Perhaps we should test it.... don't know if it's by cookies or ip address, but it's how the site knows it's you. As I said, I don't want to go all tinfoil-hat, but it fits right in with the information in the article, and I have recently been discussing 'targeted' internet advertisments with some friends on another board. It fits.
I'll let you know, or you let me know next time you're hunting a flight, and we'll give it a try testing the theory.
