I just saw that Norwegian Air is going to resume flights to Guadeloupe and Martinique from BOS, JFK and BWI. We are booked to fly to Guadeloupe at the end of March for a 5 night stay. Our tickets are $188 each, RT.

When we flew to SXM from PHL on New Years Day, we paid $640 each, RT, on AA ( AN EX-USAir route )

I wonder if it might be less expensive to fly to Saint Martin via Guadeloupe. There are numerous flights each day between Guadeloupe and Saint Martin ( Grand Case ). You would have to clear customs in Guadeloupe; but the flight to Grand Case is "domestic".
