Citi and Panmure Liberum have both flagged significant undervaluation in International Consolidated Airlines Group SA (LSE:IAG) following the carrier's Loyalty Day investor presentation, where management set a medium-term earnings target of €1 billion for its loyalty division. The loyalty business generated €593 million in earnings before interest and tax in 2025, implying near-doubling is required to hit the new target, though IAG set no specific timeframe for achieving it.
