Clayton J. Lloyd airport has 5,000 feet of level runway available, allowing a large variety of aircraft to land and take off. Compare that to St. Barts with only 2300 feet of DOWNHILL runway that ends in the water...
5,000 ft is a decent civil airport runway for anything other than the big long-haul airline jets.
SXM's PJIA runway, by the way, is 7,546 ft long...
