we used SVG last month and were pleased with the service - we flew to St Vincent and returned from Canouan. Below are baggage regs for SVG (no problem for us we like to travel light as we were sailing)
Luggage allowances on Shared Charters:
FREE CHECKED BAGGAGE ALLOWANCE IS ONE (1) BAG, 20 KGS (44 LBS) PER PASSENGER (INFANTS INCLUDED).
A BAG THAT EXCEEDS 20 KGS (44LBS), UP TO A MAXIMUM OF 32 KGS (70 LBS) WILL BE CHARGED AT A RATE OF US $1.00 PER LB.
THE CHARGE FOR A 2ND BAG IS US $50.00 PER PASSENGER.

THE MAXIMUM NUMBER OF CHECKED BAGS ALLOWED WILL BE THREE (3) BAGS.
ONE (1) STANDARD PIECE OF HAND LUGGAGE PER PASSENGER IS ALLOWED - NOT TO EXCEED 6 KGS (13 LBS).
There are weight restrictions on all aircraft. Should luggage be left behind, the airline will assist you by forwarding it on the next available aircraft
"Soft" cases are recommended since the luggage compartments on these aircraft are small.
Due to flights operating into unlit airstrips, passengers are advised to travel with overnight essentials in their hand luggage
