As of 2026, there is no nonstop commercial flight between Tiruchirappalli (TRZ) and Kathmandu (KTM). The most practical routing is a one-stop connection through Chennai (MAA), with IndiGo and Air India offering reasonably timed connections. Some passengers also connect via Bengaluru (BLR) with IndiGo or Air India. The hub-and-spoke journey typically involves a 1–2 hour layover at the connecting airport. Total elapsed travel time from TRZ to KTM (door-to-gate) is approximately 6–9 hours depending on connection timing. Occasionally, travellers also route via Hyderabad or Delhi for better onward availability to Kathmandu.
The most efficient one-stop option from TRZ to KTM is TRZ→MAA→KTM on IndiGo, which operates both sectors and offers convenient connections at Chennai airport. The TRZ–MAA segment takes approximately 50–60 minutes, and the MAA–KTM nonstop segment takes around 3 hours 30 minutes to 3 hours 45 minutes. IndiGo operates this combination with good frequency. Air India also provides a competitive TRZ→MAA→KTM itinerary. Alternatively, TRZ→BLR→KTM via IndiGo or Air India Express is worth checking, as Bengaluru has good KTM frequencies. Total airborne time for either routing is typically 4.5–5.5 hours, not counting the layover.
Indian citizens enjoy a uniquely privileged entry into Nepal — no visa, no passport required. Indian nationals can enter Nepal using a valid Indian passport OR any of several photo identity documents, including an Aadhaar card, a voter ID card, or a driving licence. There is no visa fee and no pre-registration needed. Indians can stay in Nepal without a visa, as the two countries share an open border under the 1950 Treaty of Peace and Friendship. However, for air travel, airlines typically require a valid passport or a valid government-issued photo ID with date-of-birth. Confirm with your carrier what ID they accept at check-in.
Tiruchirappalli International Airport (TRZ) is a compact airport serving central Tamil Nadu, approximately 5 km from the city centre. It has a single integrated terminal handling both domestic and international departures. For the onward connection to Kathmandu, travellers boarding in Trichy will fly to their connecting hub (Chennai or Bengaluru) domestically first. For domestic-to-international connections at Chennai or Bengaluru, passengers must collect their baggage and re-check it (unlike international-to-international through-checks) if on separate tickets. Booking a single-ticket itinerary through IndiGo or Air India is therefore strongly recommended to ensure baggage is checked through to KTM.
Tribhuvan International Airport (KTM) is Nepal's sole international gateway and one of the most technically challenging airports to approach due to the surrounding Himalayan terrain. The airport has a single runway and limited nighttime landing capability, which makes it prone to disruption during poor weather, particularly during monsoon season (June–September). Indian passport holders clear immigration quickly under the open-border arrangement. The airport is just 6 km from Kathmandu's Thamel tourist district. Prepaid taxis are available from the arrivals area; negotiate or use the prepaid counter to avoid inflated fares. Uber does not operate in Kathmandu — local apps like Pathao and InDrive are popular.
The best seasons for Kathmandu travel are spring (March–May) and autumn (September–November), which coincide with clear skies and peak trekking season. Monsoon months (June–September) bring fog, rain, and significant flight delays and cancellations at KTM. Winter (December–February) is cold but generally clear for Kathmandu city visits, though high-altitude trekking requires serious preparation. Pilgrim travel to Pashupatinath spikes during Shivaratri (February–March). Booking at least 30–45 days ahead for the TRZ–connecting hub leg is advisable during Indian school vacations (April–May and October), when domestic seat availability tightens.
Since there is no nonstop TRZ–KTM flight, the total fare is the sum of TRZ–hub and hub–KTM segments. A combined economy itinerary on IndiGo (TRZ→MAA→KTM) typically ranges from ≈ ₹10,000 to ₹22,000 one-way all-in during off-peak periods. Booking a through-ticket (single PNR or interline) is preferable for missed-connection protection. Watch for IndiGo's seasonal fare promotions on the MAA–KTM sector, which can substantially reduce the total cost. Air India tends to be slightly more expensive on this routing but offers checked baggage in economy fares. During trekking season (October–November), KTM-bound flights fill quickly and prices rise across all carriers.
Kathmandu's climate varies dramatically by season — pack light layers for the shoulder season, warm jackets for winter, and waterproof gear for monsoon. Nepal has no significant restrictions on common personal items. Indian currency (INR) is widely accepted in Nepal at a fixed exchange rate, and Indian debit/credit cards work at most Kathmandu ATMs. Bringing a mix of ₹100 and ₹500 notes in small denominations is practical. Do not carry INR 2,000 notes as they are not accepted. Nepali customs allows duty-free import of personal-use quantities of electronics, medicines, and general goods. Trekking gear is widely rentable in Kathmandu's Thamel district if you prefer not to fly with bulky equipment.
