Looking for cheap flights from Tiruchirappalli to Kathmandu? FlightGPT compares live TRZ to KTM fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side.

For most Tiruchirappalli residents, Chennai (MAA) is the closer and more frequent connection — IndiGo and Air India run multiple TRZ–MAA flights daily (≈ 1h 10m), and both carriers operate daily MAA–KTM service. Bengaluru (BLR) adds marginally more choice of schedule but involves a slightly longer domestic hop (≈ 1h 20m from TRZ). If your preferred timing aligns with a BLR departure, it is a perfectly good option. Chennai's T2 international terminal is the departure point for Kathmandu flights and is generally less congested than BLR's T2 during morning banks.
As of June 2026, round-trip economy fares on a single itinerary from TRZ to KTM run approximately ₹14,000–₹24,000 depending on season and how far ahead you book. Air India and IndiGo are usually within ₹2,000–₹4,000 of each other; Himalaya Airlines sometimes offers competitive prices on the MAA–KTM sector. The cheapest windows are typically January–February (after New Year) and late August–September. Booking 4–6 weeks ahead is generally sufficient for this route; demand is moderate and last-minute fares rarely spike as dramatically as Gulf routes.
Tribhuvan International Airport (KTM) is Kathmandu's only commercial airport and one of Asia's more challenging — it sits in a valley, has a single runway, and is prone to delays in poor visibility. The airport has one international terminal and one domestic terminal connected by a short walk. Baggage claim can be slow during busy arrival banks (midday and early afternoon). Taxis are available outside arrivals; agree on a price before getting in (around NPR 700–900 to the Thamel tourist district, ≈ 7 km). Pre-paid taxi booths inside arrivals are the safest option.
Indian nationals are unique in that they can enter Nepal without a visa and without a passport — a valid Aadhaar card, voter ID or driving licence is accepted at the immigration counter. This applies at Tribhuvan International Airport as well as at land borders. There is no fee and no form to fill beyond a basic arrival card. However, airlines flying to Kathmandu typically require a passport for international check-in; confirm with your carrier whether a national ID is accepted at TRZ and MAA check-in desks. Air India and IndiGo generally allow Indian ID cards for the India–Nepal sector.
Nepal maintains UTC+5:45 — a quirky 15-minute offset ahead of IST. In practice this means if you land in Kathmandu at what feels like your 14:00, local clocks show 14:15. It is a small difference but worth noting when scheduling airport pickups. TRZ–MAA takes ≈ 1h 10m; MAA–KTM is ≈ 2h 20m non-stop. With a 90-minute connection you can complete the journey in about 5h 30m. Most booked itineraries show 6–7 hours total including the connection buffer. Nepal is best explored with a rental car or local guide given variable mountain road conditions.
October and November are the gold standard for Kathmandu and trekking in Nepal — post-monsoon skies are crystal clear, temperatures are comfortable (15–22°C in the valley) and mountain views are spectacular. March–May is the second-best window, popular for rhododendron blooms and pre-monsoon trekking to Everest Base Camp. Monsoon (June–September) brings leeches on trails but lush green scenery and lower hotel prices. December–February is cold at altitude but city sightseeing is fine. From Tiruchirappalli, October and March departures are ideal for combining good weather with reasonable airfares.
