I know there are hundreds of websites dedicated to helping customers find cheap flights, but I thought I would share my favorite.
ITA Software is used by many websites including Kayak and Orbitz to discover the cheapest tickets. Instead of using one of their client's sites, like Orbitz, I prefer to get the best deals by going straight to the source. On ITA's site, you can click on Airfare Search, which leads you to the cheapest flights around. If your schedule is flexible, which ours is, you can choose to search for an entire month. We used this website to find insanely cheap tickets to Europe. Happy travels.
