For Air Sunshine, just be aware that they will combine flights to get a full plane. Their afternoon flights to VG are 2:30 and 5:30. So, if you booked the 2:30, you may be combined with the 5:30 flight and leave anytime between 2:30 and 5:30. But if you booked the 5:30, you may leave earlier than 5:30. Every day is different depending on their bookings. Good Luck!
