Jet fuel prices double after Hormuz closure, tripling Asia-Pacific fares and grounding United flights

Jet fuel prices have nearly doubled in three weeks following Iran’s closure of the Strait of Hormuz on March 4, 2026, pushing US spot prices to a three-year high near $4 per gallon. Airlines including United have already cut capacity on Asia-Pacific routes and halted Middle East services, with transcontinental US fares surging from $167 to $414 and international routes seeing increases of over 300%.

The Energy Information Administration now projects 2026 jet fuel averaging $2.67 per gallon — 37% above prior forecasts — with fuel accounting for over 40% of airline operating costs. Travelers holding bookings on trans-Pacific and Asia-Pacific routes face potential cancellations or fare increases through Q3 2026, with waivers expiring as early as March 30 for some carriers.

The Iran war’s stranglehold on Gulf oil exports is forcing airlines to ground flights and slash capacity on routes connecting North America, Europe, and Australasia to Asia-Pacific destinations. United Airlines announced cuts to off-peak redeyes and Tuesday/Wednesday/Saturday flights for Q2-Q3 2026, while suspending service to Dubai and Tel Aviv entirely.

The immediate trigger: Iran’s blockade of the Strait of Hormuz stranded oil and LNG shipments, causing Brent crude to surge past $120 per barrel and QatarEnergy to declare force majeure. Kerosene-based jet fuel prices doubled as refineries lost access to Iranian crude feedstock.

Travelers departing from Los Angeles, San Francisco, London, Frankfurt, Sydney, and Melbourne to Tokyo, Seoul, Singapore, and Hong Kong face the highest exposure. Middle East hub connections — the backbone of many Europe-Asia itineraries — are collapsing as Gulf carriers absorb fuel cost shocks that now represent nearly half of operating expenses.

How the fuel crisis is reshaping Asia-Pacific flight networks

US jet fuel spot prices hit $4 per gallon last week, with the Energy Information Administration revising its 2026 average forecast to $2.67 per gallon — a 37% jump from earlier projections and 7% above 2025 levels. The EIA’s updated outlook reflects sustained supply disruption as the Strait of Hormuz remains closed with no diplomatic breakthrough in sight.

United’s capacity cuts target feeder routes that connect US domestic passengers to Asia-Pacific gateways — the off-peak flights that fill widebody aircraft departing LAX and SFO for Tokyo Narita and Seoul Incheon. Transcontinental US fares rose from $167 to $414 in three weeks, while JetBlue’s New York–Santo Domingo route jumped from $166 to $566, over four times the year-ago price.

Australia has reported petrol shortages stemming from the Hormuz blockade, signaling parallel jet fuel supply constraints for Qantas and Scoot on Sydney–Melbourne–Singapore routes. Refineries across Asia lack Iranian crude for kerosene production, raising the specter of groundings on intra-Asia routes like Singapore–Hong Kong if prices hold above $100 per barrel through April.

Why this fuel shock hits harder than past crises

The 1979 Iranian Revolution and 1980 Iran–Iraq War offer the closest historical parallel — oil prices doubled to $39 per barrel (equivalent to over $150 today), triggering global jet fuel spikes that grounded flights and raised fares 50–100% until mid-1981 stabilization via Saudi spare capacity. Airlines cut 10–20% capacity during that period, with recovery taking 18 months amid recession impacts.

The current crisis compounds differently. Fuel now accounts for over 40% of airline operating costs, up from roughly 30% in the early 1980s, meaning carriers have less margin to absorb price shocks without immediate capacity cuts or fare increases. The Strait of Hormuz closure on March 4 stranded not just oil but also LNG exports, creating a dual energy crisis that affects both jet fuel production and airport ground operations.

QatarEnergy’s force majeure declaration signals that even Gulf carriers with state backing cannot shield themselves from supply chain collapse. The Fortune analysis notes that airlines face a binary choice: ground aircraft or pass costs to passengers at levels that destroy demand.

What to do if you have an Asia-Pacific booking

Airlines are issuing waivers on routes affected by fuel cost surges and capacity cuts, but deadlines vary by carrier and booking class.

• Existing United bookings to Asia via Middle East hubs: Check united.com/manage or call 1-800-UNITED-1 for free rebooking options announced March 24. Act by March 30 to avoid change fees as capacity cuts take effect in Q2.
• Planning new trips from North America or Europe to Asia-Pacific: Avoid March–April departures. Use Google Flights to compare direct LAX–Tokyo Narita on ANA or SFO–Seoul Incheon on Korean Air against hub connections — monitor for fuel surcharges that may not appear in initial search results.
• Currently in Asia or in transit: Contact your airline immediately if you receive schedule change notifications. Carriers are required to rebook you on the next available flight at no cost, but seat availability is collapsing as capacity shrinks. Document all communications for potential claims.
• Australasia travelers: Review qantas.com/travel-info for fuel surcharge updates on Sydney–Singapore and Melbourne–Hong Kong routes. Qantas has historically added surcharges within 7–10 days of crude oil spikes above $100 per barrel.

Watch: EIA’s April Short-Term Energy Outlook will reveal whether jet fuel prices are expected to stabilize below $2.67 per gallon or climb further — that forecast will determine whether airlines restore capacity in Q3 or extend groundings into Q4.
