Distance is calculated between the two airports. Times are estimates from a stated formula, not a timetable — check the airline for actual times.
Rail on this sector is an overnight-plus journey, so flying is the sensible option unless you specifically want the train.
77 of 150 tracked offers are valid on international flights regardless of airline, across 45 providers and 16 booking platforms. A further 35 are tied to a specific airline — check that airline actually flies this sector before relying on one.
Flight time assumes an effective cruise of 780 km/h plus 35 minutes for taxi, climb and descent. Door-to-door adds 180 minutes for getting to the airport, security and exiting at the far end. Actual times vary by aircraft, routing and airport.
Travel needs
Request assistance with the airline after booking, ideally at least 48 hours before departure. Keep the request visible in your booking and arrive earlier at the airport.
Pre-book extra baggage, seat selection or priority services on the airline site before web check-in. Airport counters usually cost more.
Keep government ID, ticket, payment proof for offers, and destination documents ready. International trips may need visa, passport validity and return-ticket checks.
Route checklist
Before booking: compare fare, coupon eligibility, baggage allowance, refund rules and final payable amount.
After booking: add wheelchair assistance, seats, meals or extra baggage directly with the airline if needed.
At the airport: check terminal, lounge access, reporting time and document requirements for Delhi to Kathmandu.
International note: confirm visa rules, passport validity, return/onward ticket requirements and currency needs before paying.
Distance, timing, offers and booking questions for this route.
The two airports are about 815 km apart, so a nonstop flight is roughly 1h 38m. Allowing for getting to the airport, security and leaving at the far end, budget closer to 4h 38m door to door.
Flying is normally the practical choice. Rail on this sector is an overnight-plus journey, so flying is the sensible option unless you specifically want the train.
77 of the 150 offers we track are valid on international sectors on any airline, spread across 45 banks, cards, wallets and UPI apps. Another 35 are tied to a particular airline, so check that airline flies this sector first. Always compare the final payable amount, not the headline discount.
December–January: Dense winter fog over the Delhi plains commonly delays and occasionally diverts early-morning departures. A late-morning or afternoon departure is the safer choice in these weeks.
Check the airline or booking platform directly. Deal4Flight compares route information and payment offers, but does not publish live ticket prices.
Not always. Most promotions apply to the eligible ticket amount and may exclude baggage, seats, meals or insurance. Review the booking platform's terms before payment.
Only when the booking platform's terms explicitly allow stacking. Test eligible options separately and choose the lowest final payable price.
