7. Use "hidden-city" ticketing
Another gamble that can also save you a lot of money involves hidden-city ticketing. Instead of booking a costly non-stop flight from Hartford to Charlotte, book a cheaper flight from Hartford to Atlanta, with a layover in Charlotte, and then simply stroll off the plane in North Carolina.
While there are websites to help you uncover these layovers (skiplagged.com and flyshortcut.com are but two), the airlines are wise to the scam and have started to crack down -- both on the sites and on passengers. Get busted and you could be fined. So make sure you know your airline's policies, buy a one-way ticket so they don't cancel your return trip (and they will), and don’t check any bags.
8. Fly two different airlines
Once upon a time, two one-way tickets costed A LOT more than a single round-trip fare. Not so any more. These days, buying a one-way fare can be more cost effective. Plus, you can often score better departure times and/or arrive and depart from different airports. Some online booking engines already mix and match flights, but they just don't show you all the available combinations. So be sure to check each airlines website.
