When flying into a particular city, broaden your search for local airports. Although the larger, international airports usually offer the best prices, this isn't set in stone. You can sometimes save hundreds of dollars simply by flying into an alternate airport. Even if it's a little farther away, the money saved can make it worth it.
"Always look at all the alternate airports (even small ones). As an example, Allentown will sometimes have lower prices than Philadelphia International Airport. Pay particular attention to those alternate airports that are dominated by Southwest," offers Clem Bason, CEO of value hotel search site goSeek.
Another hack? Check to see if two one-way tickets are cheaper than the round trip fare. You might be better off flying into one airport, then going home out of another.
