Due to its challenging geographical terrain and diverse climate conditions, domestic flights in Nepal are susceptible to delays and cancellations. The Tribhuwan International Airport in Nepal lacks the technology of an Instrumental Landing System, making it particularly sensitive to adverse weather elements such as heavy rain, thick fog, strong winds, etc., which can lead to flight disruptions. The challenging geography of Nepal further emphasizes the need for caution, and it is considered unsafe to take flights during unfavorable weather conditions.

As indicated on our website under the best trekking season section, the autumn season (November-September) is the most favorable for trekking, characterized by dry, clear, and stable weather. During this time, flight delays and cancellations are rare. However, for other seasons, weather conditions cannot be guaranteed. The monsoon season (June-August) is especially prone to flight disruptions due to strong winds, heavy rain, and unpredictable clouds, making visibility challenging. Similarly, in the winter season, flights may be canceled due to thick fog.

Therefore, if you are traveling to Nepal, it is advisable to allocate an extra day or two in case your flight gets canceled, ensuring that you have a buffer in your schedule. In some cases, road transportation can be an alternative. However, for flights to Lukla, adjusting your entire schedule may be necessary if you are short on time, as there are limited alternatives due to its challenging location. It’s important for travelers to plan accordingly and be flexible, considering the unpredictable nature of domestic flights in Nepal.
