Jet Fuel Crisis Threatens Higher Fares and Summer Flight Cancellations

The Airports Council International warned that surging jet fuel costs will inevitably lead to higher ticket prices and the cancellation of unprofitable flight routes. According to reports, Lufthansa Group expects an additional $2 billion in costs this year due to kerosene supply shortages caused by the Strait of Hormuz closure. Furthermore, the IEA warned in mid-April that Europe might have only six weeks of jet fuel supply remaining.

These pressures emerge amid widespread energy market disruptions, as the halt of Middle Eastern exports has forced airlines to seek expensive alternatives, per market data. Compared to the previous quarter, earnings reports from major carriers like Delta Air Lines show increasing pressure on operating margins, with energy experts citing reduced Asian refinery output as a key factor exacerbating the global shortage.

Investors should monitor the impact of these costs on inflation levels, especially following Mexico's CPI data release of 4.45% on May 7, 2026. Markets are also awaiting ECB President Lagarde's speech on May 8, 2026, for potential monetary policy responses to transport-driven inflation. Given the current supply constraints, the aviation sector's outlook remains tied to the duration of critical waterway closures.
