Lufthansa announced it is preparing for refueling stopovers on long-haul routes as a jet fuel crisis looms due to Middle East supply disruptions.

Lufthansa CEO Carsten Spohr said on Wednesday the airline is preparing refueling stopovers due to potential jet fuel shortages caused by halted tanker traffic through the Strait of Hormuz, which provides about half of the EU's jet fuel imports, as Goldman Sachs research warns European commercial stocks could fall below 23 days of supply by late May or early June.
