I assume coming from West Coast area is always expensive. You seem to have gotten a good price. Kudos to you.
I got a surprise when I booked for March 2026 direct BOS- SXM Sat March 7th in cabin, $246 each person (total $492.) Now just booked return $311 per person
I figured something was wrong with those prices so I jumped fast. Never have gone to SXM ever before that cheap. Something's happening with the airlines.
