Next time you are about to jet off on your next trip away, consider whether you will be crossing state lines from your city of residence to the airport you must depart from. Many of the nation's busiest airports are located nearby or within the city limits, but there is a handful across America that serve major population centers of a different state. While this list is not exhaustive by any means, Simple Flying put the spotlight on a handful we found.

Can you name any more? Crossing the border to save money While it doesn't always spring to mind when purchasing your ticket, the cost of your airfare comprises several fees, levies, and the actual airfare for the airline itself. Passengers are charged to fly to and from a destination, bound by rules and restrictions for that airline. Airfare taxes also include several US government-imposed taxes , including federal ticket excise tax, passenger facility charge, federal security charge, federal flight segment tax, and passenger facility charge, which are all passed onto the consumer.

The airport you are departing and arriving from also charges a landing and parking fee for the aircraft to visit; in return, this cost is also born by the traveler, which is why some airports are cheaper to fly to than others (a prime example being Baltimore/Washington International Thurgood Marshall Airport (BWI), versus the more busy Dulles International Airport (IAD)).
