United Airlines and other major US carriers cancelled numerous flights across the eastern Caribbean on January 4, 2026. The disruption follows sweeping airspace restrictions imposed by the US Federal Aviation Administration (FAA). The FAA issued the restrictions in response to US military action in Venezuela.
The cancellations affected travel during a busy holiday period. Key destinations impacted include Puerto Rico, Aruba, and the US Virgin Islands.
United Airlines is modifying its schedule immediately to account for the closures. The airline allows affected passengers to make changes without incurring fees. United, alongside other carriers, issued travel waivers and offers rebooking options or refunds to impacted customers.
