IndiGo Pauses Kolkata–Siem Reap Flights Until Late September

IndiGo has temporarily suspended flights to Siem Reap as part of a wider adjustment to its international network, removing the direct Kolkata–Siem Reap link from 3 July 2026 until 30 September 2026.

The airline’s official notice says the change affects six international destinations. Langkawi, Krabi, Ho Chi Minh City, Hong Kong and Shanghai were listed from 1 July, while Siem Reap is affected from 3 July. IndiGo said the move is linked to softer demand in the upcoming quarter, higher operating costs and continued airspace restrictions.

Route affected

The Cambodia service connected Kolkata Airport (CCU) with Siem Reap Angkor International Airport (SAI), the main airport for Angkor Wat and the wider Siem Reap temple region. When IndiGo announced the route in October 2025, it described the service as three weekly flights operated with Airbus A320neo aircraft, departing Kolkata on Mondays, Thursdays and Saturdays and returning from Siem Reap the same days.

For travelers coming from India, the pause removes the only direct IndiGo-operated link into Siem Reap during the suspension period. Trips to Angkor may need to be routed through other hubs such as Bangkok, Singapore, Kuala Lumpur or Phnom Penh, depending on airline schedules and available connections.

Bookings and resumption plans

IndiGo says the affected services are suspended until 30 September 2026 and that bookings for impacted services will resume from 1 October 2026. The airline also says it could reinstate services earlier if market conditions improve.

Anyone planning Cambodia travel around July, August or September should check their booking directly with IndiGo or the ticketing agent, especially if the itinerary includes flight numbers 6E1655 or 6E1656 between Kolkata and Siem Reap. Travelers planning an Angkor itinerary should leave extra buffer for revised routings, overnight connections or an arrival through Phnom Penh followed by a domestic flight, bus or private transfer to Siem Reap.

Khmer Times and Kiripost both reported Cambodian aviation officials describing the suspension as temporary and commercially driven rather than a sign that Cambodia is closing or restricting access. Local reports also note that Siem Reap has recently seen other regional route pauses, including Firefly’s Kuala Lumpur–Siem Reap service, which may reduce direct-flight options for some visitors.

Practical planning notes

• Travel dates: the official IndiGo suspension window for Siem Reap starts on 3 July 2026 and runs until 30 September 2026.
• Airport: the affected destination is Siem Reap Angkor International Airport (SAI), used for access to Angkor Wat and Siem Reap province.
• Alternative routes: travelers may need to connect through regional hubs or fly into Phnom Penh before continuing to Siem Reap.
• Uncertainty: IndiGo says bookings resume from 1 October, but passengers should verify actual flight availability before building a fixed itinerary around the route’s return.
