Aer Lingus has record North American capacity; it has added 9 cities since 2023

North America is a growing part of Aer Lingus’ network. According to Cirium schedule information, 3.8 million two-way seats are available in 2025. The US accounts for 96% of the total.

Capacity to/from North America has increased by almost 6% compared to the prior high, and by over a quarter versus what was available before the pandemic in 2019.

When all of Aer Lingus’ network is considered, its total seat growth was 1% year-on-year and virtually flat compared to 2019. Consequently, North America has risen to represent 22% of its overall capacity.

Dublin has 84% of Aer Lingus’ North American seats

Aer Lingus serves North America from three European airports: Dublin (84% of 2025 seats), Manchester (10%) and Shannon (6%). Its first transatlantic service from Manchester was in 2021, which materialised because of the big capacity gap that resulted from airline cessations and others pulling out.

Inevitably, its growth has, of course, mainly been from its Dublin hub. It is the first year that its US/Canada seats have collectively passed three million from the Irish capital.

The A321LR and A321XLR have been critical to its transatlantic development, including in terms of adding new cities to its network and freeing up widebodies on some routes, which can then be used elsewhere.

In 2023, Aer Lingus added Cleveland (A321LR) and Hartford (A321LR). In 2024, flights began to Denver (A330) and Las Vegas (A330), while it returned to Minneapolis (A321). In 2025, Indianapolis (A321) and Nashville (A321) welcomed their first Irish flight. In 2026, it will begin flying to Cancun (A330) and Raleigh/Durham (A321).

New York JFK has one in five seats

With 791,000 two-way seats, New York JFK is Aer Lingus’ leading North American market, with more than a fifth of capacity to that airport. This is partly because it is served from Dublin, Shannon and Manchester. It is the only place to have flights from all three European airports.

In July 2025, Aer Lingus has 4-daily departures to JFK: 2-daily from Dublin and daily from both Shannon and Manchester. In July 2026, it will rise to 5-daily: 3 from Dublin and daily from Shannon and Manchester.

Of other incumbent routes, Dublin-Boston will rise from 2-daily to a record 18-weekly, while Shannon-Boston will grow from daily to 10-weekly. Elsewhere, Dublin to Cleveland and Orlando will increase from 6-weekly to daily, while Indianapolis and Nashville will rise from 4-weekly to 5.
