There are two airports on the island. The main, truly international airport is Princess Juliana SXM Airport. SXM is the airline code and has been part of my system since the previous millennium, when steam-powered laptops were common.

The other airport is on the French side in Grand Case. It's called L'Esperance, but the runway, and the flights, are rather short. You can fly from Anguilla to L'Esperance making an international flight, but it is a mere five miles. The airline code is SFG.
