<h1>Volcanic ash forces major India flight cancellations as aviation regulator orders safer routes, extra fuel and planning changes</h1> Volcanic ash plumes from the Hayli Gubbi eruption in Ethiopia disrupted international air operations at India's largest airport, causing multiple flight cancellations and delays. At least seven international flights were cancelled and twelve delayed, while one major Indian carrier cancelled thirteen flights since Monday. Authorities reported ash clouds drifting towards western India, increasing operational risk. In response, the aviation regulator issued directives requiring all airlines to avoid designated volcanic ash-affected areas and flight levels, and to revise flight planning, routing, and fuel calculations in line with current advisories, emphasizing safety and regulatory compliance in air navigation.
