Aer Lingus expands summer network with new European routes and transatlantic growth

Aer Lingus is ramping up its summer 2026 operations with the launch of three new European routes and the return of several seasonal destinations, alongside continued expansion of its transatlantic network.

The airline will inaugurate new short-haul services from Cork to Nice, as well as from Dublin to Oslo and Asturias. These additions aim to strengthen Aer Lingus’ European leisure offering at the start of the peak travel season.

At the same time, the carrier is reinstating a number of popular summer routes from Dublin, including flights to Pisa, Catania, Nantes, and the Greek islands of Santorini and Corfu, broadening options for holiday travellers across Europe.

Further expansion is planned in the coming weeks, with additional new routes from Dublin to Montpellier and Tours, as well as from Cork to Santiago de Compostela. Regional connectivity will also improve with a new service to Inverness, operated by Emerald Airlines.

On long-haul routes, Aer Lingus is resuming its Dublin–Denver service for the summer, complementing newly introduced connections to Raleigh–Durham and Pittsburgh. The airline will operate 24 routes between Ireland and North America in 2026, reinforcing its Dublin hub strategy and facilitating transatlantic connections.

The expansion reflects sustained demand for both European leisure travel and North American connectivity, as Aer Lingus continues to position itself as a key bridge between the two regions during the busy summer season.
