Is most of the air traffic direction North/South?

Most direction flying out is north, but to fly on you're going south

Currently all our nonstop destinations are north of Southwest Florida International Airport (RSW). Our nonstop route map can be found on our website at https://flylcpa.com/routes.php. If you are looking for more specific information regarding aircraft flight patterns, some of that information can be found on our Aircraft Overflight Program webpages at https://flylcpa.com/noise/. However, the FAA, not the airport, regulates and controls the airspace in the United States.

Well, Florida is south of most states!
