How To Save Money When Flying to St. Barts
- Compare routings: Most travelers connect via St. Maarten (SXM) or San Juan (SJU) to Gustaf III (SBH); price both and include the short hop.
- Target shoulder/off-peak: Cheapest fares land in June–Nov and late Apr–May, plus early Dec.
- Avoid peak weeks: Skip Christmas/New Year, Jan–Mar, Carnival, Bucket, and Les Voiles if price is priority.
- Book 3–5 months ahead: Limited-capacity flights to SBH and prime connections sell out early for event weeks.
- Fly mid-week: Tuesday–Wednesday departures typically undercut weekends on both long-haul and regional legs.
- Sign up for airfare alerts: Jetsetter Alerts can send you any flight deals and mistake fares in real time so that you don't miss out on opportunities to book a cheap flight.
