Flight
If you are an out-of-town guest the airport within the closest proximity to Ocean Springs is definitely Gulfport which is about 30 minutes away. However Louis Armstrong New Orleans International Airport is also an option with arrival time to Ocean Springs, MS approximately an hour and a half (traffic depending).
Travel Note
While some of our guests are flying in from out of town, and will no doubt have rental cars, we suggest taking a car service of your choosing to and from the wedding to limit the unnecessary parking stresses.
