Sign up for price alerts on travel booking websites as soon as you find out you need to travel. Make a list of the airfares available to you, and sign up for email alerts that alert you to drops in price that you may not find any other way (see Resources).
Call several travel agents and inquire about their services for your trip. Travel agents often have connections that you don't have access to. You may find an agent that offers you a good deal in exchange for an opportunity to win you as a lifelong customer.
Travel with a companion. Occasionally, your search for last-minute accommodations may lead you to a cheap package that includes airfare and a hotel stay. Many times, these deals require two people to take advantage of them.
Search for airfares that are in the middle of the week. When fewer people are traveling, more seats are available. Airlines would much rather have someone paying something for the seats that would otherwise be empty.
Compare the rates of nearby airports. Also consider hotels that are located in a smaller town near your destination.
Call the airlines directly. If all else fails, talking to a customer service representative from the airlines may prove more fruitful than searching the company's website for low last-minute fares. When you call, ask about round-trip rates. Even if you are only going one way, you might be surprised to find a cheaper rate on a round-trip ticket.
