We just found a really useful airfare website that breaks down costs based on the week and months of the year. It’s called Fare Compare.

FareCompare does not sell tickets. But after you find the flight you want, you can book your ticket directly with an airline or travel agency. This information is provided free of charge for non-commercial purposes.

Sample fares for April 2007: 

New York (JFK) to Accra on American Airlines: $1094 USD

Los Angeles to Ho Chi Minh on Malaysian Airlines: $680 USD

Los Angeles to Quito (Ecuador) on Continental Airlines: $522 USD
