Key Takeaways
- U.S. airlines spent over $5 billion on jet fuel in March 2026, a 56% increase from February.
- Rising fuel costs driven by the U.S.-Israeli strikes on Iran forced airlines to raise fares and reduce capacity.
- European carriers face billions in losses, passing costs onto customers amid ongoing geopolitical tensions.
U.S. airlines spent just over $5 billion on jet fuel in March 2026, reflecting a 56% jump from February’s expenses, according to the U.S. Transportation Department. The surge stems from a 31% rise in fuel prices per gallon to $3.13, coupled with a 20% increase in fuel consumption. These developments follow heightened geopolitical turmoil after the U.S. and Israel struck Iran, disrupting traffic through the Strait of Hormuz and sparking the aviation sector’s most severe crisis since the pandemic.
Fuel Price Spike Disrupts U.S. and Global Aviation
Jet fuel costs have skyrocketed amid the Iran conflict, with crude oil prices climbing from $85-$90 to between $150 and $200 per barrel. Fuel typically comprises about 25% of airlines’ operating costs, and this escalation has strained carrier finances. American Airlines Group (BMV:AAL) lowered its 2026 profit outlook, warning of losses at the bottom of its guidance. The company has already increased checked baggage fees—adding $10 to the first and second bags and $150 to the third on domestic and short-haul routes—and reduced some economy class amenities.
Delta Air Lines Inc (NYSE:DAL) announced plans to reduce capacity by about 3.5 percentage points below earlier forecasts while raising checked bag fees by $10 for the first two bags and $50 for the third. Delta has canceled all planned capacity growth for the current quarter and projects profits below Wall Street expectations. These moves demonstrate how surging fuel costs are forcing airlines to adapt operations and revenues aggressively.
European Carriers Brace for Fuel-Related Losses
Deutsche Lufthansa AG (ETR:LHAG) expects a significant 1.7 billion euro hit from soaring jet fuel prices in 2026. Its subsidiary, ITA Airways, plans to increase ticket prices by 5% to 10% this year to offset costs. Additionally, the Lufthansa group introduced a new low-cost “Economy Basic” fare for short- and medium-haul flights, restricting free carry-on baggage to just one laptop bag or small backpack. These measures indicate the broader impact of fuel price volatility on airline pricing structures and customer offerings across markets.

Fuel remains a critical factor shaping airline profitability and operational strategies in 2026.
Fuel: Industry Impact and Market Outlook
The $5 billion jet fuel expenditure in March exemplifies the sharp financial toll exacted by the Iran conflict on U.S. airlines. With fuel prices and consumption both rising steeply, airlines like American Airlines and Delta face challenging year-ahead forecasts. European companies such as Lufthansa also grapple with substantial increased costs and have begun passing these onto ticket buyers while adjusting service offerings.
Investors and market watchers should monitor the evolving geopolitical situation closely, as fuel price volatility directly influences airline earnings and sector valuations. High fuel expenses will likely continue to reshape pricing policies and network capacity decisions, underscoring fuel’s pivotal role in aviation market dynamics throughout 2026.
