Looking for cheap flights from Lucknow to Kathmandu? FlightGPT compares live LKO to KTM fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Lucknow to Kathmandu non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Lucknow-Kathmandu fare is one search away.
Buddha Air — Nepal's largest private carrier — operates the LKO→KTM non-stop on ATR 72 turboprops when the route is active. However, the direct service is seasonal and schedules can change, particularly during the monsoon (June–August) when Tribhuvan Airport in Kathmandu operates under instrument-weather restrictions. IndiGo and Air India offer 1-stop connections via Delhi year-round, which are more reliable in terms of frequency and seat availability. The LKO→DEL domestic hop takes ≈ 1h 15m, and the DEL→KTM international segment adds another ≈ 1h 25m, making the 1-stop total ≈ 4–5h depending on connection time. Vistara no longer operates as an independent airline (merged into Air India in 2024), and Go First and Jet Airways remain defunct as of 2026. Himalaya Airlines, the Chinese-Nepali joint venture, serves KTM but from Chengdu and other Chinese cities, not from Lucknow.
Lucknow to Kathmandu spans ≈ 580 km — shorter than many Indian domestic trunk routes. On a non-stop ATR 72, block time is ≈ 1h 15m; on a 1-stop via Delhi the same distance takes ≈ 4–5h with layover. The airway between LKO and KTM tracks north-east across the Indo-Gangetic plain before the terrain abruptly rises as the aircraft crosses into Nepal. On clear days, passengers seated on the right side of the aircraft (window seats A on an ATR) can spot the Himalayan foothills, and on rare winter days the main Himalayan chain — including Langtang and the Annapurna massif — may be visible. Tribhuvan Airport (KTM) has a notoriously short runway hemmed in by hills, so the approach can feel steep; this is normal.
Nepal's tourism year runs in two distinct peaks separated by the monsoon trough. Autumn (October–November) is the prime trekking window — Everest and Annapurna trails fill up, and flights from Lucknow to Kathmandu command their highest fares. Spring (March–April) is the second peak for high-altitude trekking and rhododendron blooms; demand is high but slightly lower than autumn. The cheapest fares appear during the monsoon (June–August), when flights are cheapest but mountain visibility is poor. For the best value at a reasonable weather window, target December–February (cold but clear) or May before monsoon onset. Book ≈ 4–6 weeks ahead for shoulder season, ≈ 8–10 weeks ahead for peak autumn.
Because the LKO→KTM sector is short, fare differences between carriers are relatively modest. On Buddha Air's direct services, economy typically includes ≈ 20 kg checked baggage with a 7 kg cabin allowance. For IndiGo's international segment out of Delhi, checked baggage is typically 20–23 kg on standard international fares; the domestic LKO→DEL leg includes only 15 kg on base fares, so top up if you're carrying more. Air India offers ≈ 25 kg checked on both the domestic and international segments. Cabin bags are capped at 7 kg. Internal Nepal flights (for reaching Pokhara, Lukla, or other mountain airstrips) have much tighter weight restrictions — typically 15 kg total — so pack light if you plan mountain excursions.
Departures from Lucknow use Chaudhary Charan Singh International Airport (LKO), a modern single-terminal facility located ≈ 14 km south-west of the city centre; airport taxis and pre-paid cabs from Hazratganj take ≈ 30–40 minutes. When connecting through Delhi, international flights to Kathmandu depart from Terminal 3 (T3) at Indira Gandhi International Airport (DEL) — the largest terminal in India and well signposted for international connections. Tribhuvan International Airport (KTM) is Nepal's only international gateway, situated ≈ 6 km east of Thamel, the main tourist neighbourhood. Pre-paid taxis at KTM are recommended over meter cabs; the ride to Thamel or Durbar Marg takes ≈ 20–40 minutes depending on Kathmandu's famously unpredictable traffic.
