First of all let’s take a look at the options available if you have internet access, as this is usually the first - and often the only - place people will look when they are looking for cheap flights. If you use a search engine you will find dozens of websites offering flights from a variety of airline carriers at bargain prices. Many of these sites are able to offer discounts because they have bought ticket allocations in bulk to sell on their own sites, and are given large discounts to do so by the airlines. Buying later can, in this instance, work out considerably cheaper as they will slash their prices at the last minute to shift their remaining tickets. However, if you wish to take advantage of this you will have to have a contingency plan in place in case they sell out before you make your ticket purchase.
Other websites trawl through travel and airline’s websites to search for the best deals available. However, these are not always reliable as the larger companies such as Expedia.com have measures in place to stop travel search engines from accessing their site. Consequently, if you are committed to getting the best deal you will have to check the major travel sites in addition to searching for deals on travel search engines, or you could miss out on making even bigger savings.
