If you'd like to have some extra spending money on your trip to Montemorelos, listen up! As every seasoned jet-setter will tell you, don't leave booking until the last minute. Prices are generally more expensive close to the departure date. Another easy way to nab the most competitive fare is to research all options. If your destination has more than one airport, research the cost of flying into a smaller terminal. Lastly, be prepared to secure your seat quickly if you find a real bargain. It might not be available for too long. With a bit of know-how and a little good fortune, the perfect airfare can be yours.
