Your Next Flight Just Got More Expensive — Here’s Exactly Why

A Middle East conflict launched in late February more than doubled jet fuel prices. Now American travelers are absorbing the bill — through higher fares, higher baggage fees, and fewer flight choices.

American air travelers are paying sharply more to fly, as a chain reaction set off by a U.S.-Israeli military campaign against Iran in late February has driven jet fuel prices to record highs and forced the country’s largest carriers to hike fares, cut routes, and raise checked-baggage fees for the first time in two years.

The U.S. Bureau of Labor Statistics reported that airline fares rose 14.9% over the 12 months ending in March 2026 — nearly twice the 3.3% headline inflation rate — as carriers passed on surging operating costs directly to passengers. The average domestic roundtrip ticket now costs $465.

The trigger was Operation Epic Fury, a coordinated U.S.-Israeli military campaign launched Feb. 28 targeting Iranian nuclear sites and military infrastructure. Iran responded by enacting a de facto closure of the Strait of Hormuz, the 21-mile-wide passage through which 20% of the world’s seaborne crude oil and nearly a quarter of its liquefied natural gas transit daily.

The International Energy Agency characterized the subsequent events as the “largest supply disruption in history,” noting that tanker traffic through the Strait collapsed 97% within three weeks. Approximately 20 million barrels of oil per day were sidelined, driving Brent crude from $78 per barrel in early February to peaks exceeding $130.

For airlines, the sharpest pain came not from crude oil itself but from refined jet fuel. According to data published by the BBC and verified through IATA’s Jet Fuel Price Monitor, European benchmark jet fuel surged from $831 per metric ton before the conflict to $1,838 per ton — an increase of more than 120%. In the United States, the national retail jet fuel average hit $4.88 per gallon by early April, up from $2.50 in late 2025.

The $11 Billion Problem

Delta Air Lines, United Airlines, and American Airlines — the so-called Big Three of U.S. aviation — collectively face an unbudgeted $11 billion increase in annual fuel expenses if prices hold at current levels.

In a staff memo, United CEO Scott Kirby noted that at current prices, United’s annual fuel bill would increase by $11 billion — more than double the profit the carrier earned in its best year. Delta CEO Ed Bastian told investors the fuel spike had already added $400 million to Delta’s operating expenses in March alone. “There’s a high sense of urgency to address higher fuel costs and reduce unprofitable flying,” he said.

Not all carriers are equally exposed. Delta owns the Trainer refinery in Pennsylvania, which is expected to provide a $300 million financial benefit in the second quarter of 2026 by capturing refining margins that are punishing its competitors. Southwest Airlines, by contrast, terminated its historically aggressive fuel-hedging program in 2025 in favor of a market-rate strategy, and saw its shares tumble 22% in March as it absorbed the full force of $4-plus-per-gallon jet fuel. American Airlines enters the second quarter with operating margins of just 3.1%; every one-cent rise in jet fuel adds approximately $50 million to its annual costs.

Closed Skies, Longer Routes

Beyond the cost of fuel itself, the conflict has physically obstructed the routes airlines fly. Aviation regulators, including the FAA and EASA, have issued stringent airspace prohibitions across 11 countries in the region. FAA NOTAM A1967/26 bans U.S. carriers from Iranian airspace indefinitely, while EASA’s Conflict Zone Information Bulletin warns against flying at any altitude over Bahrain, Iraq, Israel, Jordan, Kuwait, Lebanon, Qatar, the UAE, Oman, and Saudi Arabia.

The closure has forced 40,000 flight cancellations since hostilities began and pushed carriers onto longer bypass routes that increase sector distances by 5% to 10%. A Helsinki-to-Tokyo flight now requires a four-hour detour, adding $60,000 in operating costs on a single sector. Some carriers have been leaving seats empty on purpose to stay light enough for takeoff with the additional fuel load required, reducing available capacity and further driving up per-seat costs. Asia-Europe fares jumped 176% week-over-week in mid-March.

Fare Hikes and Higher Bag Fees

In response, U.S. carriers have cut flying and raised prices. United announced a 5% reduction in planned flights for the second and third quarters of 2026, targeting off-peak periods including Tuesday, Wednesday, and Saturday service and overnight red-eye flights. Delta pulled 3.5 percentage points from its original summer schedule growth.

Beginning in April, a cascade of baggage fee increases hit the market. Delta, United, and American now charge $45 to check a first bag in advance and $50 at the airport, with a third bag costing $200. Southwest ended its long-standing two-free-bags policy and now charges $45 per bag. JetBlue raised fees to between $39 and $49 depending on timing. Alaska Airlines charges $40 prepaid and $45 at the airport. Carriers benefit from the structure: baggage fees are not taxed at the same level as base fares, saving the industry an estimated $435 million in taxes annually.

Uncertain Recovery

A tenuous two-week ceasefire between the United States and Iran, mediated by Pakistan, was announced April 8, 2026, briefly sending airline stocks higher. But IATA Director General Willie Walsh warned that jet fuel supply will take months to recover even if the Strait of Hormuz remains open, given extensive damage to refining infrastructure across the region.

Qatar Airways has already ferried 22 jets — including its entire active fleet of Airbus A380s — to Teruel Airport in eastern Spain, citing “exceptional circumstances” stemming from restricted airspace at its Doha hub and the risk of damage from missile and drone activity. More than 25 wide-body aircraft arrived at the Aragonese facility between March 16 and March 26. United Airlines, meanwhile, accelerated the grounding and storage of its oldest Boeing 777-200s — including N777UA, the first 777 ever delivered, in 1995 — sending them to Victorville, Calif., pending availability of scarce Pratt & Whitney PW4000 engine components.

The March Consumer Price Index confirmed the broader consumer strain: prices rose 0.9% for the month, the largest single-month gain since 2022. Gasoline prices surged 21.2% in March — the largest monthly increase on record since 1967 — with the national average topping $4.00 per gallon for the first time since August 2022.
