Follow Cheapflights-ology for the path to the lowest fares:
Shop around for the best deal. One company will never ever always have the cheapest price.
Cheapflights.co.uk offers an independent guide to the best deals from hundreds of flights companies including airlines, consolidators and travel agents.
Compare flight deals to your destination.
Be flexible with your flight times. The more flexible the cheaper the deal. For example try flying on a Tuesday, Wednesday or Thursday.
Try a specialist for international destinations - Canadian Affair for flights to Canada for example.
Generally speaking you will get a cheaper fare by booking early.
Remember that some travel agents will not search all the low-fare airlines.
Be flexible, if possible, with your airports. Flying to or from a nearby or secondary airport can save you big bucks.
Always compare like with like: watch out for taxes, surcharges and fees. Some airlines are more comfortable (offering seat allocation, food and drinks) - so price is not always the only factor.
Be patient when searching to save. Saving is worth it. Think of the money you can spend on luxuries when you get there.
