Got in contact with VI Airlink. Currently, they will only fly for 5 passengers. We will be flying EIS - SJU - ATL. Booking Delta/Seabourne code share ticket with no checked luggage. Will be looking into the private boat operator idea. It sounds great except for the fact that seasickness is the reason our BVI trips are land-based only. Two weeks on Anegada will be worth a little suffering.
