UK airlines given green light to cancel or consolidate flights to conserve jet fuel

UK airlines have been granted permission to cancel or consolidate flights to conserve jet fuel amidst ongoing disruptions to supplies caused by the war in the Middle East. This measure aims to prevent summer travel chaos by allowing carriers to proactively adjust schedules. Airlines can now give back a limited number of takeoff and landing slots without jeopardizing their rights for future seasons, a change from previous regulations that penalized cancellations. Flights will need to be cancelled at least two weeks in advance, enabling passengers to be rebooked on alternative services with more notice. This decision, announced by the government, follows discussions with major airports and airlines.

Spirit Airlines has ceased all operations and cancelled all flights, initiating an "orderly wind-down" of its business. This decision comes after a potential White House bailout failed to materialize. The budget carrier's collapse is attributed to a significant increase in jet fuel prices, which have doubled due to the ongoing Iran war. Spirit had been attempting to emerge from bankruptcy, but the rising fuel costs derailed its financial recovery plans. The shutdown will result in thousands of job losses and impacts a substantial number of scheduled domestic flights.

California's jet fuel supply has fallen to a three-year low, with stocks at just over 2.6 million barrels as of April 17th. This shortage is attributed to global oil market disruptions stemming from Middle East turmoil, particularly impacting California's significant reliance on foreign oil imports. The conflict has led to a surge in jet fuel prices nationwide, with averages climbing significantly since early 2026. Airlines are responding by increasing baggage fees and implementing fuel surcharges. While a complete inability to fuel planes is not anticipated, travel experts foresee potential flight cancellations, especially on less profitable routes, due to the ongoing supply pressures.

In April 2026, Europe faces a critical jet fuel shortage threatening to ground flights at the start of the summer travel season. The shortage stems from disruptions at the Strait of Hormuz, a vital oil and LNG passageway, due to the ongoing US-Iran conflict. This has caused a collapse in supplies and a spike in energy prices. The head of the IEA warns that Europe has approximately six weeks of jet fuel remaining, potentially leading to flight cancellations if oil supplies remain halted, despite a recent truce. Europe is particularly vulnerable, as it imports 75% of its jet fuel from the Middle East. The UK is leading a coalition to reopen the strait.

A looming jet fuel shortage in Europe and Asia, triggered by the Iran war and the closure of the Strait of Hormuz, threatens to disrupt global air travel. According to the International Energy Agency (IEA), Europe has approximately six weeks of jet fuel reserves remaining. The Strait of Hormuz accounts for 40% of Europe's jet fuel imports, which have ceased since the war began. Jet fuel, a kerosene-based product, constitutes about 30% of airlines' expenses, and prices have doubled since the conflict started. The potential shortages could lead to higher airfares and flight cancellations as airlines pass increased costs onto consumers through baggage fees, ticket prices, and fuel surcharges.

The head of the International Energy Agency (IEA) warned that Europe has approximately six weeks of jet fuel remaining due to blocked oil supplies stemming from the Iran war. This shortage could lead to flight cancellations soon. The IEA director described the situation as the "largest energy crisis" ever faced, with global repercussions including higher prices for petrol, gas, and electricity. The crisis, caused by disruptions in the Strait of Hormuz, will disproportionately affect developing countries in Asia, Africa, and Latin America, while countries like Japan, South Korea, India, China, Pakistan and Bangladesh are on the front line of the energy crisis. The IEA anticipates significant implications for the global economy, including reduced economic growth and increased inflation.
