International Consolidated Airlines Group stock (ISIN ES0177542018) was trading at GBp 431.40 on the London Stock Exchange on September 23, 2026, down 1.75 percent from the previous close. The price stood 12.48 percent below its 52-week high of GBp 492.90, putting the current market value at GBP 18,998,140,924.

Profit pressure shapes 2026

The latest operating picture combines higher sales with weaker profit conversion. According to Invezz on September 9, 2026, first-half revenue rose 1 percent to EUR 16 billion, while operating profit fell to EUR 1.75 billion from EUR 1.8 billion in the same period of 2025.

The comparison implies a EUR 50 million decline in operating profit despite revenue growth. The same report put the first-half operating margin at 10.9 percent, a figure that helps explain why fuel costs remain central to the airline groups earnings profile.

Capacity stays flat

Morningstar reported on September 23, 2026, that British Airways plans to increase Latin America seat capacity by 25 percent in summer 2027. The expansion includes daily nonstop service between London Heathrow and Buenos Aires plus additional capacity to Brazil, Chile and Costa Rica.

Morningstar also said IAG reduced its 2026 capacity guidance to flat after second-quarter operating profit declined 16 percent, while retaining a 12 percent to 15 percent operating margin target. That contrast makes network allocation more important than simple capacity growth.

Buyback supports capital returns

IAG completed another EUR 500 million buyback in September, bringing completed repurchases to EUR 1 billion of a EUR 1.5 billion excess cash return plan, according to The Globe and Mail on September 18, 2026. The latest tranche covered 97,747,488 shares, equal to 2.12 percent of issued capital.

The market is therefore weighing two opposing figures: a EUR 1 billion capital return against a 16 percent second-quarter operating profit decline. For investors, the next evidence will come from whether targeted long-haul growth can improve profit quality while capacity remains flat.
