EIS entry fee is $10/person unless you’re a resident, have a BVI passport (even if you live elsewhere), are a judge of the Eastern Caribbean Court, etc. If you leave and come back within the same visit you don’t pay again. Departure tax is $40/person, now included in the ticket (why tickets out cost more than tickets in).

Scheduled air includes the charges (except the environmental), whereas charters probably quote them separately because they are per person.
