Keep your dates flexible. Many airlines have specific requirements for a minimum and maximum total number of days to be spent in a location in order to get the best deal. For the cheapest flights, stay for a minimum of 2 nights and a maximum of 30. Try to stay at your destination over a weekend, as flights that bookend a Saturday night are cheaper than those that lack a Saturday stay.
Visit individual airlines’ websites. Although airfare search engines are great, what they don’t tell you is that some airlines reserve their best deals for people who visit their sites specifically. Search for a list of large and local carriers in your area, and then search each of their sites specifically for the best deals. When coupons, discounts, or sales are offered, they will typically only be advertised on each specific carrier’s site and will run for only 1-3 days.