Indian citizens enjoy visa-free, fee-free, unrestricted-stay access to Nepal under the 1950 Treaty of Peace and Friendship between India and Nepal. You can enter with a valid Indian passport or a government-issued voter ID card — no advance visa application, no biometrics, and no entry fee. The same open-border policy also applies to the land crossings at Sonauli (closest to Lucknow, ≈ 300 km by road), Nautanwa, and Raxaul. Indian rupees are accepted in Nepal at a fixed exchange rate (1 INR ≈ 1.6 NPR in 2026), though Nepali shops may be reluctant to accept denominations above ₹100. ATMs dispensing NPR are widely available in Kathmandu and Pokhara. For full current entry rules visit /visas.
Kathmandu is more than a transit hub to trekking country — the Kathmandu Valley alone holds seven UNESCO World Heritage Sites. Pashupatinath Temple (the holiest Hindu site in Nepal), Boudhanath stupa, Swayambhunath (the 'Monkey Temple'), and the medieval royal squares of Patan and Bhaktapur are all within 30 km of the airport. Day trips to Pokhara (the gateway to the Annapurna circuit) take ≈ 1h by domestic flight or 6–7h by tourist bus. The best seasons for longer treks are October–November and March–April. For city sightseeing, December–February (cool but rarely cold at valley altitude of ≈ 1,400 m) is a comfortable choice. Budget travellers should note that Lucknow to Kathmandu is one of the most cost-effective international routes from northern India, with Thamel guesthouses and daal-bhat meals available at very modest prices.
Yes, occasionally — Buddha Air has operated seasonal non-stop ATR 72 flights between LKO and KTM, taking ≈ 1h 15m. However, this route is not always active, especially during the monsoon. Check current schedules on FlightGPT; if no direct is listed, the 1-stop via Delhi is the standard fallback.
A non-stop takes ≈ 1h 15m. The most common 1-stop routing via Delhi totals ≈ 4–5h including the connection time. Via other hubs it is longer. The distance is ≈ 580 km — quite short for an international flight.
No. Indians can enter Nepal without a visa, without an entry fee, and with no restriction on the duration of stay. A valid Indian passport or a government-issued voter ID card is sufficient for entry at Tribhuvan Airport in Kathmandu.
Fares vary by season and airline, but economy tickets typically range from ≈ ₹5,000 to ₹14,000 on 1-stop itineraries via Delhi. Direct services on Buddha Air, when available, can be priced similarly or slightly higher depending on demand. Live fares are searchable on FlightGPT.
October–November (autumn trekking season) and March–April (spring trekking season) are the most popular — but also the most expensive — times to fly. June–August (monsoon) offers the lowest fares, though mountain treks are muddy and visibility poor. December–February is quiet, cheap, and clear — good for city sightseeing.
Yes. The Sonauli border crossing (Gorakhpur–Bhairahawa) is ≈ 280 km from Lucknow by road. From Sonauli it's a further ≈ 300 km (5–6h by bus or shared jeep) to Kathmandu via Mugling. The total road trip is ≈ 12–16h and considerably cheaper than flying, but very long. Tourist buses from Gorakhpur to Kathmandu run daily and can be booked at Gorakhpur railway station.

Lucknow to Kathmandu prices swing with demand, season and lead time more than with any single airline. The reliable lever is comparison: pull every LKO–KTM fare at once and shift your date by a day or two. Mid-week and red-eye departures on Buddha Air, IndiGo, Air India are usually where the cheapest seats sit.
For a same-week Lucknow–Kathmandu trip, the trick is to check all carriers at once rather than one app at a time. FlightGPT's live LKO-KTM search does exactly that — red-eye and early-morning departures often carry the lowest last-minute prices. Enter your date above to compare instantly.
Most travellers prefer the Lucknow to Kathmandu non-stop option. The direct Lucknow-Kathmandu flight time is ≈ 1h 15m (non-stop) / 3–5h (1-stop).

FlightGPT lets you filter by "Direct only" or compare both side by side — useful when you want the cheapest Lucknow Kathmandu ticket but are open to a layover.
On Lucknow to Kathmandu, the headline price and the price you actually pay can differ once baggage and seat selection are added. That's why FlightGPT compares fully-bundled Lucknow Kathmandu fares across Buddha Air, IndiGo, Air India — the cheapest all-in option, not the lowest sticker that balloons at checkout.
