Can I book all my islands on one ticket?

Rarely. Unless you are using a major carrier's alliance, you will need to book each leg separately. This means you must collect your bags and re-check them at each hub.

Are there ferry alternatives?

Yes, for neighboring islands (like St. Kitts to Nevis or Martinique to St. Lucia), ferries are often more reliable, cheaper, and faster than flying. Always check ferry schedules before booking a flight.

Booking Inter-Island Flights in the Caribbean

Use a regional hub aggregator like Skyscanner or Google Flights to see flight options, then book directly through the regional carriers like LIAT20, InterCaribbean, or Caribbean Airlines. Avoid long layovers by checking the flight frequency on the airline's own booking portal before finalizing your main international ticket.

Map out your regional hubs. Identify your 'main' island hubs. Most inter-island traffic flows through Barbados (BGI), Antigua (ANU), Trinidad (POS), or St. Maarten (SXM). Do not assume you can fly direct between smaller islands; you will almost always route through these major hubs.
Check regional carrier websites. Major international carriers (Delta, United) often don't list small regional flights. Go directly to InterCaribbean Airways, Caribbean Airlines, Silver Airways, or Winair to find the routes that the big aggregators often miss.
Factor in 'island hopper' layovers. Many routes are not point-to-point but 'island hoppers' where the plane stops at two or three islands before reaching your destination. Always check the flight duration—a 200-mile trip can take 5 hours if the plane stops twice.
Book at least 3 weeks out. Unlike domestic US or EU flights, Caribbean island-hopping flights rarely get cheaper last-minute. In fact, they often sell out due to limited seat capacity on small prop planes. Book as soon as your dates are locked.
