London Heathrow and Gatwick airports cancelled multiple flights on November 14 and 15, 2026, as a US Federal Aviation Administration (FAA) nationwide air traffic control ground stop disrupted operations.
These cancellations directly impacted transatlantic flights, forcing airlines to delay or cancel services at these key UK airports.
Passengers traveling from Heathrow and Gatwick faced widespread disruptions on flights to the US and other destinations connected with US airspace.
The shutdown caused cascading effects as US air traffic restrictions rippled into Europe, prolonging operational challenges even after the grounding ended.
