Fort Worth-based American Airlines has temporarily suspended select routes for August and September, citing elevated jet fuel costs driven by the ongoing conflict with Iran that has disrupted global energy supplies.

The airline said affected travelers would be offered alternative arrangements or refunds, and emphasized that the suspensions are temporary rather than permanent route eliminations. American maintained that it remains proud to offer an industry-leading network with more flights than any other U.S. carrier.

Six routes are reportedly affected, largely originating from Los Angeles, among other North American destinations. None of the suspended routes arrive or depart Dallas-Fort Worth International Airport, American’s primary hub.

The suspensions reflect broader industry pressures as jet fuel costs soar amid the Strait of Hormuz crisis. A barrel of jet fuel averaged nearly $142 last week, according to the International Air Transport Association, down from an April peak but still far higher than the $99 per barrel price before the U.S. and Israel launched military operations against Iran in late February.

Airlines worldwide have canceled flights, trimmed schedules, and hiked fees in response to rising fuel costs, which can account for approximately 30% of total operating expenses. The summer suspensions could compound challenges for travelers already facing fewer flight options and higher ticket prices.

Most traffic through the Strait of Hormuz, a critical waterway for global oil flows, has remained at an effective halt for over three months. Prices have moderated somewhat as markets anticipate an eventual reopening, but the U.S. and Iran have yet to reach a concrete agreement to restore normal shipping traffic.

American Airlines’ decision highlights the cascading effects of the geopolitical conflict on the aviation industry. Consumer impacts extend beyond air travel, with gasoline, food, and everyday essentials also affected by supply disruptions originating from the conflict.

The airline said it continues to monitor fuel costs and market conditions, with potential for further adjustments depending on how the geopolitical situation evolves through the remainder of the summer travel season.
