Foreign-registered private jet operators are rerouting Caribbean-bound flights through third-country fuel stops and exploiting regulatory gaps in airspace enforcement, creating a $2,800–$3,200 per-leg cost differential compared to direct routing. The workaround follows intensified enforcement of decades-old bilateral aviation agreements that restrict non-U.S. carriers from certain Caribbean commercial operations.

The pattern emerged after Antigua, Barbados, and Jamaica tightened enforcement in Q4 2024, requiring foreign operators to secure commercial air service permits for charter flights—a process taking 14–21 days and involving per-flight fees of $1,500–$2,800. Operators responded by adding technical fuel stops in Bermuda, Providenciales, and Grand Cayman, where enforcement remains lighter and fueling infrastructure welcomed the volume. A Gulfstream G650 traveling London–Barbados now typically stops in Bermuda, adding 47 minutes of flight time but avoiding permit delays and reducing total trip cost by 18–22 percent when factoring standby fees and positioning costs.

The arbitrage matters because it shifts where fuel dollars land and which FBOs capture handling revenue during the winter charter season. Signature Flight Support's Providenciales location reported 34 percent year-over-year handling increases in January 2025, while St. Maarten and Antigua saw declines of 19 percent and 11 percent respectively. Fuel margins in the Turks and Caicos run $0.40–$0.65 per gallon higher than larger Caribbean hubs, but operators absorb the difference to maintain schedule flexibility and client anonymity—permit applications require beneficial owner disclosure in several jurisdictions.

The routing shift also creates secondary effects in ground handling and crew positioning. European operators are pre-positioning crews in Bermuda on 72-hour rotations rather than flying them roundtrip per charter, reducing labor costs but increasing fixed overhead. One Swiss operator now maintains two full crews in Bermuda year-round to serve Caribbean demand, a staffing model previously reserved for operators with 20-plus aircraft. Caribbean hotel occupancy in crew-rate categories fell 8 percent in January while Bermuda saw a 12 percent increase, according to STR data.

Operators and allocators should monitor bilateral aviation negotiations between CARICOM states and the EU scheduled for Q2 2025, which could either codify restrictions or create carve-outs for sub-12,000-pound aircraft. Fuel infrastructure investment in Providenciales and Grand Cayman is accelerating—two FBO expansions totaling $47 million broke ground in January. Permit processing times in Antigua have already shortened to 9–11 days as fee revenue funds additional administrative staff.

The routing patterns are now stable enough that flight planning software providers added Bermuda and Providenciales as default Caribbean waypoints in February updates. That makes the workaround infrastructure, not improvisation.
