US airfares have surged significantly, with domestic prices climbing 26.5% compared to a year earlier and global fares rising 25-30% relative to 2025. The spike stems primarily from elevated jet fuel costs, which have increased substantially due to the ongoing conflict and reduced global refining capacity. Jet fuel was trading around $149 per barrel in early August, a 65% increase from the start of this year, while crude oil prices have risen approximately 30% since January.
The disparity between jet fuel and crude oil price increases reflects structural constraints in the refining sector. Jet fuel represents only about 10% of refined oil output, making it more vulnerable to supply disruptions. Multiple refinery closures have exacerbated shortages, though a new west African facility and operational adjustments by refineries producing 12-14% jet fuel have provided some relief. For airlines, fuel costs constitute their largest operating expense, typically representing 30-35% of total costs.
Additional factors beyond fuel prices compound upward pressure on fares. Aircraft delivery delays from Boeing and Airbus, combined with ongoing Federal Aviation Administration staffing challenges that reduce flight capacity at major airports, limit the supply of available seats. Airlines have capitalized on these conditions to pass increased costs directly to consumers, with strong travel demand providing little incentive for price reductions. The industry faces structural headwinds that may persist regardless of geopolitical developments, as analysts note that even a ceasefire could require a year or longer for fuel prices to normalize.
The competitive landscape has further tightened following Spirit Airlines’ closure earlier in the year, reducing low-cost competition and potentially supporting higher fares across the industry. Most airlines operate on tight margins, with legacy carriers like American, United, and Delta using higher ticket prices to offset fuel volatility. Travel analysts recommend booking flights promptly rather than waiting for price declines, noting that fall and winter holiday fares are already showing substantial increases compared to the previous year.
