I would like to travel from Montreal, Canada to Japan, but a plane ticket is expensive so I want to minimize travel costs.
I like to explore and visit new places so alternative routes through unconventional means, multi-modal transport or through other countries are definitively fine. If possible I would like to avoid crossing the ocean by boat as it is likely to be prohibitively long, but otherwise boats are fine.
Is there a way to travel from Canada to Japan that's cheaper than the most direct flight routes?
My guess is: hitchhike from Montreal to the west coast and take a plane to Japan from there?
Note: I don't think it's a duplicate as I don't want to restrict answers to air travel only, all forms of transport should be considered if they can reduce the overall cost. Travelling to a neighboring country and taking a bus/ferry/train/etc. is a perfect example.
