The head of the International Energy Agency (IEA, the Paris-based intergovernmental energy watchdog), Fatih Birol, has warned that European airlines may exhaust their jet fuel supplies within six weeks. Passengers should brace for reduced flight schedules and higher ticket prices, Birol cautioned, with carriers already cutting services ahead of the summer travel season. The warning underscores broader energy supply pressures in Europe, as officials also urge governments to maintain focus on restricting Russia's ability to profit from current energy market disruptions.
