It is an Airbus 340-600, the longest commercial aircraft flying today, longer than the A380. It could accomodate up to 475 passangers. It is a different and bigger version than the A340-200 that normally Air France lands in Sxm(it could be a problem for a fully loaded A340-600 used for commercial use only to take off from Juliana). Engines are bigger too. It is a massive plane.
Most likely passangers of that plane will end their trip in St. Barth.
