Leaders of airports in Meridian and Hattiesburg-Laurel are working with a consultant who specializes in smaller airport service to make presentations to the larger commercial airlines.
Meridian Airport Authority President Tom Williams said he believes the two airports can make a case for service to one of the larger carriers.
Both airports are trying to replace service provided by Silver Airways.
Silver Airways last week provided the U.S. Department of Transportation with a required 90-day notice of intent to discontinue service between Atlanta and Meridian and four other communities, including Muscle Shoals in Alabama and Greenville, Hattiesburg-Laurel and Tupelo in Mississippi.
Silver Airways replaced Delta Air Lines as the Meridian Regional Airport carrier in 2012 after Delta pulled out of the Meridian, Laurel-Hattiesburg and Tupelo markets.
