Airlines Cut Flights and Hike Fares Amid Jet Fuel Crisis
- A global jet fuel crisis is forcing major airlines to slash flight capacities, raise ticket fares, and suspend routes as supply shortages and price spikes disrupt international aviation.
- United Airlines has implemented an immediate 5% reduction in planned capacity.
- Jet fuel prices have doubled since the start of the conflict in Iran, rising from approximately $2.17 to $4.56 per gallon by March 20, 2026.
A global jet fuel crisis is forcing major airlines to slash flight capacities, raise ticket fares, and suspend routes as supply shortages and price spikes disrupt international aviation. The crisis is primarily driven by a sharp drop in oil supply linked to the U.S.-Israel war on Iran, which has impacted energy shipments through the Strait of Hormuz.
United Airlines has implemented an immediate 5% reduction in planned capacity. According to CEO Scott Kirby, these cuts include approximately 3 percentage points from off-peak flying, 1 percentage point from reductions at Chicago O’Hare, and 1 percentage point from the suspension of service to Dubai and Tel Aviv. United expects to restore its full flight schedule in the fall of 2026.
Fuel Price Surges and Financial Impact
Jet fuel prices have doubled since the start of the conflict in Iran, rising from approximately $2.17 to $4.56 per gallon by March 20, 2026. United Airlines is currently modeling oil prices at $175 per barrel and anticipates that prices will remain above $100 through the end of 2027.
The price spike has resulted in significant financial losses for major U.S. Carriers. Delta Air Lines reported that the surge added as much as $400 million in costs during March 2026 alone. Similarly, American Airlines expects fuel costs to add approximately $400 million to its first-quarter expenses.
Global Network Disruptions
The instability is affecting carriers across multiple regions. Scandinavian Airlines (SAS) canceled approximately 1,000 flights in April 2026 due to rising costs. Air New Zealand has also joined the list of airlines cutting flights and hiking fares in response to the surge.
Other airlines identified as slashing flights amid the deepening crisis include AirAsia X, Air France-KLM, Cathay Pacific, and Thai Airways. These cuts are impacting travel plans across Europe and the Asia-Pacific region.
Ryanair CEO Michael O’Leary has warned that European airlines will begin cutting scheduled flights if the war in Iran does not end by the end of April 2026.
Supply Chain and Market Analysis
The shortage is rooted in a significant reduction of global oil supply. Bridget Payne, Head of Energy Forecasting at Oxford Economics, states that around 10 million barrels per day of oil supply has been removed from global markets.

Air travel is more discretionary than road freight or household energy use, and fuel surcharges pass through to ticket prices quickly.
Because aviation demand is highly sensitive to price increases, airlines are quickly passing these costs to passengers through higher ticket prices and surcharges. Industry leaders have warned that fuel supplies could be completely exhausted if the Strait of Hormuz remains blocked for more than 90 days.
Analysts suggest that if the current disruptions persist, the aviation sector could face even deeper cuts and widespread cancellations as the industry enters the peak summer travel season.
