Aer Lingus’ recovery is almost complete; added 19 routes since March 2023, including to the US


Aer Lingus is Europe’s twenty-third largest airline by available seats in the first half of 2024 (January-June), based on Cirium schedules data. Its network is from the Republic of Ireland, Belfast BHD in Northern Ireland, and, through its Aer Lingus UK AOC, from Manchester. shows that Aer Lingus itself has 54 A320s/A321s/A330s, its Regional unit (operated by Emerald Airlines) has 17 ATR 72s and Aer Lingus UK has two A330s. In all, there are 73 aircraft.

Capacity remains down versus 2019, but 19 routes introduced

Cirium shows that Aer Lingus’ 1H capacity has risen by about 7% year-on-year. Yet it has not quite recovered from the pre-pandemic 2019, with seats still down by a modest 1%.

Its recovery has benefited from 19 new and returning routes that started in 2023 or will do so in the first six months of 2024. The most notable are three to the US: Cleveland, Minneapolis (returning, having been served between June 2019 and April 2020) and Denver. The frequencies are based on the week each route began.

Aer Lingus development first half 2014-2024

London LGW exits its network soon

Aer Lingus first served London LGW 17 years ago in 2007 with one route from Dublin. Two years later it opened a short-lived base at the UK’s second-busiest airport with 14 routes, reduced to five routes by 2011 and two in 2017.

As Aer Lingus consolidated at LHR, including shifting its Knock route to the airport, LGW returned to being a one-route operation – Dublin – in April 2023. Its last flight will leave on 30 March. In the following week, Ryanair will have 52-weekly Dublin-LGW flights.

Aer Lingus serves 98 destinations on a scheduled basis

Aer Lingus plans to serve 98 destinations in Europe and North America between January and June 2024. Twenty airports are served in the UK (including LGW), 15 in the US, 11 in Spain, and 10 in both France and Italy. There are 123 scheduled routes, which are broken down as follows:

  • 91 from Dublin (Aer Lingus and Regional), including its sole domestic Republic of Ireland route to Donegal
  • 14 from Belfast BHD (Regional)
  • 11 from Cork (mainly Aer Lingus but also Regional)
  • Four from Shannon (Aer Lingus)
  • Two from Manchester (UK AOC, excluding routes to/from Ireland)
  • One from Knock (Aer Lingus)

Despite routes from other airports, Dublin accounts for about 80% of available seats. It has about a third of all seats in the Irish capital, meaning it is second only to Ryanair (45%) – Aer Lingus is first by ASKs because of its long-haul operation. Aer Lingus is also second to the ULCC at Cork, Shannon and Knock.

TOP 10 Aer Lingus airports first half 2024

Dublin-London LHR is the leading route

Given so much of Aer Lingus’ capacity is deployed to, from and in the UK, it should not be surprising that half of its top 10 routes involve the UK. Perhaps you would expect more. In June, Aer Lingus will serve Dublin-London LHR 107-weekly, with a maximum of 17-daily flights. Close partner British Airways itself will have 40-weekly flights on his airport pair.

Three routes that were in the top 10 in the first half of 2019 are no longer: Dublin-LGW (ending), Dublin-Chicago ORD and Belfast BHD-London LHR (switched to BA).
