Everything you need to know for your flight from Siddharthanagar to Kathmandu

Which departure days are usually cheaper?

If you have flexibility with your travel dates, Tuesday and Wednesday departures are consistently your best bet for finding the lowest airfares. Across global flight routes, flying midweek can easily save you 10% to 20% compared to weekend departures, mainly because you avoid both Monday business trips and Friday weekend getaways. On the flip side, Fridays and Sundays tend to be the most expensive days of the week as leisure travelers head out and return. Another insider tip: opting for early morning flights (before 7:00 AM) or overnight red-eyes often unlocks additional savings while helping you breeze through airport security lines.

How far in advance do fares usually reach their lowest point?

There is no fixed booking window that guarantees the lowest fare for Nepal to Nepal (NP-NP). Once your plans are clearer, compare prices for your intended dates and nearby alternatives, using the same cabin, baggage and change conditions. Choose a fare that fits your budget and flexibility; waiting can result in either lower prices or fewer suitable options.
