interCaribbean Airways is continuing its quiet but steady Caribbean build-out, adding another dot to its growing San Juan hub map just in time for the winter peak.
New San Juan – St. Kitts Route Starts December 18
Turks and Caicos–based interCaribbean Airways will launch new nonstop service between:
-
San Juan, Puerto Rico (SJU)
-
Basseterre, St. Kitts (SKB)
Service begins December 18 and will operate twice weekly, with a block time of around 1 hour 10 minutes in each direction.
Exact days and times will depend on the final timetable, but the aim is classic Caribbean leisure scheduling: easy weekend getaways and convenient connections to/from mainland US banks.
The flight will be operated by one of interCaribbean’s regional aircraft, consistent with the rest of its San Juan operation.
Here’s how CEO Trevor Sadler framed the move:
“This route marks another important step in our mission to connect the people and cultures of the Caribbean… we’re creating a vital link between two key Caribbean gateways, offering travelers fast and convenient access to major U.S. markets and enhanced Eastern Caribbean connectivity for both leisure and business travel.”
Why San Juan – St. Kitts Makes Sense
This isn’t just another sun route — it plugs a real connectivity gap:
-
San Juan (SJU) acts as a de facto mini-hub into the US mainland, with plentiful service from major US carriers.
-
St. Kitts (SKB) is a tourism-heavy island with limited nonstops, especially outside peak season, and most US access tends to be via a handful of hubs or Saturday-only flights.
By linking SKB to SJU, interCaribbean effectively gives St. Kitts:
-
One-stop access to a wide range of US cities
-
Better intra-Caribbean options without having to backtrack via large hubs like Miami
For interCaribbean, it’s another spoke in a growing network where short hops connect islands to a few key “super-nodes” (San Juan, Providenciales, etc.), instead of everyone relying on legacy long-haul carriers.
How This Improves Caribbean Connectivity
interCaribbean already uses San Juan (SJU) as a key gateway. From there it currently offers:
-
Nonstop: SJU – Tortola (EIS)
-
Same-airline connections via SJU to:
-
Antigua (ANU)
-
Barbados (BGI)
-
Dominica (DOM)
-
Providenciales (PLS) in Turks and Caicos
-
Adding St. Kitts (SKB) into that mix means:
-
SKB gains one-stop access to places like Antigua, Dominica, Barbados, and Turks and Caicos via San Juan and interCaribbean’s own metal.
-
Travelers from those islands now have an easier route into St. Kitts’ resorts and cruise-driven tourism market.
-
Passengers from St. Kitts can connect in SJU to major US carriers headed to cities across the mainland.
In other words, this isn’t just point-to-point — it’s another node in a web that makes island-to-island travel much more practical.
What It Signals About interCaribbean’s Strategy
This new route lines up neatly with interCaribbean’s broader play:
-
SJU as a northern hub: The airline keeps layering new Eastern Caribbean points onto its San Juan operation, making it more attractive to both regional travelers and US passengers willing to self-connect.
-
Filling the regional-connectivity gap: As some larger carriers pull back from short intra-Caribbean sectors, interCaribbean is stepping into that space with thinner, right-sized frequencies.
-
Tourism + VFR mix: St. Kitts offers a blend of resort traffic and visiting-friends-and-relatives (VFR) travel, which helps smooth seasonal swings.
If the route performs well, don’t be surprised to see additional frequency or further St. Kitts links (for example to Antigua or Barbados) down the line.
Bottom line
interCaribbean Airways will launch twice-weekly nonstop flights between San Juan (SJU) and St. Kitts (SKB) starting December 18.
The new route gives St. Kitts a valuable one-stop link into the US via SJU and slots neatly into interCaribbean’s growing Eastern Caribbean network, which already connects San Juan with Tortola, Antigua, Barbados, Dominica, and Turks and Caicos.
It’s a small step in absolute numbers, but an important one for regional connectivity — and another sign that interCaribbean intends to be a serious player in stitching the Caribbean together.
