Don't leave locking in your flight to Ham Tan until the very last minute. That's one move well-versed jet-setters use to get the best prices. Booking in advance means more options and cheaper flights. Also, shop around and compare your options. If your destination has several airports, you may be able to score an excellent price by flying into one a little farther out. Last but not least, another simple way to save a few dollars is be ready to book at a moment's notice. If you come across a good deal, don't think twice — snap it up while you've got the chance.
