There are a lot of such sites on the internet, and I've tried a few others, and the best for me is europe fly. Buying tickets on the internet can save you up to 30 percent, and that site allows you to save even more money. There I can find tickets to any destination for a reasonable price. For example, last month I visited five countries in Europe, and spend on tickets less than 70 Euros. And there is no secret scheme, only a proven service and buying tickets in advance.
