Aer Lingus Teoranta was established in 1936 as Ireland’s national airline. The name “Lingus” is derived from the Irish word “loingeas” meaning fleet. The airline’s first aircraft, named “Iolar” (Eagle), took its inaugural flight on May 27, 1936, from Baldonnel Aerodrome near Dublin to Bristol, England. This modest beginning launched what would become one of Europe’s most recognizable carriers.
In the post-World War II era, Aer Lingus experienced significant expansion. During the late 1940s and early 1950s, the airline introduced routes to Brussels, Amsterdam via Manchester, and Rome. This period also saw the company modernize its fleet with the acquisition of Vickers Viscount 700 turboprop airliners in 1954, making Aer Lingus one of the early adopters of this advanced aircraft.
A pivotal moment came on April 28, 1958, when Aerlinte Eireann established the first transatlantic service from Shannon to New York. The company officially adopted the Aer Lingus name for all operations in 1960. That same year marked the airline’s entry into the jet age with the introduction of Boeing 720 aircraft on routes to New York and Boston.
Through the decades, Aer Lingus continued to evolve its fleet and route network. The airline began operating Airbus aircraft in 1994, starting with the A330 on its transatlantic routes, which led to the eventual phasing out of its Boeing 747 fleet. By 2006, Aer Lingus had transitioned to an all-Airbus fleet.
Once fully state-owned, the Irish government began reducing its stake in the airline in 2006. Aer Lingus became a wholly owned subsidiary of International Airlines Group (IAG) in 2015, joining British Airways and Iberia under the same corporate umbrella. Despite this change in ownership, Aer Lingus maintains its distinctive Irish identity and continues to serve as Ireland’s flag carrier.
Stats and Quick Facts
Aer Lingus has grown from a single aircraft operation to a significant European carrier. Today, the airline operates 60 aircraft serving over 90 routes to destinations in the UK and Europe, plus 23 direct routes to North America. The airline carries more than 11 million passengers annually.
The airline holds a prestigious 4-Star rating from Skytrax, the international air transport rating organization, making it Ireland’s only 4-Star airline. This recognition highlights the carrier’s commitment to quality service.
Aer Lingus is known for its distinctive green livery and the iconic shamrock symbol, representing its Irish heritage. The shamrock first appeared on the tail of their aircraft in the late 1950s and remains a key part of their visual identity today.
The current Aer Lingus fleet consists primarily of Airbus aircraft. Its short-haul operations utilize Airbus A320s and A321s, while long-haul routes are served by Airbus A330s. The airline continues to modernize its fleet with orders for next-generation aircraft like the Airbus A321XLR.
Hubs and Network
Aer Lingus operates a hub-and-spoke network centered primarily on Dublin Airport, which serves as the airline’s main base for nearly all transatlantic and international flights. Dublin also functions as the carrier’s primary maintenance facility.
Secondary hubs play important roles in the Aer Lingus network. Cork Airport remains important for Aer Lingus despite a reduction in operations in recent years, with several aircraft based there serving routes to the UK and Europe.
Shannon Airport serves as a secondary hub for transatlantic connections, with Aer Lingus operating short-haul flights to London-Heathrow and Paris-Charles de Gaulle that feed their daily transatlantic flights to Boston and New York-JFK.
The airline has developed a particularly strong presence in the transatlantic market. Aer Lingus serves destinations across Europe, North America, and Northern Africa, offering both economy and business class services. Their extensive network connects Ireland to major cities worldwide, leveraging Dublin’s strategic location as a natural gateway between Europe and North America.

The Future of Aer Lingus
As part of the International Airlines Group (IAG), Aer Lingus is positioning itself for future growth while addressing aviation industry challenges.
Fleet Modernization: At the 2019 Paris Air Show, IAG agreed to purchase 14 Airbus A321XLR aircraft, with six designated for Aer Lingus, with deliveries scheduled to begin in 2025. These next-generation aircraft will enable Aer Lingus to operate longer routes with greater fuel efficiency.
In June 2022, Aer Lingus signed a lease agreement for two new Airbus A320neo aircraft, which deliver up to 20% reduction in fuel burn and CO2 emissions compared to previous generation aircraft, along with a nearly 50% reduction in noise footprint.
Sustainability Initiatives: Environmental responsibility is becoming increasingly central to Aer Lingus’s future plans. As part of IAG, Aer Lingus has pledged to achieve net zero carbon emissions by 2050 and has committed to powering 10% of its flights using sustainable aviation fuel (SAF) by 2030.
To advance this goal, Aer Lingus and British Airways (through parent company IAG) signed an agreement with Aemetis, Inc. in August 2022 to supply sustainable aviation fuel for flights from San Francisco Airport starting in 2025. This multi-year partnership represents a significant step toward reducing the airline’s carbon footprint.
In November 2024, IAG announced a 10-year purchase agreement with Infinium for sustainable aviation fuel, which can be supplied to any of IAG’s airlines including Aer Lingus. These partnerships demonstrate the airline’s commitment to embracing alternative fuels.
Other sustainability initiatives include replacing plastic cutlery with sustainable birch wood alternatives, introducing digital alternatives to printed newspapers and magazines, implementing fuel-saving operational procedures, and expanding the use of electric ground vehicles.
Route Development: Aer Lingus continues to expand its network, particularly across the Atlantic. In October 2024, Aer Lingus announced plans to launch a new non-stop direct route between Dublin and Indianapolis beginning May 3, 2025, offering four flights per week using its Airbus A321XLR aircraft. This route represents the airline’s commitment to expanding its North American presence.
Competitive Positioning: Within IAG’s portfolio of airlines, Aer Lingus faces both opportunities and challenges. Recent reports have described Aer Lingus as having weaker performance compared to other IAG carriers, with both the lowest operating profit and the lowest operating profit margin among the group’s airlines. This suggests that improving financial performance will be crucial for the airline’s future within IAG.
Despite these challenges, Aer Lingus continues to define its unique market position. The airline’s mission is “to become the leading value carrier operating across the North Atlantic enabled by a profitable and sustainable short-haul network, and supported by a guest-focused brand and a digitally-enabled value proposition.” This vision combines competitive pricing with quality service, distinguishing Aer Lingus from both premium and ultra-low-cost carriers.
