Historically, Buddha Air and Shree Airlines have operated charter or scheduled direct services between Patna (PAT) and Kathmandu (KTM) — typically using turbo-prop ATR 72 aircraft, cutting through Bihar's flat plains and the Terai in just over an hour. However, direct frequencies are limited and seasonal — always verify current schedules at the time of booking. If no direct is available, the most practical connection is Patna → Delhi (≈ 1h 20m on IndiGo) then Delhi → Kathmandu (≈ 1h 25m on Air India, Yeti Airlines, or IndiGo), with a convenient 2h DEL layover making total travel around 4.5h. Lucknow (LKO, ≈ 55 min from PAT) is another option with direct Kathmandu services.
Direct Economy fares (when available) on the PAT–KTM route typically range from ≈ ₹5,000–₹11,000 one-way. Via Delhi, combined fares are ≈ ₹6,000–₹14,000. The cheapest months are January–February (off-peak, post-Christmas) and September–early October (post-monsoon, before Dashain). Dashain and Tihar festivals in October–November drive Nepal-bound fares sharply higher — book 8–12 weeks ahead. Avoid buying at the last minute as both segments — especially the PAT–DEL domestic leg — are frequently at near-full capacity. Nepal Airlines occasionally runs promotional fares from DEL–KTM at ≈ ₹3,500–₹5,000 one-way.
Indian nationals enjoy the unique privilege of entering Nepal without a visa — no stamp, no fee, no prior application. A valid Indian passport (no minimum validity stipulated, but 6 months recommended) or a government-issued voter ID card is sufficient. Aadhaar alone is generally not accepted at immigration; carry your passport or voter ID. There are no biometric requirements or arrival cards for Indians (though this may change — confirm at Tribhuvan airport). Indian Rupees are widely accepted in Kathmandu (rate ≈ 1 INR = 1.6 NPR). For full travel requirements see /visas.
Kathmandu's Tribhuvan International Airport (KTM) is a single-runway airport with a new Terminal 2 under phased development. Arrival procedures for Indian citizens are notably swift — skip the visa-on-arrival queue entirely, proceed to the 'SAARC nationals' lane, and clear immigration in minutes. The airport is ≈ 6 km from Thamel, Kathmandu's tourism hub. Metered yellow taxis charge ≈ NPR 700–1,000 to Thamel; app-based taxis (Pathao, inDrive) are ≈ NPR 400–600. The airport road is prone to congestion during morning and evening hours, so factor ≈ 30–60 minutes depending on traffic.
October–November (post-monsoon) is widely regarded as the finest time to visit Kathmandu — skies are crystal clear, Himalayan views (including the Langtang and Ganesh Himal ranges visible from the valley) are spectacular, and the Dashain and Tihar festivals add vivid local colour. March–May (spring) is the second favourite window: rhododendrons bloom in the hills and temperatures are pleasant (15–22°C). The summer monsoon (June–September) brings heavy rains but lush greenery and fewer tourist crowds. Winters (December–February) are cold (overnight near 2°C) but offer the cheapest fares and uncrowded heritage sites.
Kathmandu's UNESCO World Heritage sites span seven historic zones: Pashupatinath Temple (one of Hinduism's most sacred shrines — especially meaningful for Bihar's devout visitors), Swayambhunath (Monkey Temple), Boudhanath Stupa, and Patan Durbar Square are all within 30 minutes of city centre. The bustling Thamel district is a backpacker favourite with abundant Indian vegetarian restaurants. Day trips include Nagarkot (sunrise Himalayan view), Bhaktapur Durbar Square (≈ 16 km), and Dhulikhel. A short 25-minute flight from Kathmandu reaches Pokhara and Phewa Lake. For a full travel guide see /destinations/kathmandu.
Domestic and regional carriers on the PAT–KTM sector typically allow 15–20 kg check-in; verify at booking as low-cost fares often include only 15 kg. Nepal currency (NPR) cannot be purchased in India; exchange USD or INR at Tribhuvan airport or in Thamel. Indian SIM cards do not get complimentary roaming in Nepal — buy a Ncell or NTC local SIM at the airport (≈ NPR 500 with 4 GB data, valid 28 days). Nepal's electricity is 230V/50Hz with Type C/D/M plugs; most Indian plugs fit without adaptor. Note that fares as of June 2026 can differ — always check live prices before booking.
