International Consolidated Airlines Group, S.A. (IAG) is a leading global airline holding company, formed in January 2011 through the strategic merger of British Airways and Iberia. Headquartered in London, IAG’s primary mission is to provide safe, reliable, and customer-focused air travel across a network of more than 270 destinations spanning six continents.
At the core of IAG’s success is its diversified portfolio of airlines—British Airways, Iberia, Aer Lingus, Vueling, LEVEL, and IAG Cargo—each operating with a distinct market positioning:
- British Airways: Flag carrier of the United Kingdom founded in 1974, renowned for its premium long-haul services, extensive route network, and loyalty program. In 2024, British Airways transported over 30 million passengers and contributed £12.5 billion to group revenues.
- Iberia: Spain’s flagship airline with origins dating back to 1927. Specializing in Europe–Latin America routes, Iberia carried 15 million passengers in 2024 and generated revenues of €4.2 billion, leveraging its Madrid hub for seamless connectivity.
- Aer Lingus: Ireland’s national carrier, founded in 1936, with an emphasis on transatlantic services. In 2024, Aer Lingus grew capacity by 8%, adding four new US routes and carrying 10 million passengers, contributing €3.1 billion to group revenues.
- Vueling: Established in 2004 as a low-cost European carrier, Vueling now serves over 140 short-haul city pairs. It achieved a load factor of 91% in 2024, carried 20 million passengers, and delivered €2.8 billion in revenue through competitive pricing and ancillary sales.
- LEVEL: Launched in 2017 and focused on long‑haul leisure travel, LEVEL operates from Barcelona and Paris, serving 10 destinations in North America and the Caribbean. In its seventh year, LEVEL carried 3 million passengers and posted revenue of €1.5 billion.
- IAG Cargo: IAG’s dedicated freight division established in 2011, transporting 1.2 million tonnes of cargo in 2024. It provides tailored solutions for pharmaceuticals, perishables, and e-commerce, generating €1.2 billion in revenue.
Across all brands, IAG employed 62,000 full‑time equivalents at year‑end 2024, maintaining rigorous safety standards with zero major safety incidents reported. The Group’s robust operational performance is supported by key hubs in London Heathrow, Madrid Barajas, Dublin, and Barcelona El Prat.
In 2024, IAG modernized its fleet, introducing 20 state‑of‑the‑art Airbus A350s and Boeing 787 Dreamliners across its long‑haul network. It also invested €150 million in digital transformation, upgrading its mobile app and implementing AI‑driven revenue management tools to optimize pricing and network planning.
With a commitment to sustainability, IAG set a target to achieve net zero carbon emissions by 2050, investing €200 million in sustainable aviation fuel (SAF) partnerships and launching a carbon offset programme for customers.
This comprehensive profile establishes IAG as a diversified, resilient, and forward‑looking airline group, uniquely positioned to capitalize on global travel demand while driving long‑term shareholder value.
