Morgan Stanley initiates IAG stock with Overweight rating, cites Heathrow dominance

Morgan Stanley initiated coverage on International Consolidated Airlines Group SA (IAG) with an Overweight rating and a GBP5.50 price target, citing the airline's dominant position at London Heathrow and resilient premium demand. The firm anticipates IAG will expand its profitable transatlantic market share, supported by cost transformation and new aircraft, projecting FY25 EBIT 6% above consensus due to potential pricing strength and lower fuel costs. This positive outlook, coupled with robust cash generation and a solid balance sheet, is expected to drive a rerating of IAG shares above historical averages.

Analysis

Morgan Stanley initiated coverage on International Consolidated Airlines Group SA (IAG) with an Overweight rating and a GBP5.50 price target, signaling a strong bullish outlook. This positive stance is primarily driven by IAG's dominant position at London Heathrow, where it controls over half the slots, providing access to a critical premium and corporate travel hub. This strategic advantage supports resilient premium demand, offsetting softer U.S. leisure trends.

The investment bank anticipates IAG will expand its share in the profitable transatlantic market, benefiting from limited competition at Heathrow and sustained pricing power. Furthermore, cost transformation efforts, the introduction of new-generation aircraft like the A321XLR, and customer experience reinvestment are expected to significantly improve margins.

Morgan Stanley's FY25 EBIT estimate stands 6% above consensus for both 3Q25 and FY25, citing potential upside from stronger pricing, lower fuel costs, and better unit cost performance. Beyond 2025, fleet renewal and digital initiatives are projected to further reduce costs, supporting strong margins and returns on capital.

The firm highlights robust cash generation, a solid balance sheet, and enhanced shareholder returns as catalysts that could lead to a rerating of IAG shares above historical averages. This comprehensive positive outlook underpins the Overweight recommendation.

Key Decisions for Investors

• Investors should consider initiating or increasing a long position in IAG, given Morgan Stanley's Overweight rating and positive catalysts.
• Monitor IAG's progress on transatlantic market share expansion and cost transformation initiatives, as these are key drivers for margin improvement.
• Assess IAG's valuation against historical averages and peer multiples, as robust cash generation and enhanced shareholder returns could lead to a rerating.
