Helicopter flights operate year-round, but the best seasons are spring (March–May) and autumn (September–November). During these periods, weather conditions are generally stable, skies are clearer, and mountain views are spectacular. These seasons also coincide with peak trekking and climbing activity, making helicopter services highly in demand. Winter flights are possible but may face cold temperatures and occasional snow. Monsoon season (June–August) brings clouds, rain, and limited visibility, which can cause delays or cancellations. Early morning flights are usually preferred because winds are calmer and visibility is better. Booking in advance during peak seasons is strongly recommended to secure availability and preferred departure times.
