Jolly Grant Airport (DED) is a Tier-2 domestic hub serving Uttarakhand. International operations from DED are limited; Kathmandu is not among the current overseas routes. The workaround is a short 55–60 minute hop to Delhi T3, from where IndiGo, Air India, and Nepal Airlines each operate multiple daily DEL–KTM services. Delhi T3 handles the connection entirely within the same international departure wing, though domestic arrivals land at T2/T1 — travellers must take the airside shuttle to T3 or exit and enter T3 separately, so factor in at least 3 hours at Delhi.
IndiGo is the most frequent operator on DEL–KTM with 2–3 daily non-stops and typically the cheapest published fare. Air India provides a slightly wider seat and includes a 25 kg check-in bag in economy. Nepal Airlines (RA) flies Boeing 757s and Airbus A330s on this route and is popular with returning Nepali workers — its fares are occasionally competitive but availability can be thin. The DEL–KTM flight itself takes about 1h 25–35m and offers stunning Himalayan views from the right side of the aircraft on clear mornings.
Nepal's prime trekking windows are March–May and October–November, corresponding to spring rhododendron blooms and post-monsoon clear skies on routes like Everest Base Camp and Annapurna Circuit. These months see high demand from Uttarakhand and north India travellers, pushing combined DED–KTM fares up 20–35%. Monsoon (June–September) is the cheapest period to fly — fares can drop to ₹8,000–₹12,000 return — but mountain views are obscured and some trekking routes are inaccessible. Book October travel by August for best availability.
Adventurous travellers sometimes take the overland route: bus from Dehradun to Sunauli/Belahiya border crossing (≈ 10–12 hours), then bus or shared jeep to Kathmandu (another 6–8 hours). This adds significant time but cuts cost dramatically and allows stops at Lumbini (the Buddha's birthplace). The Lucknow–Sunauli option via train+bus is also popular. For those with limited time, the DEL connection wins. Note that overland entry still requires Indian passport or voter ID.
As of June 2026, a combined DED–DEL–KTM return itinerary in economy costs approximately ₹9,000–₹18,000 depending on season and how far in advance you book. IndiGo's cheapest fares include only a 7 kg cabin bag on the domestic DED–DEL leg; add 15–20 kg for luggage going to Nepal. Air India's DEL–KTM economy includes a 25 kg check-in allowance, making it a better value if travelling with large bags. Nepal's currency (NPR) is best exchanged at Tribhuvan Airport on arrival.
Indian citizens do not require a visa to enter Nepal under the 1950 Treaty of Peace and Friendship — a major advantage over all other international destinations. A valid Indian passport or government-issued voter ID card suffices at the border or airport. There is no official fee and no advance documentation required. However, carry original documents (photocopies are sometimes questioned). If entering at Tribhuvan Airport, immigration for Indians is typically faster than for third-country nationals. Visit /visas for the latest guidance on any bilateral updates.
Pashupatinath Temple, Boudhanath Stupa, and Swayambhunath (Monkey Temple) are the cultural anchors of Kathmandu — all within 30 minutes of the airport. Thamel is the backpacker-turned-tourist hub with gear shops, cafes, and live music. Day trips to Pokhara (by domestic flight, ≈ 25 min) open access to the Annapurna range. For Uttarakhand residents, Kathmandu feels culturally familiar — shared Himalayan cuisine, Hindu temples, and similar mountain landscapes. Altitude in the valley is ≈ 1,400 m, so no major acclimatisation is needed compared with Ladakh or Spiti.
