International Consolidated Airlines Group (LSE: IAG) has delivered a stunning 200% return over five years, cementing its status as one of the FTSE 100’s most dramatic recovery stories.
The journey has been anything but straightforward, with the pandemic delivering a near-fatal blow to the airline group and its shareholders in 2020.
IAG, which owns British Airways, Iberia, Aer Lingus and Vueling, suffered a €4.4bn operating loss that year as grounded flights drained cash reserves at an alarming rate.
To survive, the group was forced to raise €2.75bn from shareholders, a painful but ultimately decisive move that stabilised the business and set the stage for recovery.
As the dust settled, IAG shares looked extraordinarily cheap, with the price-to-earnings ratio falling to around three or four as markets priced in years of continued misery.
When travel demand rebounded sharply, the share price followed, though momentum has slowed more recently with gains of just 7.5% over the last twelve months.
The war in Iran has emerged as a key headwind, disrupting international routes and pushing jet fuel costs significantly higher across the industry.
IAG has cushioned some of the blow through hedging, with around 70% of its 2026 fuel needs covered and approximately 40% of 2027 already locked in, helping to limit near-term exposure.
The group expects to recover around 60% of higher fuel costs through fare increases, cost savings and other operational measures, though its total fuel bill could still reach approximately €8.6bn this year.
Rather than chasing passenger volume growth, IAG has opted to keep capacity expansion flat, a cautious strategy that reflects the uncertain global economic environment.
Consumer pressure remains a genuine concern, as holidays represent discretionary spending and a prolonged cost-of-living squeeze could see travellers pull back on leisure and business trips alike.
Airlines carry enormous fixed costs for aircraft, staff and airport infrastructure, meaning even modest shifts in demand or fuel pricing can have an outsized impact on profitability.
On the balance sheet, IAG has made meaningful progress, slashing net debt to €4.69bn while building a substantial €12.7bn cash and liquidity cushion to weather ongoing turbulence.
The stock currently trades at around seven times earnings, which looks inexpensive by most measures, though the structural volatility of the airline sector may justify a degree of valuation caution from investors.
The consensus twelve-month share price target from 24 analysts sits at 528p, implying potential upside of around 23% from the current price of 428p, according to available forecasts.
Deutsche Bank holds a more bullish stance, with a 645p target, and believes IAG can deliver strong 2026 operating profits while keeping margins within the group’s 12% to 15% medium-term guidance range.
Citigroup rates IAG a Buy with a 600p target, while RBC Capital Markets carries an Outperform rating and a 500p price target, reflecting broad but not unanimous optimism across major institutions.
Higher inflation, elevated fuel costs and squeezed consumer budgets could all act as near-term drags, even if the longer-term investment case remains broadly intact for patient shareholders.
For investors weighing up an entry point, IAG presents a genuinely interesting proposition, though the range of macro risks on the horizon suggests caution remains the sensible companion to any optimism.
