Here are some top tips for gaining the cheapest flights possible:

• Buy late online - search for your flights as close to your departure as possible.
  
• Look for your flights late at night - most airlines post their flights around midnight.
  
• Buy package deals - these always give you cheaper flights, as long as you are prepared to book your accommodation as well. Although, if it is really close to your departure date, these packages can be cheaper than buying a plane ticket! So snap one up - you don't have to use the accommodation!
  
• Search around the different airlines on the internet - calling an airline with a quote you already have may lower the price.
  
• Look at budget airlines - especially if you are only going short-haul, they can be very affordable.
  
• If there is food provided, and you would prefer to cut the expense, you can normally opt out after booking your ticket, but make sure you ask the airline this in advance.
