Winair and Contour Open New Caribbean Routes

A new interline deal quietly reshaping how travelers move through the Eastern Caribbean

For anyone who has ever stared at a travel itinerary wondering how to stitch together a visit to Dominica, the US Virgin Islands, and Puerto Rico without losing half a vacation day to layovers and separate bookings, a quiet deal signed last month just made life considerably easier.

Winair — the venerable Dutch Caribbean carrier officially known as Windward Islands Airways — has formalized a new interline partnership with Contour Airlines, the fast-growing Tennessee-based regional carrier that has been making aggressive moves into the Caribbean over the past year. The agreement, which took effect in May 2026, allows Contour to sell tickets that include Winair-operated legs, meaning passengers can now book end-to-end itineraries across a much wider swath of the Caribbean on a single reservation.

For travelers, that distinction matters more than it might seem.

What the Deal Actually Means for You

Interline agreements are the unsung backbone of seamless travel. Without one, passengers flying two separate airlines must check in twice, collect and re-check bags, and absorb the full financial risk if a first flight runs late and they miss the second. With one in place, those friction points largely disappear — and crucially, travelers can book the whole journey in one go.

Under the Winair-Contour arrangement, the most significant gain for passengers is improved access to San Juan, Puerto Rico. Winair’s network stretches across the Eastern Caribbean, but Puerto Rico — the region’s largest air hub and a critical gateway for North American travelers — had previously been a patchwork of connections. Now, travelers on Winair’s routes can connect through Princess Juliana International Airport in St. Maarten directly onto Contour flights heading to San Juan, with that full itinerary bookable through Contour’s platform.

“This partnership represents another important milestone in expanding our network reach,” said Winair CEO Hans van de Velde. “By collaborating with Contour Airlines, we are making it easier for travelers to connect through St. Maarten and explore more destinations within our region.”

St. Maarten’s Quiet Rise as a Regional Hub

The deal also underscores a trend that has been building for some time: St. Maarten is no longer simply a destination in its own right — it’s increasingly functioning as the connective tissue of the Eastern Caribbean.

Princess Juliana International Airport, still recovering and rebuilding following the devastation of Hurricane Irma in 2017, has steadily reasserted its role as one of the busiest and most strategically placed airports in the region. Sandwiched between the French and Dutch sides of the island, SXM serves as a natural waypoint between North America and the smaller islands of the Leeward chain, and carriers like Winair have long used it as a central spoke in their hub-and-spoke operations.

The addition of Contour to that network gives the airport, and the island, another layer of commercial significance. As Caribbean tourism continues its post-pandemic expansion and travelers seek increasingly individualized itineraries — fewer one-resort package deals, more multi-island adventures — the ability to route efficiently through St. Maarten becomes a genuine competitive advantage for the destination.

Contour’s Caribbean Buildout: Fast and Deliberate

For those unfamiliar with Contour, the airline’s rise in the Caribbean has been one of the more compelling aviation stories of the past twelve months.

The carrier only launched its first Caribbean routes in late summer 2025, opening with service from San Juan and St. Thomas to Dominica — routes that gave the Nature Isle its only nonstop jet links to both Puerto Rico and the US Virgin Islands. It was a bold entry point: Dominica, long overshadowed by its larger neighbors in the tourism conversation, has been working hard to position itself as an eco-luxury destination, and reliable, convenient air access has historically been one of its biggest stumbling blocks.

Contour then added flights between San Juan and St. Maarten, currently operating three times per week on its 30-seat jets. That small but agile fleet is a deliberate choice — regional Caribbean routes rarely generate the passenger volumes that justify mainline aircraft, and right-sized equipment means carriers can profitably serve routes that larger airlines would ignore.

With this latest Winair interline agreement, Contour now has what amounts to a turnstile into the broader Eastern Caribbean network. The Tennessee airline now serves more than 30 destinations across the United States and the Caribbean — and earlier this year struck a separate interline deal with JetBlue, which opened that carrier’s network of more than 100 destinations to Contour passengers. The logic is clear: Contour is building itself into an indispensable bridge between the US mainland and the Caribbean’s smaller islands.

“We are excited for our new partnership with Winair,” said Ben Munson, President of Contour Airlines. “Contour passengers will now have the ability to connect onto Winair’s impressive network beyond St. Maarten throughout the Caribbean.”

Why Dominica Stands to Gain the Most

Of all the destinations touched by this agreement, Dominica may have the most to gain.

The island — distinct from the Dominican Republic to its northwest — has long been one of the Caribbean’s best-kept secrets and most frustrating travel logistical puzzles. Rainforest-covered, volcanically active, and home to some of the most dramatic hiking and diving in the hemisphere, Dominica has spent years cultivating an eco-tourism identity that sets it apart from the beach-and-pool circuit. The Waitukubuli National Trail, stretching the entire length of the island, is the longest hiking trail in the Caribbean. Its boiling lake, Champagne Reef, and whale-watching waters are genuinely world-class.

What Dominica has lacked is the air infrastructure to match its ambitions. Melville Hall Airport, the island’s main international gateway, handles turboprop services from neighboring islands and select jet routes — but it has never offered the kind of seamless U.S. connections that fill hotels and resorts on larger islands.

Contour’s San Juan–Dominica route changed that calculus when it launched last year. Now, with the Winair interline link added, travelers arriving in St. Maarten from anywhere on Winair’s regional network can also connect to Dominica via Contour — and vice versa. The island’s tourism ecosystem, from the luxury Cabrits Resort & Spa to small-scale rainforest lodges, stands to benefit from every marginal improvement in access.

The Traveler Takeaway

Practically speaking, what does this partnership mean for someone planning a Caribbean trip?

If you’re routing through San Juan or St. Thomas — both easily reachable from dozens of U.S. cities — the Contour-Winair link opens up onward connections to Dominica and the broader Winair network without the hassle of separate bookings. Island-hopping itineraries that once required careful timing and separate tickets can now flow more naturally through a single reservation.

For travelers based in the Eastern Caribbean, the reverse applies: the road to Puerto Rico, and from there to Contour’s growing U.S. network, just got smoother.

It’s also worth noting the timing. Caribbean travel demand continues to outperform pre-pandemic benchmarks, and the region’s challenge is no longer simply attracting visitors — it’s distributing them across a wider range of destinations. Partnerships like this one, which make the smaller, less-developed islands more accessible, are precisely the mechanism by which places like Dominica can capture a larger share of Caribbean tourism spend.

If the trajectory of both airlines is any guide, this interline agreement is unlikely to be the last piece of news from either carrier in 2026. Contour has shown a pattern of rapid network expansion followed by strategic commercial partnerships — the JetBlue deal being the most prominent example — and Winair has every incentive to deepen its connections to the US market as Caribbean tourism continues to evolve.

St. Maarten, sitting at the center of both networks, stands to reap the rewards. So does Dominica. And so, most importantly, do the travelers for whom the Eastern Caribbean’s smaller islands have always been the most rewarding — just occasionally the most complicated to reach.

That’s changing, and deals like this one are the reason why.
