Global airlines have suffered their worst financial shock since the COVID‑19 pandemic as the ongoing war involving US Israel and Iran has disrupted industry operations, wiping more than $50 billion off the market value of the world’s largest carriers amid rising fears of fuel shortages.The conflict, now entering its fourth week, has grounded flights, disrupted key Gulf hub airports and driven jet fuel prices sharply higher, compounding pressure on an industry that was rebounding strongly following pandemic‑related losses.According to Financial Times calculations, the 20 largest publicly listed airlines have collectively lost about $53 billion in market capitalisation since the war began. In response, airline executives have warned of a potential rise in ticket prices as carriers seek to protect shrinking profit margins.Jet fuel, which accounts for roughly a third of operating costs for airlines, has doubled in price since the United States and Israel launched attacks on Iran at the end of February. Many carriers had hedged against fuel price swings, but the rapid rise is expected to force airlines to pass on costs to passengers.“Fuel spiked quite heavily after the Ukraine invasion in 2022 as well, but this has gone further north,” easyJet chief executive Kenton Jarvis told FT, describing the current crisis as the most significant upheaval since the pandemic closed global skies in 2020.Executives also point to broader structural challenges, including the risk that sustained high fares may dampen demand. Carsten Spohr, CEO of Lufthansa, said higher ticket prices were unavoidable but expressed concern that they could weaken long‑term demand. “Our average profit is about €10 per passenger, there’s no way you can absorb the additional cost,” he said.In addition to passenger traffic pressures, airlines are preparing contingency plans for possible jet fuel shortages. Air France‑KLM CEO Ben Smith said the carrier is drawing up measures to cope with potential supply squeezes, including scaling back services on some Asian routes.The crisis has hit Middle Eastern carriers particularly hard. Carriers such as Emirates, Etihad and Qatar Airways have had to sharply reduce schedules due to airspace closures and a collapse in regional tourism, industry officials say. Despite the severity of the current disruption, Willie Walsh, head of the International Air Transport Association (IATA), noted that it still falls short of the pandemic’s impact but is reminiscent of the downturn in transatlantic demand after the 9/11 attacks, according to FT.

The conflict’s ripple effects are also visible in cargo operations, as freight traffic shifts from disrupted shipping routes to air cargo, straining airport facilities. At Geneva airport, for example, freight re‑routing has led to overflow onto services bound for Paris.Industry observers remain hopeful that airline valuations and demand will rebound once the conflict abates. “The share price has moved against all airlines since the start of the conflict,” Jarvis said, adding that short sellers would likely close positions quickly if a ceasefire is announced.
