Airline stocks moved sharply lower Monday as oil prices surged above $100 per barrel, raising concerns about rising jet fuel costs and pressure on industry profitability.
Shares of major U.S. carriers fell after crude oil briefly climbed above $110 per barrel, the highest level since 2022. The move followed escalating geopolitical tensions in the Middle East that disrupted shipping traffic through the Strait of Hormuz, one of the world’s most critical oil transit routes.
Delta Air Lines, American Airlines, and United Airlines all declined in early trading before trimming some losses. Domestic-focused carriers including Southwest Airlines, JetBlue Airways, and Alaska Air Group also traded lower as investors weighed the financial impact of higher fuel prices.
Fuel represents one of the largest operating expenses for airlines, typically accounting for roughly one-fifth to one-quarter of total costs. When oil prices climb quickly, airlines often face immediate margin pressure, particularly if ticket prices cannot be adjusted quickly enough to offset the increase.
Jet fuel prices have climbed significantly in recent weeks, rising by as much as $1.75 per gallon. At those levels, the largest U.S. airlines could see quarterly fuel expenses increase by roughly $1.5 billion each if elevated prices persist. Across the three largest carriers, the additional costs could approach $5 billion.
Higher fuel costs often translate into higher ticket prices as airlines attempt to protect margins. Carriers may adjust fares, reduce promotional pricing, or alter route capacity in response to sustained increases in fuel expenses.
The current price spike also highlights the industry’s increased exposure to energy market volatility. Many airlines previously used fuel hedging strategies to limit the impact of oil price swings. Over the past decade, however, most carriers have moved away from large-scale hedging programs after experiencing losses during periods of falling oil prices. Southwest Airlines, long known for its fuel hedging approach, ended its program in 2025.
In addition to rising energy costs, airlines are facing operational disruptions tied to the conflict. Thousands of flights have been grounded globally as airlines reroute aircraft away from affected airspace, leaving travelers stranded and adding complexity to airline scheduling.
European airline stocks also declined amid the developments. Lufthansa shares dropped roughly 5%, while International Consolidated Airlines Group, the parent company of British Airways and Aer Lingus, fell about 3%. Air France-KLM also moved lower during the session.
The latest selloff adds to a difficult year for airline equities. Shares of Delta, American, and United are down roughly 20% to 30% year to date. Domestic carriers such as JetBlue, Southwest, and Alaska Air have also experienced steep declines in recent weeks.
For investors, the move underscores how closely airline performance remains tied to global energy markets. Even with steady travel demand, sudden spikes in oil prices can quickly reshape the profitability outlook for carriers.
If crude oil remains elevated, airlines may continue adjusting pricing strategies and operating plans as they navigate the industry’s most volatile cost variable.
