The key to airfare savings is knowing when to book. Yes, believe it or not, there is an optimal day of the week to book flights. What is this magic day and time? Tuesday afternoon. The reason is that many airlines launch their sales late on Monday. Then, competing airlines respond by lowering their prices, leaving you with a great deal.

Hotel savings work a bit differently. While it's common practice to book far in advance for the best bargain, the early bird does not catch the worm in this case. According to Travelocity, the longer you wait to book, the cheaper your hotel rates will be. In fact, you can find the best rates one week before your travel dates. It seems counterintuitive, but it's true.
