The Greater Lafourche Port Commission acquired the South Lafourche Leonard J. Miller, Jr. Airport in 2001 and began a series of improvements that continues today. Initial airport improvements included installation of security measures, addition of fueling capabilities, resurfacing of Airport Road, construction of an aircraft storage hangar, and installation of an Automated Weather Observation System (AWOS).

Shortly after the airfield acquisition, the federal and state governments funded an Airport Master Plan to provide a clear view of the South Lafourche Airport's future and its potential contributions to the region. The Port Commission has exceeded that plan's recommendations with projects like extending the runway from 3,800 to 6,500 feet, widening it from 75 to 100 feet, and resurfacing it, strengthening the runway and aircraft parking apron to support wheel loads up to 75,000 pounds, installing airfield lighting, signage, and navigational aids (NAVAIDS), and constructing a full parallel taxiway.

In addition, a Localizer antenna, Distance Measuring Equipment(DME), and Precision Approach Path Indicators (PAPI) have been installed as part of completing a full Instrument Landing System. In the works are additional navigational aid projects, including a Glide Slope and an Omni-Directional Approach Lighting System (ODALS), and construction & development projects to build new airport roadways, expand the airport ramp and terminal, and update the Airport Master Plan.

As a result of these aggressive improvements, the airport is showing aggressive growth. Within the last inspection year (March 2012-March 2013), total aircraft operations at the South Lafourche Airport were the highest in airport history, exceeding 20,000.

Companies in the area need adequate air services in close proximity to Fourchon to transport specialized equipment in just-in-time fashion. With constantly enhanced airfield capabilities and navigational aid upgrades, the South Lafourche Airport can be a valuable resource for the business sector and also aid the public sector in times of natural disasters or national crisis.

The South Lafourche Leonard Miller, Jr. Airport continues to support existing Fourchon and Galliano clients, and with ongoing improvements is attracting new business as well.
