This is a well-served nonstop international sector. SriLankan Airlines, the flag carrier, operates the route alongside IndiGo, with Air India also appearing on some schedules as of 2026. Combined, these carriers offer several departures across the week, giving travellers a useful spread of timings for both leisure and business trips. SriLankan tends to suit travellers connecting onward across its Colombo hub, while IndiGo competes on point-to-point fares. If you are planning the journey home, our companion guide on Colombo to Trivandrum flights mirrors the same airlines and short flying time across the Palk Strait.
Colombo sits only about 340 km from Thiruvananthapuram, making this one of the shortest international flights from India. Scheduled nonstop airborne time is typically around 1 hour to 1 hour 15 minutes, with SriLankan's fastest sometimes clocking close to an hour. Including international check-in, immigration and security, plan a door-to-door window of three to four hours despite the brief flight. Because it is international, you must arrive earlier than for a domestic hop, so factor extra time at Trivandrum for passport control and at Colombo's Bandaranaike airport on arrival, where immigration queues can vary by time of day.
Sri Lanka requires an Electronic Travel Authorization (ETA) for Indian visitors, but as of 2026 the ETA fee has been waived for Indian nationals, making short tourist visits effectively free of visa cost. The free ETA is still mandatory: apply online through the official portal before boarding and carry the printed approval, since airlines check it at Trivandrum. The standard tourist stay is up to 30 days. Carry a passport valid at least six months, a return ticket and proof of accommodation. Avoid third-party sites that charge fees; only the official government portal is correct, as our visa requirements overview also notes.
Fares on Trivandrum–Colombo are reasonable given the short distance and competition, but they still move with season. The peak runs through Sri Lanka's dry tourist season and the year-end holidays, when both leisure and visiting-friends-and-relatives demand rises. Better value typically appears in the shoulder and off-peak months, including parts of the southwest monsoon. Booking two to four weeks ahead is usually enough on this short international sector, and mid-week departures often undercut weekends. Watch for SriLankan and IndiGo promotional fares, and remember that the now-free ETA removes a cost that travellers previously had to budget separately.
Even on a one-hour international flight, baggage rules follow international fare structures, which often differ from domestic norms. SriLankan typically includes a checked allowance on its international economy fares, while IndiGo's international fares have their own allowance that may be more generous than its domestic saver fares. Always confirm the exact checked and cabin limits for your specific fare, as international tickets sometimes bundle more baggage than a comparable domestic hop. If you are carrying Kerala spices, cashews or gifts, weigh your bag in advance, since excess-baggage fees on international sectors are charged at international rates.
You depart from Trivandrum International Airport (TRV), Kerala's southern international gateway, which handles the Colombo flights from its international section. On arrival you land at Bandaranaike International Airport (CMB) in Katunayake, about 35 km north of central Colombo, so allow road time into the city or onward to Negombo, which is much closer to the airport. Both airports are accustomed to this short cross-strait traffic. Because it is international, ensure your ETA approval and travel documents are ready before you reach TRV's check-in, where airline staff verify Sri Lankan entry authorisation prior to issuing boarding passes.
The route carries Kerala tourists exploring Sri Lanka's beaches, hill country and cultural triangle, business travellers, students, and a strong flow of visiting-friends-and-relatives traffic given deep historical and family ties across the strait. Pilgrims and medical travellers also use the link. Many leisure travellers pair Colombo with onward domestic Sri Lankan travel via SriLankan's hub. If you are planning a wider South India to Sri Lanka trip and want to compare gateways, see Chennai to Colombo flights, another popular nonstop crossing, and browse our broader travel guides for itinerary ideas in Sri Lanka.
Apply for the free Sri Lanka ETA on the official portal well before departure and carry the printout, since it is checked at Trivandrum. Arrive at TRV at least two to three hours early for the international departure to clear immigration and security comfortably. Confirm your fare's baggage allowance, which on international tickets may be more generous than domestic. Keep some Sri Lankan rupees or a travel card for arrival at Bandaranaike, and book onward airport transfers in advance, especially if heading beyond Negombo into Colombo at peak traffic hours after a short evening flight.
