We have been going to STJ for 25 years so I am familiar with STT flights. Certain routes like DC area, Newark and even Boson can be quite reasonable for direct flights. However, outside of those markets it’s hard to fin a “Bargin” no way would I consider flying thru STT for our BVI trips, that airport is a nightmare on a good day. We fly to SJU direct and take Island Birds to VG. Because we can fly cheap to SJU, we can justify the charter cost.
