There are number of ways to save money on travel airfares. However, there is one that you may not be aware of. Basically, airlines have a policy of refunding ticket holders the price of the difference if a fare drops. Yapta which stands for "Your Amazing Personal Travel Assistant," has built its business around this policy as a place to find out if you are due any money back from a fare drop.
Users can enter their flight information and the price they paid for a ticket and the Seattle-based startup will track the ticket price for you. If the price you paid for your flight drops before your trip, it will let you know the price difference and how to claim a refund or vouchers from the airline.
You might want to give Yapta a try - it could save you some money the next time you travel by air.
