Only 3 U.S. Airlines Can Remain Profitable at Current Oil Prices

Crude Surge Exposes Airline Weakness

A sharp increase in oil prices, fueled by escalating conflict, is creating a challenging environment for U.S. airlines. Crude prices experienced a jump of over 9% recently, unsettling energy markets and raising concerns about potential disruptions around the Strait of Hormuz. This price spike is particularly concerning because many U.S. airlines have reduced or eliminated their fuel hedging programs in recent years, leaving them vulnerable to sudden cost increases.

Traditionally, airlines and oil producers use hedging strategies to mitigate the impact of oil price volatility. Airlines aim to secure predictable fuel costs, while producers seek to stabilize their revenue streams. Given that fuel can represent 15% or more of an airline's operating expenses, price swings can significantly impact profitability. Hedging, through futures, swaps, and options, allows carriers to lock in prices, shielding them from unexpected spikes. Airlines often hedge up to two-thirds of their anticipated fuel consumption approximately six months in advance, with European airlines generally adopting a more proactive hedging approach.

The Short List of Survivors

According to analysis, only Delta Air Lines (NYSE:DAL), United Airlines (NYSE:UAL), and Southwest Airlines (NYSE:LUV) are expected to remain profitable if fuel prices stay at or above $4 a gallon. While these three might stay afloat, other major airlines are likely to face significant losses. Delta and United's resilience is attributed to their higher operating margins. These airlines have historically benefited from strong premium travel demand, enabling them to maintain higher margins during periods of rising costs compared to their low-cost counterparts. They are also better positioned to pass on increased fuel costs to passengers through higher ticket prices and fuel surcharges.

Interestingly, Delta Air Lines owns the Monroe Energy refinery in Pennsylvania. While this doesn't directly protect the company from crude oil price surges, it offers a partial hedge against 'crack spreads', the difference between crude oil costs and finished jet fuel prices. Southwest Airlines, despite being a low-cost carrier, also benefits from downside protection. Southwest has a history of using aggressive fuel hedging strategies to manage fuel price volatility, although there are indications that the airline scaled back these activities in 2025 when oil prices were lower. Southwest's hedging program has provided considerable cost savings since its inception during the Great Recession. Furthermore, the carrier manages fuel expenses through a combination of a fuel-efficient fleet, operational efficiencies, and the integration of Sustainable Aviation Fuels (SAFs).

Southwest's all-Boeing 737 fleet reduces maintenance and training costs. The airline's use of newer, more fuel-efficient 737 MAX aircraft, which are about 16% more efficient than older models, also contributes to cost savings. The airline's focus on short-haul, point-to-point flights is generally more fuel-efficient than hub-and-spoke models. Southwest has also increased its use of SAFs, made from renewable waste, to reduce its reliance on conventional fuel.

Global Comparisons and Broader Market Trends

European and Asian airlines tend to hedge more aggressively than their U.S. counterparts. For example, Air France-KLM has hedged 87% of its fuel needs, and Ryanair has hedged 77%. Singapore Airlines, Cathay Pacific, and Virgin Australia also have strong hedging positions. However, these carriers still face high costs because their hedges are tied to Brent crude, which has not risen as quickly as the 'crack spread'.

Technical charts for airline indicators, such as the U.S. Global Jets ETF (JETS), suggest that the recent selloff is driven by more than just high fuel costs. Airline stocks have continued to decline even when crude oil prices have retreated, indicating a potential breakdown in long-term uptrends. The JETS ETF has fallen below its 200-day moving average and key uptrend lines that had been in place since early 2025.

Several factors contribute to this situation. The ongoing conflict in the Middle East has led to widespread flight cancellations and costly rerouting for international carriers. There are also growing concerns that sharp fare increases, implemented to offset fuel costs, will reduce consumer travel demand, particularly among price-sensitive leisure travelers. Airlines across Asia, Europe, and Oceania have begun raising ticket prices and implementing fuel surcharges following a significant increase in jet fuel costs, from approximately $85 to as high as $200 per barrel. In addition, major carriers like United Airlines face margin pressure from new labor contracts and general inflationary wage adjustments. Finally, cybersecurity has emerged as a critical operational risk for 2026, prompting the FAA to introduce new regulatory standards to combat AI-enabled attacks. United Airlines stock has fallen nearly 21% over the past month, while Delta is down around 17%, and American Airlines is down over 25%.

Portfolio Impact for Airline Investors

The surge in oil prices presents both risks and opportunities for investors in the airline sector. The near-term impact is clearly negative, particularly for airlines that have not adequately hedged their fuel costs. However, airlines with strong balance sheets, efficient operations, and effective hedging strategies, like Delta, United, and Southwest, may be able to weather the storm and potentially gain market share as weaker competitors struggle. Investors should closely monitor fuel prices, airline hedging strategies, and consumer travel demand. Key levels to watch include the $4 per gallon fuel price threshold and the performance of the JETS ETF. Related assets to watch include Brent Crude, WTI Crude, and the USD/CAD currency pair. A break above $4/gallon could trigger further downside in airline stocks, while a stabilization or decline in fuel prices could provide some relief. The resilience of premium travel demand will also be a critical factor in determining the profitability of major carriers. Investors should also be aware of the potential for further geopolitical instability, which could exacerbate the situation.
