IAG — Aviation Cycle

International Airlines Group (IAG) is the parent company of British Airways, Iberia, Vueling, Aer Lingus and LEVEL — operating approximately 600 aircraft across short-haul European and long-haul international routes from its London Heathrow, Madrid Barajas and Dublin hubs. IAG is Europe's third-largest airline group by revenue and the most leveraged major airline to the transatlantic premium cabin travel market.

Transatlantic: The Profit Engine

British Airways' North Atlantic network — London Heathrow to New York, Boston, Miami, Chicago, Los Angeles — generates the majority of IAG's profits. Premium cabin (business and first class) transatlantic yields are among the highest in global aviation. Post-COVID demand recovery drove transatlantic premium yields to record levels as pent-up corporate travel and leisure demand overwhelmed capacity. This transatlantic franchise is IAG's most valuable and defensible asset.

British Airways: The Premium Brand

British Airways serves as IAG's premium long-haul brand — with Club Suite business class among the most award-winning products in global aviation. The Heathrow slot portfolio — among the world's most valuable airport slots — provides structural competitive protection as Heathrow operates at near-capacity. These slots cannot be replicated by new entrants and underpin BA's long-haul route franchise.

Iberia and Vueling: The Southern European Platform

Iberia's Latin American network — connecting Spain to Brazil, Mexico, Colombia, Argentina — provides route diversification and access to growing Latin American business travel. Vueling's short-haul Spanish and Mediterranean network provides feeder traffic to Iberia's long-haul flights and captures European leisure travel growth. Together, the Spanish operations contribute significant EBITDA alongside the UK-based operations.

Fuel Hedging: Managing the Brent Cycle

IAG uses jet fuel hedging to manage its Brent crude exposure — typically hedging 50–75% of fuel requirements 12 months forward. This hedging strategy smooths fuel cost changes but creates complexity: when Brent falls sharply, hedged carriers lose the benefit of spot price reductions, while unhedged carriers immediately benefit. The hedge position at any point in time is a critical variable for modelling IAG's near-term earnings.

Key Risks

Brent crude is the dominant external cost variable — jet fuel represents 25–30% of operating costs. Air traffic control strikes (particularly in France and the UK) cause costly flight cancellations. Heathrow capacity constraint limits traffic growth. British Airways IT systems and industrial relations with cabin crew unions create periodic operational disruption. Sterling weakness reduces the GBP value of non-UK revenues.
