If you'd like to have some extra spending money on your trip to Lviv, listen up! As every seasoned jet-setter knows, avoid booking at the last minute. Airfares are generally more expensive close to the departure date. Also, do some online research and compare your options. If your destination has several airports, you may be able to nab a terrific price by flying into a less busy terminal. And finally, remember that the early bird catches the worm. Know what a typical airfare costs and have your credit card ready to snap up a ticket as soon as you see a great bargain. The sweetest deals don't last long.
