Which airlines fly between Caribbean islands?

Major regional carriers include LIAT (covers Eastern Caribbean), Caribbean Airlines (Trinidad-based, flies throughout region), interCaribbean Airways (based in Turks and Caicos), and Seaborne Airlines (Puerto Rico and US Virgin Islands). American Eagle and JetBlue also operate some inter-island routes.

Are inter-island flights reliable?

Weather delays are common, especially during hurricane season (June-November). Mechanical issues also cause delays since airlines have limited backup aircraft. Always build 4-6 hour buffers between connections and have flexible accommodation bookings.

Do I need to go through customs between islands?

Yes, each island is typically a separate country with its own customs and immigration, even for short flights. Allow 1-2 hours for check-in, security, and immigration processes at smaller airports.

Can I use frequent flyer miles for inter-island flights?

Limited options. American Airlines miles work for American Eagle routes. Caribbean Airlines partners with Copa Airlines for miles. Most regional carriers don't participate in major alliance programs, so cash is usually your only option.

How to Book Inter-Island Flights in the Caribbean

Book inter-island Caribbean flights through regional carriers like LIAT, Caribbean Airlines, or interCaribbean Airways. Use airline websites directly for best prices, book 2-3 weeks ahead for peak season, and expect to pay $150-400 per flight depending on distance and timing.

Identify your route and timing. Map out which islands you want to visit and in what order. Some routes have daily flights (like Barbados to Trinidad), others fly only 2-3 times per week. Check flight schedules before finalizing your itinerary since connections can add full days to your travel time.
Choose your booking method. Book directly through airline websites for the best prices and most flexibility. Regional carriers like LIAT, Caribbean Airlines, interCaribbean Airways, and Seaborne Airlines don't always show up on major booking sites, and when they do, prices are often higher.
Book 2-3 weeks ahead for peak season. For December through April travel, book flights 2-3 weeks in advance. For off-season (May through November), you can often book just days ahead, but hurricane season can cause last-minute cancellations so earlier is safer.
Consider multi-stop tickets. Caribbean Airlines and LIAT offer multi-destination passes that can save money if you're visiting 3+ islands. The Caribbean Airlines Multi-Destination Pass covers 12 destinations for around $450-650 depending on season.
Pack light and prepare for delays. Stick to carry-on if possible - baggage doesn't always make connections on inter-island flights. Weather delays are common, especially during hurricane season, so build buffer time between flights and have backup accommodation options.
