Airlines Push Long-Haul Route Boundaries With New City Pairings

A wave of new long-haul routes launching before the end of the year reveals where airlines see untapped demand. Air Canada and United are sending widebody aircraft to Sapporo, a northern Japanese city that has rarely featured in long-haul network plans. The additions signal a growing appetite for secondary destinations with potential for both business and leisure travel.

In the Australia market, two European carriers are adopting Turkish Airlines' one-stop Melbourne playbook, adding more options for travelers between Europe and the Australian city. The strategy builds on the success of using a hub as a stepping stone rather than flying a direct route, which can be riskier on thinner demand.

Delta is opening the first U.S. nonstop service to Riyadh, Saudi Arabia, entering a market that its transatlantic partner previously tried and left. The new route gives Delta a first-mover advantage in the U.S.-Saudi corridor, though the partner's earlier exit underscores the challenges of sustaining service there.

Las Vegas also appears among the new long-haul pairings, with airlines testing the city's pull as a leisure and events destination for international travelers. The route choices reflect a broader shift toward using fuel-efficient widebody jets to make previously marginal city pairs viable.

Each of these routes is the culmination of months of market research and financial analysis before it appears on the departure board. Industry executives acknowledge the bets carry real risk: none of the launches are cheap, and not every new pairing will generate enough demand to become permanent.
