In general, airfare is cheapest midweek and at odd hours (early in the morning, late at night, red eye flights). When you search for fares, indicate that your dates are flexible, and most websites will show comparison rates for different days.

Midweek is usually the cheapest (Tuesday, Wednesday or Thursday). Also, avoid school holidays and book as far ahead as possible (at least 3 months) in order to get the best deals.
Weekdays are generally the cheapest days of the week for air flights. Tuesday and Wednesday travel times are typically least expensive, while weekends are most expensive. Buying tickets in advance is also the best way to get the cheapest fares. As a general rule it is cheaper to fly on weekdays than it is to fly in or out on weekends. Mainly because people tend to fly more on the weekends so they offer cheaper tickets during the week.
