airline tickets The most important tip for finding the lowest airfare is to purchase airline tickets in advance. In one specific example, airline tickets purchased with no advance reservation cost $515 dollars. Purchasing the tickets 7 days in advance dropped the price to $195. With a 14 day advance purchase, the tickets dropped to $120 dollars. So, a 14 day or more advance purchase of these airline tickets would save $395 dollars. Often you can find 21 day advance purchases which will save even more. So it would usually be a good idea to plan your travel in advance if possible. airline tickets
