buying flights early

[gusl]

Knowing that a lot of people will soon be buying tickets from America and Canada to Helsinki on July 3, should I expect to get a better deal if I buy early? Are the airlines aware of conferences like ICML (~500 people)?

Tangentially, Farecast doesn't work outside of America.

The airlines have computer models which regulate how cheap fares are based on how much demand it looks like there is.

For domestic travel, the cheapest fares usually happen some time between 30 and 90 days before travel. I have no idea how this works for international.
