Airlift into the BVI is very low and I don't see that changing unless Delta brings in flights using the new planes which are years off from being delivered in quantity.
There is good news. Delta is up-gauging service on the current non-stop ATL to STT to ATL route starting April 3. Daily service up-gauged from 737-700 (108 seats) to 757-200 (199 seats). Plus an additional flight on Saturdays ATL-STT-ATL beginning May 5th with an additional 757 (199 seats).
Plus, Delta is resuming JFK to STT flights with a 757 (199 seats) starting Saturdays on April 7th. And 7-day daily service JFK to STT with a 757 (199 seats) starting May 24.
Our islands are coming back people!
