I saw this article about VG's airport reopening a few days ago (https://www.bvibeacon.com/taddy-bay-airport-in-virgin-gorda-reopens/), and reverted to a prior thread here started by RatmansWife that touched on the cost of flights from San Juan to VIJ (http://www.traveltalkonline.com/ubbthreads.php/topics/263867/reservations-on-southwest.html).

Following up, it appears that Air Sunshine now has scheduled one flight per day from SJU to VIJ at 2:30 p.m. ($275 one way), but I also called Cape Air, and was told by the agent that it's commencing service on that route starting on December the 17th. A subsequent search of its website indeed shows three flights per day from then forward: 8:43 a.m. ($348); 12:43 p.m. ($348), and 4:16 p.m. ($498). https://book.capeair.com/plnext/CapeAirdx/Override.action#/FPC).

As to the cost, Cape Air is selling its 10 segment TravelPass™ for $2,390, which is a great price per flight (good for a year, segments can be used in either direction, and up to five persons on a group account: https://www.capeair.com/travelpass/index.html).
