Your guide to booking Kathmandu to New Delhi flights

Get tips on when to book, when to fly and what to know before your trip.
  • If your dates can be flexible, aim for a Tuesday departure instead of Saturday. On this route, Tuesday flights average $169 - about $20 less than Saturday (11% savings) based on the last 12 months.
  • For the best chance at a low fare, aim to book around 23 weeks before you fly. On this route, that window historically saves about 25% versus last-minute pricing (KAYAK booking data, last 12 months).
  • If you can choose when to travel, plan your Kathmandu to New Delhi trip for January. Fares historically average $141 round-trip in that month - typically $98 less than the most expensive month, which is April (based on the last 12 months).
  • If arriving on time is high on your priority list, IndiGo is the strongest pick on this route. 83% of IndiGo flights from Kathmandu to New Delhi arrived on time in the past 3 months, slightly above the route's average on-time arrival rate of 74%. When flights on this route do arrive late, the average delay is 2 hours 5 minutes, so choosing a carrier with strong on-time performance can make a difference on tight schedules.
  • If you're arriving late at night and need somewhere to stay, check out these hotels close to New Delhi Indira Gandhi Intl Airport.
    - Radisson Blu Plaza Delhi
    - Pride Plaza Hotel, Aerocity New Delhi
    - ibis New Delhi Aerocity
  • When flying out of Tribhuvan International Airport (KTM), you need to ensure that you arrive at the airport at least 2h before the scheduled departure time. This is because the airport experiences long queues so you will need enough time to go through the lines.
  • If you’re looking for specific in-flight services such as in-flight snacks or entertainment, please confirm their availability during the booking. This is because different flights usually have different services on offer even when they are serviced by the same airline.
  • If you plan on booking connecting flights, please avoid the ones with a self-transfer label and instead go for those with automatic transfers. Self-transfer flights will require you to check in every flight and ensure that your luggage is checked in as well which can sometimes be hectic, especially in cases where one flight has been delayed.
  • Indira Gandhi International Airport (DEL) has childcare lounges at every terminal. This is ideal for anyone traveling with an infant who needs a private space to change diapers and nurse their child.
  • If you need a place to exchange currency at DEL Airport, Central Bank of India, Centrum and Thomas Cook provide foreign exchange services at the airport. You can find them in the Domestic and International Arrivals sections in Terminal 3 as well as the International Departures in Terminal 1.
