United Airlines Announces 5% Cut in Scheduled Flights Amid Surging Jet Fuel Costs

Chicago, March 21, 2026 — United Airlines has revealed plans to reduce its scheduled flights by approximately 5% in the near term, citing skyrocketing jet fuel prices triggered by ongoing conflict in the Middle East.

In a memo to employees shared on Friday, CEO Scott Kirby explained that the carrier is "tactically pruning" temporarily unprofitable routes to avoid "burning cash" on operations that can no longer absorb the dramatic increase in fuel expenses. Jet fuel prices have more than doubled in recent weeks due to geopolitical tensions, particularly the war involving Iran, which has disrupted global energy markets."If prices stayed at this level, it would mean an extra $11 billion in annual expense just for jet fuel," Kirby wrote. "For perspective, in United’s best year ever, we made less than $5B." He further warned that the airline is planning for oil prices to potentially reach as high as $175 per barrel and remain above $100 through the end of 2027.

The reductions, affecting about 5 percentage points of the airline's planned capacity for 2026, will primarily target the second and third quarters. This includes canceling roughly 3% of off-peak flying—such as red-eye flights, midweek services, and operations on lower-demand days like Tuesdays, Wednesdays, and Saturdays. United will also reduce about one percentage point of capacity at its major hub, Chicago O'Hare International Airport, once related FAA processes are complete. Additionally, the airline will maintain suspensions of service to Tel Aviv and Dubai, accounting for the remaining portion of the cuts.

Despite the adjustments, Kirby emphasized that the changes are short-term and that United intends to restore its full schedule by fall 2026. Long-term growth plans, including aircraft deliveries and capacity for 2027 and beyond, remain unchanged.The decision comes even as strong travel demand has enabled U.S. carriers, including United, to implement fare increases that partially offset rising costs. However, the unprecedented fuel spike has forced airlines across the industry to reevaluate marginal routes and prioritize profitability.

Travelers affected by the changes can expect potential schedule adjustments, with United advising customers to check flight statuses and rebook options through the airline's website or app. Industry observers note that similar capacity trims may follow from other carriers if fuel prices do not moderate soon.

United Airlines, one of the largest U.S. carriers, operates an extensive domestic and international network from hubs including Chicago, Denver, Houston, Los Angeles, Newark, San Francisco, and Washington Dulles. The latest move underscores the ongoing challenges faced by the aviation sector in navigating volatile energy markets amid persistent global uncertainties.
