Flight Delays and Cancellations

    The primary cause of the flight delays and cancellation is due to climate fluctuation and difficult terrain. The unusually dense fog, heavy rains, and high winds may cause aircraft delays or cancellations. The cold and rainy seasons are the most likely times for flight delays and cancellations. Another important problem is the lack of an instrument landing system at Tribhuvan International Airport, which causes domestic flights to be often delayed or canceled. rain in and around the airport, whether at TIA or other local airports. Under normal conditions, domestic flights in Nepal are infrequent from January through the end of February. There are monsoon flights available, however, they may be canceled due to excessive, there are no problems with flight times in Nepal, whether domestic or international.


    Months with the highest and lowest demand for flights

    There are extremely few occurrences of flight cancellations during the months of March-May and October-November since the weather is good and there is considerable visibility. It's crystal clear, dry, and steady. It is the finest season to visit Nepal for trekking and tours, mountain flights, and heli excursions.

    The other months of the year, notably (June-September) and (December-February), have a significant likelihood of flight cancellations. The monsoon season in Nepal begins in June and ends in September, therefore there are regular showers and low visibility for aircraft during this period. The other months, December-February, are brutal winters in Nepal, with dense fogs and mists and snowfalls on high slopes creating an impediment to planes. There are not always incidents of flight cancellation in the months of June-September and December-February, but it is advisable not to take the chance since human life is extremely important.

    So, if you are intending to visit Nepal, we recommend that you leave at least a couple of days extra in case your flight is canceled. Road transportation is an option in many areas in Nepal, however, if you are flying into Lukla (Tenzing-Hillary Airport), there is no motor road transit nearby owing to the terrain structure.



    Domestic flight cancellations are fairly regular in Nepal due to the country's geographical diversity and weather volatility. Because Nepal's Tribhuwan International Airport lacks the technology of an Instrumental Landing System, poor weather circumstances such as heavy rain, dense fog, high winds, and so on may cause aircraft delays and cancellations.

    Flight cancellations are quite unusual during the fall and spring seasons since the weather is usually clean and dry. However, we can never forecast the weather in the mountains. During the Monsoon and winter seasons, the weather is unpredictable, as heavy rain and dense fog reduce visibility, causing aircraft delays and cancellations.

    If our clients are interested in trekking in Nepal, we usually recommend that they have a few additional days in case of any flight problems. It is highly advisable to have additional days while traveling to the Everest Region and Jomsom Region, as the weather in these airports is rather unpredictable.


    (Note: Travel insurance is strongly advised. If your flight is canceled and you are unable to make your planned trip back to Kathmandu, Accessible Adventure may charter a helicopter for you. However, you should bear the expense, which can subsequently be reimbursed through your insurance provider.)
