Would that make the airport code DOG?
That could work, but someone would have to check if it is available. It is a good BET that the drama behind this Airport Wars will continue. Some lawyers, lobbyists and handlers are stretched thin right now.
(FYI for new to SoWal or the area, Ebro is the well known dog racing track in the area. Ebro, along with the new airport, were once within the original borders of Walton County. They could have just called it the Walton County International Airport. That would name it after a historical famous place and person. Or, it could be named the SoWal International Airport to get that southern beachy feel into the marketing mix. )
