Indian carrier IndiGo will resume direct flights between Kolkata (CCU) and Siem Reap (SAI) starting October 1, 2026, operating three times a week on Mondays, Thursdays, and Saturdays using an Airbus A320neo. The route was originally launched in November 2025 but was suspended due to seasonal factors, according to Cambodia’s State Secretariat of Civil Aviation.
Officials frame the resumption as a way to strengthen bilateral ties between India and Cambodia and create opportunities for joint tourism promotion, noting that India is the world’s second-largest tourism market. The route gives travelers from eastern India a direct link to Angkor Wat without connecting through Bangkok, Kuala Lumpur, or Ho Chi Minh City.
Why This Matters for Travelers
A direct Kolkata-Siem Reap route removes a layover for one of India’s fastest-growing outbound tourism corridors, cutting total travel time and connection risk for visitors heading straight to Angkor Wat and the wider Siem Reap area. It also continues a broader trend of Siem Reap International Airport rebuilding international connectivity after several lean years, alongside other regional route announcements this year.
What Travelers Should Do
If you’re planning a Kolkata-Siem Reap trip from October 1 onward, book directly through IndiGo given the limited three-times-a-week schedule, and confirm your Cambodia e-visa or visa-on-arrival requirements well ahead of departure, since Cambodia’s entry rules can change. Because this is a resumed rather than a long-running permanent route, it’s worth checking IndiGo’s schedule close to your travel dates in case frequency changes again.
FAQ
When does the IndiGo Kolkata-Siem Reap route start?
October 1, 2026, operating three times a week (Monday, Thursday, Saturday) on an Airbus A320neo.
Is this a new route or a resumption?
It’s a resumption — IndiGo first launched the route in November 2025 but suspended it due to seasonal demand factors before bringing it back for October 2026.
Do I still need a visa to fly into Siem Reap from India?
Yes. Indian citizens require a visa to enter Cambodia, available as an e-visa in advance or visa-on-arrival at Siem Reap International Airport. This flight announcement doesn’t change Cambodia’s visa requirements.
Are there other direct flights between India and Siem Reap?
As of this announcement, IndiGo’s Kolkata-Siem Reap service is the direct link on this specific route; travelers from other Indian cities still typically connect via Bangkok, Kuala Lumpur, Singapore, or Ho Chi Minh City.
Will this route definitely continue year-round?
Not guaranteed — the route was suspended once before for seasonal reasons, so travelers should check IndiGo’s current schedule close to their travel dates rather than assuming a long-term daily service.
