It seems to me that there are airports in the U.S. that happen to be close to the Canadian border and can offer less congestion and whatnot. It wouldn't be a whole lot different if New York City were located on the other side of the border. You could probably make a case for Americans to come to Hamilton and fly if you offered the same kind of thing as Buffalo. I understand the cost factor, but I do think a lot of that is getting away from the time it takes to get processed.
