US airline stocks have officially erased their pandemic-era losses, a recovery that took six years to achieve. This significant milestone is largely attributed to a decrease in oil prices, which has alleviated the financial pressure on carriers. A key factor in this decline is the progress on a peace deal between the US and Iran, leading to hopes of increased crude supplies and lower fuel costs.
The S&P 500 Passenger Airlines index jumped as much as 5% to an all-time high and has risen nearly 13% since June 12, following the announcement of the US-Iran peace agreement. In contrast, the broader S&P 500 benchmark has seen a 0.5% drop during the same period. Brent crude futures notably fell below the $74-a-barrel mark, reaching levels not seen since before the Iran war, due to signs of increased oil tanker movement through the Strait of Hormuz. Jet fuel prices, which had soared past $170 a barrel during the conflict, have now retreated to an average of $119.17 by June 19, down from an average of $85 to $90 before the war in February.
Analysts predict that these lower fuel costs could save airlines billions of dollars, potentially allowing for outperformance of Wall Street earnings expectations in the third quarter, especially for carriers with smaller fleets and fewer premium seats. Notable airline stock increases include American Airlines surging about 7%, Alaska Air and United up about 6% each, JetBlue rising 4.5%, Delta up 3.7%, and Frontier and Southwest gaining 3% each. Online travel firms like Booking Holdings and Expedia also saw significant increases, between 7% and 10%.
Despite the positive outlook for airline profitability and investor interest, an immediate decline in airfares for passengers is not expected. This is primarily due to tight capacity within the airline industry. US summer airfares remain about 15% higher than in 2025, even as the historic jet fuel crisis that led to the collapse of Spirit Airlines and warnings of fuel shortages in Europe is now fading. The softening oil prices are part of a broader story facilitated by the ending of the conflict with Iran, which is expected to prompt a resumption of industrial ventures and a corresponding increase in profitable business and holiday travel.
