Why Did WestJet Cut These 24 Routes to the US and 14 Routes to the Caribbean?

WestJet Airlines (WS) has eliminated 41 international routes from its network when comparing its January 2025–May 2026 schedule against forward bookings spanning June 2026 to March 2027 — the most consequential single-season network contraction the Calgary-based airline has undertaken in recent years, Simple Flying reported.

According to analysis from aviation data platform OAG cited by Simple Flying, WestJet currently accounts for nearly one-fifth (approximately 19 percent) of all flights in Canada in 2026, with a domestic market share of 22 percent but a considerably thinner slice of long-haul international operations at just 7 percent of Canada’s long-haul flying.

Political Tensions Drained Canada–US Air Demand

The United States absorbs the largest share of WestJet’s network cuts by a considerable margin: 24 of the 41 eliminated routes — 57 percent of the total — involve transborder Canada–US flying. The scale of this withdrawal reflects a structural erosion in demand rather than a tactical schedule adjustment. WestJet spokesperson Julia Kaiser confirmed to Global News that the airline experienced “a notable decline in transborder travel demand throughout 2025” and stated that the carrier was reducing its full-year US flying by approximately 10 percent, with a 15 percent reduction during what were “historically peak” summer travel periods.

Aggregate data confirms the severity of the downturn. According to Statistics Canada, return trips by Canadians to the United States fell by 23.6 percent in late 2025. US Department of Transportation (DOT) data covering WestJet’s own passengers found that the carrier’s US traffic between March 2025 and February 2026 ran 19 percent lower than in the preceding 12 months. When measured in Available Seat Miles — the metric that accounts for both seat count and distance flown — WestJet’s US capacity for Summer 2026 fell by approximately 32 percent compared with its earlier schedule submission, representing one of the most significant single-season corrections in the airline’s history.

Among the most commercially interesting individual route eliminations is WestJet’s withdrawal from Winnipeg James Armstrong Richardson International Airport (YWG) to Hartsfield-Jackson Atlanta International Airport (ATL). WestJet had operated this service from September 2023 to April 2026, primarily to feed codeshare partner Delta Air Lines (DL) at its dominant Atlanta hub.

Despite the unparalleled network connectivity available at ATL, WestJet managed only a 79.0 percent load factor on the route. Other US routes removed include:

• Vancouver International Airport (YVR) to Boston Logan International Airport (BOS), served June to October 2025
• Calgary International Airport (YYC) to Raleigh-Durham International Airport (RDU), served June to October 2025
• Edmonton International Airport (YEG) to Nashville International Airport (BA), served May 2024 to October 2025
• YWG to BNA
• YVR to Tampa International Airport (TPA), last operated in October 2025.

Cuba’s Geopolitical Fuel Crisis Cuts WestJet’s 14 Caribbean Route

All 14 of WestJet’s eliminated Caribbean routes involve Cuba, and every single one is a direct inheritance from the carrier’s 2023 acquisition of Sunwing Airlines — itself one of Canada’s pre-eminent leisure operators in the Cuban market for decades. The backstory is as much geopolitical as commercial.

Cuba is, by a considerable margin, the most popular Caribbean winter-sun destination for Canadians; at the height of the Sunwing era, multiple Canadian airports maintained seasonal direct services to Varadero, Cayo Coco, Holguín, Santa Clara, and Havana. These routes were a cornerstone of the leisure business WestJet was attempting to inherit and grow when it completed the Sunwing acquisition in May 2023.

In early February 2026, that business was abruptly and entirely suspended. Cuba’s major airports warned that Jet A-1 aviation fuel was critically depleted, a consequence of geopolitical forces far beyond the airline’s control. The Trump administration’s blocking of Venezuelan crude oil shipments — Cuba’s primary fuel source — combined with Mexico’s suspension of its own supplies to the island to avoid punitive US tariffs, left Cuba without meaningful aviation fuel.

January 2026 marked the first month since 2015 in which Cuba received no oil shipment whatsoever. The result was nationwide blackouts, civilian fuel shortages, and the complete commercial inviability of operating scheduled passenger services to Cuban airports.

WestJet, along with Air Canada (AC), Air Transat (TS), and the full Sunwing Vacations Group, began suspending operations on February 9–10, 2026. WestJet Group stated it would dispatch empty aircraft to Cuba to repatriate approximately 3,000 Canadians then vacationing on the island, and that “all aircraft dispatched to Cuba will carry sufficient fuel to safely depart without reliance on local fuel availability.”

Routes to Mexico and a Colombian Caribbean Island Also Axed

Beyond the US and Cuba, WestJet has eliminated three additional routes spanning Mexico and Colombia.

Two of the cuts involve Mexico — a market that now represents WestJet’s second-largest international country destination after the US. Mexico accounted for 16 percent of WestJet’s flights in 2022, a figure that has grown to 27 percent in 2026 following the full absorption of Sunwing’s Mexico-heavy leisure network.

The third cut is more unusual. WestJet had operated a service between YUL and El Embrujo Airport on San Andrés Island (ADZ), a Colombian territorial possession located geographically in the Caribbean and culturally distinct from mainland Colombia, from December 2025 to March 2026.

The route was inherited directly from Sunwing, which maintained seasonal leisure service to San Andrés as a Cartagena-adjacent alternative popular with Quebec-based tour operators. WestJet has not scheduled a replacement, and the San Andrés market will be unserved by Canadian carriers for the foreseeable future.

All in All

The practical consequence of WestJet’s 41 route eliminations — particularly the 24 US cuts — is a meaningful reduction in nonstop connectivity for passengers in secondary and mid-size Canadian cities.

Travel Pulse Canada notes that Edmonton International Airport and Vancouver International Airport are the hardest-hit airports by the cancelled US routes, with multiple routes eliminated from each hub. Key routes in overlapping markets continue to be served by Air Canada and other carriers:

• Toronto–Las Vegas remains available through Air Canada and United Airlines
• Vancouver–San Francisco retains multiple daily departures with Air Canada and United
• Toronto–Los Angeles continues to be heavily served.

However, for the secondary routes from secondary cities, there is now significantly less choice.
