AC183, yes, your right about the cruise ships. One of the main two reasons AC started Miami-Vancouver is because of the huge amount of South Floridians who visit Alaska, though I would think there would still be the traffic coming from Canada in the winter, after all, it's only an A319 (112 seats, I think). Your explanation makes sense, though. I really think it's sort of odd that AC decided to do YOW to FLL instead of MIA, though. AC has a much greater presence at MIA (as many as eight flights a day during the winter), and, even though most of the passengers are undoubtley going to be O&D, MIA at least offers connections on United, Varig, and Mexicana to those who want it. FLL is cheaper to land at, however, and most people in Canada would probably perfer to connect through YYZ.
