I used to fly charters about 40 years ago - I moved up the ladder and I'm retired now. Back then it was about the same price - per person - for 8 or 9 people to take a charter between the islands than go sched. I suggest you write to SVG Air and ask for a charter rate (and double it for the return flight), then compare it to the scheduled fare for your whole party.
The big advantage of a charter is that you tell them when you want to fly.
LIAT is supposedly running three hours or more late these days - none of my contacts know why - and part of the problem may be industrial action at the Barbados Airport. Those actions do not affect the charter companies, so you need to balance your costs against missing your flight back home while LIAT screws around.
SVG Air also offers sched flights, but those may be affected by the industrial action where the charters may not.
