To get to St Barth, you must first fly into Princess Juliana International Airport in St Maarten (unless you're taking a private charter from San Juan).

- WinAir is the most popular airline flying between St Maarten and St Barth. The St Maarten Daily Herald recently announced that WinAir has added a 19-seat Twin Otter to its fleet, increasing its number of airplanes to six. They also stated that another plane would be added to the fleet during the first week of December to further their attempts to accommodate all passengers during high season.

- New passport scanners were recently installed at Princess Juliana airport and have been causing delays and long lines. Airport officials have considered re-introducing manual checking of passports until the problem with the automated system can be corrected. If you are already checked in and your baggage is loaded on the plane, the plane will wait for all passengers to board before taking off. However, plan for extra time if you only have carry-on luggage or you could miss your flight. The delay with the automated scanning is thought to be due to the fact that the data scanned from the passports is sent to Curacao where it is checked against an Interpol database. Justice Minister David Dick's intention is to link the passport-scanning system directly to the Interpol database to shorten the delay.
