Airlines are expanding their networks with a series of new long-haul routes launching in May 2026. The new services include multiple transatlantic additions from U.S. and Canadian airports.
Alaska Airlines is adding Seattle-London Heathrow and Seattle-Reykjavik service, while also launching Seattle-Rome and Seattle-Barcelona flights. Delta is introducing seasonal service from Boston to Madrid and Nice, along with summer routes from New York JFK to Olbia and Porto.
American Airlines is also expanding in Europe with new seasonal service from Philadelphia to Budapest and Prague, plus Dallas/Fort Worth-Athens and summer service to Zurich. JetBlue is adding Boston-Milan Malpensa, Aer Lingus is launching Dublin-Pittsburgh, and Finnair is returning to Canada with Helsinki-Toronto service.
The list shows a wider push by airlines to rebuild and broaden international networks heading into the summer season. Several of the routes are described as seasonal, suggesting they are aimed at peak travel demand.
What this means for you
Travelers looking for nonstop or one-stop options to Europe may find more choices on North American carriers this summer. New routes can also create better pricing, more schedule options, and easier connections from secondary cities.
Because many of the services are seasonal, availability may be limited to specific travel windows. Anyone planning a trip should check operating dates before booking.
These route launches also matter for travelers in Canada and the U.S. who want more direct links to Europe. The new network choices may reduce the need to connect through larger hubs.
The expansion underscores continued airline interest in Europe-bound demand. For passengers, the biggest change is simply more nonstop options in more city pairs.
