Latvia's national airline, airBaltic, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code on Tuesday, citing the Iran war's severe disruption to global aviation operations.

The filing places the carrier's restructuring under U.S. courts and signals deepening financial strain across the international aviation sector. The Iran war has driven up fuel costs by an estimated 30 percent this quarter alone, forced airlines to reroute planes around closed air corridors, and spiked insurance premiums. Together, these pressures have squeezed airline balance sheets worldwide.

The move has triggered concern in Washington. House Transportation and Infrastructure Committee Chairman Sam Graves requested urgent briefings from aviation industry leaders and State Department officials. Treasury Department sources said officials are monitoring the situation for signs of broader economic contagion, though the Trump administration has not issued a formal statement.

Senator Chris Murphy, a frequent critic of U.S. military involvement in the Middle East, said the filing exemplifies the conflict's economic costs to American allies and businesses. While the war aims to secure U.S. interests, it has imposed real costs on global commerce.

AirBaltic's Chapter 11 filing offers a debt reorganization path unavailable under many foreign bankruptcy codes—a fact that may prompt other international carriers to follow suit. The U.S. Bankruptcy Court for the Southern District of New York will oversee the restructuring, with initial hearings set for late October. The Transportation Department plans to release a report next month on the global aviation sector's health.
