Neo, is this you? :D The blog post is a bit hard to go thru. I'll just grab the 3 cheapest ones. Btw, how am I supposed to use those codes? What Matrix? (no trolling intended, I honestly want to know).
Most of the flight hackers use Matrix because you can run more powerful searches. If you click "Advanced Routing Code" then type in one of those lines, then add origins and destinations served by that airline, you'll get a list of prices.
If people want, I can also post a full list of the origins and destinations per airline here.
