What air travel changes mean for your next flight

The global aviation industry is facing its most severe crisis in decades due to the closure of the Strait of Hormuz, which has disrupted the supply of jet fuel to Europe and Asia. With 40% of Western Europe’s aviation fuel and 50% of Southeast Asia’s sourced from refineries near the strait, the ongoing conflict has triggered a cascade of flight cancellations, surcharges, and supply shortages. Airlines like Lufthansa, Air Canada, and WestJet are cutting capacity, raising prices, and warning of potential fuel exhaustion within weeks. Yet, experts warn that long-haul international flights—especially those critical to tourism and global trade—will be prioritized over short-haul regional routes. Passengers are advised to book flights early, avoid connecting flights on separate tickets, and carry extra buffer time. While the threat of a complete collapse in air travel is unlikely, travelers may face re-routing via rail or extended delays. The crisis has also reignited urgent conversations about sustainable aviation fuel and high-speed rail as long-term alternatives to fossil-fuel-dependent air travel. Despite the chaos, passengers retain legal protections: airlines must rebook travelers within 48 hours or offer full refunds if cancellations occur. However, insurance for trip interruptions—like prepaid accommodations—is increasingly uncertain. The situation underscores a deeper vulnerability in global supply chains and energy dependency.
