Search for Alternate Arrival and Departure Airports
In metropolitan areas with more than one airport, such as New York City, Washington, D.C., Los Angeles, London, and Paris, having multiple options often means lower, more competitive ticket prices. Whenever possible, check other area airports to see which departure point is cheapest. Just make sure in advance that you can get to and from the airport: You may save $100 by flying into Stansted instead of Heathrow, but you will also be 40 miles away—an hour-and-a-half drive on a good traffic day. Always take into account cab or car-rental fees if you choose an alternate airport, and know that you may have to leave extra early to make your flight.
