Flight took off 40 minutes earlier than scheduled. I missed the flight and was stranded on Sint Maarten overnight. They offered a stand-by ticket on the 4:40 flight to Saba the next day. I asked a staff member for the sales office phone number so i could purchase a guaranteed reservation for the next day instead of being in limbo. It took over 2 hours of hounding these folks for a ph # and still no cooperation; customer service is nil!
