Many travelers likely remember their first flight out of John Wayne Airport (SNA) in Southern California. Situated in Orange County, the airport primarily serves cities southeast of the greater Los Angeles region and can be a satisfactory alternative to the always-busy Los Angeles International Airport (LAX). Although SNA may be a much easier airport to fly into and out of, some pilots may say otherwise. Unlike other airports, which are surrounded by more space and have longer runways, SNA has a unique layout.
