If you want to save some cash on your trip to West Yellowstone, then listen up! As any seasoned traveller knows, don't book at the very last minute. Prices are generally more expensive close to the departure date. Another terrific way to grab a bargain is to research all options. If your destination has several airports, be sure to look into the cost of flying into a smaller terminal. And finally, don't forget that it's first in, best dressed. Familiarise yourself with airfare costs and have your credit card ready to secure your ticket as soon as you spot an unbeatable bargain. The sweetest deals never last long.
