Combine two separate fares rather than buying one fare. Let’s say you’re flying from New York to Eleuthera in the Bahamas. Check on one of the big sites like Expedia or Orbitz for a single fare (for example, JFK to Governor’s Harbor, Bahamas) and then do two separate searches (JFK to Nassau and Nassau to Governor’s Harbor). Since JetBlue flies JFK/Nassau you’ll want to check JetBlue.com separately). Chances are the two-fare strategy will save you a lot of cash. This fare trick also works for flights to Europe (fly into London or Manchester, UK on one fare and then hop on a discount European airline to reach your final destination) and Asia. To search route possibilities on these discounters, check out the Airfarewatchdog route maps page.
airlines deals:Buy tickets on an airline that will refund the difference if a fare goes down. Let’s say you’ve done your best to find the lowest fare, and then the day after purchase your non-refundable fare goes down $100. Sure, if you ask for it you can get a refund for the difference, providing of course that you don't change the times or dates of your flights (and the only thing that changed was the price); but it’s a little-known fact that some airlines will charge you a “service” or “administrative” fee as high as $100 for domestic fares or from $200-$300 on international ones, wiping out any savings. United, however, will give you the entire fare difference without extracting a fee, as will JetBlue as long as you accept the reimbursement in the form of a voucher good for future travel. Northwest charges just $25, for both domestic and international fares. American and Delta extract the $100-$300 fees; Southwest gives you cash back without charging a fee. Even on these less generous airlines, however, we’ve heard of plenty of instances where a polite entreaty will get you a full fare difference refund without the penalties, so it’s worth a try.
