Route Guide
The Florida Gateway
Miami is the natural gateway between the US mainland and the Caribbean — and for St. Croix, the American Airlines seasonal nonstop from MIA is the golden ticket. No connection through San Juan, no inter-island hop, no weight limits. Just a 2.5-hour direct shot from Miami International to Henry E. Rohlsen Airport. The catch: it only runs during peak season (December through April), when St. Croix is at its most vibrant. Year-round, MIA remains a critical hub for STX travelers — American connects to San Juan multiple times daily, where Cape Air and Silver Airways continue the journey to St. Croix.
💡 Booking Tips
Tips for This Route
📅
Book 3–4 Months Ahead
American's seasonal STX nonstop sells out fast. For Christmas and New Year travel, book as soon as the schedule opens — typically 11 months out. Fares spike dramatically in the final 3 weeks.
🔗
Year-Round Fallback
When the nonstop isn't operating, connect MIA → SJU → STX on American + Cape Air. The connection adds ~2 hours but runs year-round. Build 90 minutes at SJU minimum.
💺
Choose Your Seat Early
American's narrow-body aircraft have limited Main Cabin Extra seats. Book your seat assignment at time of purchase — good exit row seats disappear fast.
🌅
Morning Departures are Best
Early MIA departures give you a full afternoon arrival in STX. Afternoon flights can get delayed by Miami afternoon thunderstorms in summer months.
