I’d be looking at container traffic.
Oh, by the way, remember that we have a little more than a year to go before anyone visiting the US will require a Passport, including American’s returning from those day trips and vacations that they used to take to both Canada and Mexico. That traffic is going to dry up. Soon the only Canadians visiting the Excited States of America, will be on those flights that over fly US territory between 2 Canadian cities.
