What Determines the Kind of Aircraft That Will Be Used for a Particular Route?

Generally, our wide–bodied aircraft fly overseas because they have a greater fuel capacity for longer routes, but you may also see these on short reposition flights, such as Toronto–Montreal. Seasonal demands also dictate aircraft type. I fly to Barbados in the Airbus A320, but the Boeing 767 is used during peak winter months to accommodate greater passenger volume. The ultra–long–haul polar Hong Kong flights are only flown with the Boeing 777, which carries enough fuel to send a Honda Civic around the equator about 84 times.
