United Airlines Cuts Flights as Iran War Fuels Jet Fuel Price Surge

United Airlines is proactively reducing its flight schedule by 5% over the next two quarters, a move directly linked to escalating jet fuel costs driven by ongoing geopolitical instability in the Middle East. The airline anticipates oil prices could surge to $175 a barrel and remain above $100 through the end of 2027, a scenario that would add approximately $11 billion to its annual fuel bill – more than double its most profitable year.

The decision, announced in a staff memo from CEO Scott Kirby on March 21, 2026, reflects a broader trend within the airline industry of adapting to a volatile energy market. While strong travel demand has allowed U.S. Carriers to increase fares, United is prioritizing profitability over maintaining capacity in the face of potentially crippling fuel expenses. This strategy diverges from some international carriers who utilize fuel hedging, a practice largely absent among U.S. Airlines.

Cutting Marginal Flying

United isn’t implementing blanket cuts. Instead, the airline is targeting less profitable routes and flight times. According to the memo, approximately three percentage points of the reduction will come from off-peak flying, specifically red-eye flights and midweek services. An additional one percentage point of capacity will be removed from Chicago O’Hare International Airport. Service to Tel Aviv and Dubai will remain suspended, contributing to the overall 5% reduction in planned capacity for the year.

Kirby indicated the airline expects to restore the full schedule in the fall, suggesting this is a temporary adjustment rather than a long-term restructuring. This approach mirrors comments made earlier in the week, where Kirby stated a preference for leaving some demand unmet rather than operating routes that are projected to lose money given current fuel prices.

Fares Help Soften the Hit

Despite the challenging environment, United and other major U.S. Airlines are benefiting from robust travel demand. This allows them to partially offset rising fuel costs through fare increases. Delta Air Lines, for example, recently raised its first-quarter revenue forecast and has indicated flexibility to further reduce capacity if fuel prices remain high. The capacity reductions, like those announced by United, are expected to further bolster the industry’s ability to maintain pricing power.

The current situation is particularly challenging for low-cost carriers, who are already facing pressure from rising labor costs. Soaring fuel prices exacerbate these existing financial strains. However, airline executives remain optimistic, citing strong booking trends and the ability to pass on increased costs to consumers. United has reported that the first ten weeks of the year represent the strongest booking period in its history, a sentiment echoed by other major carriers.

Long-Term Growth Intact

Despite the short-term adjustments, United remains committed to its long-term growth strategy. The airline plans to continue taking delivery of approximately 120 new aircraft this year, including 20 Boeing 787s, with an additional 130 aircraft scheduled for delivery by April 2028. Kirby emphasized that United will not resort to measures like furloughs or delaying future investments, signaling confidence in the airline’s future prospects.

The situation highlights the delicate balance airlines face in navigating a complex global landscape. While demand remains strong, external factors like geopolitical events and energy market volatility can quickly impact profitability. The coming months will be crucial in determining whether airlines can successfully manage these challenges and maintain financial stability. Industry observers will be closely watching fuel price fluctuations and the effectiveness of fare increases as key indicators of future performance.
