It's not a secret, but it is small and has few flights, which are usually expensive. I live in New Orleans. I travel to Biloxi... well... always! My best friend lives in Dallas. Sometimes, we look at flights into Gulfport so we can go to Harrah's on the coast, rather than in New Orleans. Again- few flights and expensive, so she has flown into NOLA every time. I know the Dallas to Gulf Coast thing very well. It's not an unreasonable question. I'm not sure it matters in the scheme of the case, but I was trying to get a time frame/ travel reference for myself. I'm not suggesting that it is impossible or that you need to belong to some secret club to fly into that airport.
