Been playing with travel sites all day, (Kayak FTW!) and I discovered several interesting anomalies with which I plan to tour the world for some $2k in air travel. Flight arbitrage, if you will.

You see:

• Travel within Europe is really, really cheap. As in €30 £5 London – Madrid round trip. So Europe can be thought of as one point: London, by far the cheapest hub.
• Round trips are a considerably better deal than one-ways. I understand they are the industry’s version of wholesaling but a 40% difference seems too much (a one-way can be 140% the price of either round trip leg)%.
• Travel order is everything. Mexico-Tokyo, one way is some $900. Tokyo-Mexico, one-way too, no less than $2,000! That’s right, the exact same distance can cost you over twice as much depending on where you start!

Putting it all together, my plan is to buy the following round trips: Guadalajara-Toronto, Toronto-London, London-Tokyo. I travel from Guadalajara to Toronto, then to London, then to Tokyo, where I stay 3 months. Then I return to London, where I stay some 6 months (to travel cheaply around Europe), then I return to Toronto and stay some 3 months, and only then do I return to Guadalajara.

All this for some $2k!

It’s a tad complicated and wasteful, and I need to plan far ahead, but the price’s pretty good, right?

Can you think of something else?
Know any other anomalies? Youth discounts? Passes?
Got any tips?

I haven’t bought yet but I think I will soon!
