Winair has been around since 1961. We’ve flown them in/out of SXM as well as other Caribbean airports on numerous times since the early 1990’s and can tell you that they are pretty much like any of the other Caribbean commuter airlines, they have their good days and they have their bad days. The thing is you never know what type of “day” they will be having the day you fly. Like most Caribbean commuter airlines they have a relatively small fleet of planes so if mechanical issues or weather delays disrupt a particular flight or flights it can have a ripple effect through their entire system. Hen island hopping by plane around the Caribbean it helps to be patient and flexible.
