There are a lot of websites wherein you can begin searching for cheap flights, or cheap travel packages. There's Travelocity, Orbitz, Kayak, Priceline, Expedia, etc. However, searching through these sites one by one can be time consuming and most often than not, you'll only end up searching through two to three sites to compare the deals on cheap airline tickets so you might be missing out on lower rates offered by competing websites.

Thankfully there are now price comparison websites that would allow you to only search using one website but get results from a variety of different websites offering cheap airline tickets. Airline tickets comparison websites that come to mind include: Farecompare.com, lowfares.com, and cheapflights.com.

Most of these price comparison websites have common websites that they search through such as Travelocity and Orbitz but the key is instead of going through individual travel websites, you can just use these price comparison websites since even though you only go through two to three of these price comparison websites, chances are, they'll be able to search more thoroughly than you, guaranteeing you the best deals on the Internet.
