<h1>Carriers suspend flights to Kathmandu amid airport closure and protests, triggering passenger care, rebooking, refund obligations</h1> Several Indian carriers suspended and cancelled scheduled services to Kathmandu after Tribhuvan International Airport was temporarily closed amid large anti-government protests, with some flights diverted or returned during final approach due to smoke at the airport. Airlines announced multi-day cancellations, operational monitoring, coordination with local authorities, and one-time waivers on rescheduling and cancellation fees for affected bookings issued by specified dates. The sending state issued an advisory urging its citizens to defer travel until conditions stabilise. Operational disruptions raise carrier obligations under applicable aviation and consumer protection rules regarding passenger care, rebooking, refunds and timely communication.
