How to Reach Siem Reap from Mumbai: Flights, Routes and Visa (2026)

Mumbai is one of the biggest Indian metropolises and well connected with the rest of the world, but not yet with Cambodia. Flights from Chhatrapati Shivaji Maharaj International Airport (BOM) to Siem Reap all stop somewhere, so the real decision is which city you change planes in. This page compares the six hubs with times and rupee fares, then covers the ride from the airport into town, the visa and arrival card, and the Phnom Penh alternative. If you would rather not stitch flights together yourself, our Cambodia tour packages from Mumbai can include the flights and the airport pickup.

Is there a direct flight from Mumbai to Siem Reap?

No, not as of November 2026. There are no non-stop flights available between Mumbai and Siem Reap, and there is no direct connectivity by railways or roadways either.

The only nonstop between India and Siem Reap is IndiGo's Kolkata flight, 6E 1655. It launched on 13 November 2025, was paused from 3 July to 30 September 2026, and restarted on 1 October 2026 on Mondays, Thursdays and Saturdays. IndiGo sells it with a connection from Mumbai, which makes it the closest thing to a direct flight that a Mumbai traveller can book today.

Two warnings about what you may read elsewhere. Some flight sites still show Siem Reap as "REP" and hint at nonstop options. REP closed to commercial traffic on 16 October 2023, and every flight now uses SAI, about 50 km east of town rather than the old airport's 7 km. Older guides also suggest flying to Bangkok and continuing by road. The Thailand-Cambodia land border at Poipet has been closed since mid-2025, so that plan no longer works. Take the one-hour flight from Bangkok instead.

Mumbai to Siem Reap flights: the best 1-stop routes

Six one-stop or two-stop routings work from Mumbai. Bangkok wins on frequency and speed, Kolkata on price and simplicity, and Ho Chi Minh City or Hanoi if you are adding Vietnam to the trip.

Fares are from Google Flights, Skyscanner and singaporeair.com on 2 November 2026 and change daily. Some are one way and some return, as marked, so compare like with like. Times include the connection. Rome2Rio counts about 41 one-stop flights a week from Mumbai to Siem Reap, averaging 8 hours 1 minute.

Which airline has the most flights? Thai Airways and Bangkok Airways, both connecting through Bangkok every day. Singapore Airlines adds a daily link through Changi. The Hong Kong connections some older pages list are not sold as practical routings today.

The all-IndiGo route via Kolkata, step by step

This route stays in India until the final leg. You pay in rupees on one airline, clear Indian emigration in Kolkata, and never set foot in a foreign transit airport.

1. Search goindigo.in for Mumbai to Siem Reap as one booking. The site builds the connection through Kolkata, so your bag is checked through to SAI.

2. Pick an evening Mumbai departure on a Wednesday, Friday or Sunday. The 1,665 km hop to Kolkata takes about 2 hours 45 minutes.

3. In Kolkata, move from the domestic side to international departures, where you clear Indian emigration and security. Allow at least 3 hours between flights.

4. Board 6E 1655 at 03:35. The 1,959 km flight takes about 3 hours.

5. Land at SAI at 08:00 local time with your e-visa and e-Arrival QR code ready.

6. Take a taxi into town (the first airport shuttle leaves at 9:30 am) and check in early, or rest and head to Angkor in the afternoon.

The catch is the hour. You spend most of the night in Kolkata airport and on the plane, so keep the first day in Siem Reap slow.

Mumbai to Siem Reap distance, flight time and time difference

The fastest Mumbai to Siem Reap trip takes about 7 hours 15 minutes with a tight Bangkok connection. Most bookable itineraries take 8 to 12 hours.

Distances were calculated by our desk from airport coordinates. The 3,365 km figure on older pages, this one included until now, measures to the closed REP airport.

Set your watch forward 90 minutes when you land. The late-night THAI departures from Mumbai reach Bangkok around dawn and Siem Reap by late morning.

Mumbai to Siem Reap flight fares and the cheapest time to fly

Budget Rs 35,000 to Rs 56,000 per person for an economy return. On 2 November 2026 the cheapest one-way fare was IndiGo through Kolkata at about Rs 17,000 (Skyscanner). Singapore Airlines started at Rs 38,514, and THAI's Bangkok connection at Rs 56,039 return.

Skyscanner's data shows November as the cheapest month to fly this route. Prices climb from mid-December to early January, when Cambodia's dry, cool peak meets Indian school holidays and Christmas, and Diwali weeks are expensive too. May to September is the wet season. Fares soften, the temples turn green and quiet, and most of the rain falls in short afternoon bursts.

Book 6 to 10 weeks ahead for peak dates. Price the IndiGo Kolkata option first, then check whether THAI or Singapore Airlines is close enough to justify the faster connection and the meals. For month-by-month weather, see the best time to visit Siem Reap.

Connecting without stress: baggage, layovers and transit

Book the whole trip on one ticket if you can. On a single booking your bag is checked through to Siem Reap and the airline rebooks you if the first flight runs late. THAI, Singapore Airlines, Vietnam Airlines and IndiGo all sell Mumbai to Siem Reap as one ticket.

Separate low-cost tickets save money but move the risk to you. If you land at Bangkok Suvarnabhumi and fly on from Don Mueang, you collect your bag, pass Thai immigration and cross the city, so allow at least 4 hours. Entering Thailand needs the free Thailand Digital Arrival Card, filed online within 3 days before you land, on top of Thailand's entry rules for Indian passports. A self-transfer in Hanoi or Ho Chi Minh City needs a Vietnamese e-visa before you fly.

On a one-way ticket, airlines may ask at the Mumbai check-in counter for proof of onward travel out of Cambodia. Keep your return booking on your phone.

A long layover can work in your favour. A night in Bangkok or a day in Singapore breaks the trip well for families and older travellers.

Siem Reap-Angkor International Airport (SAI) to town

SAI opened in October 2023 about 50 km east of Siem Reap town, so the ride in takes about an hour on the expressway. From the arrivals hall you can take the shuttle bus, book a taxi, arrange a tuk-tuk or use a hotel pickup.

A taxi from the airport is still the safest option after a night flight. Carry small US dollar notes. Dollars are accepted everywhere alongside the Cambodian riel.

Cambodia visa and e-Arrival card for Indians

Indian passport holders need a visa for Cambodia. Two documents and one form get you through SAI quickly.

• Visa. The tourist e-visa costs US$30 (about Rs 2,850) for 30 days, single entry, at evisa.gov.kh. Apply at least 3 working days ahead. A visa on arrival is also issued at SAI for US$30 in cash; bring clean, untorn notes.

• Cambodia e-Arrival (CeA) card. Free, at arrival.gov.kh or in the CeA app, filled in within 7 days before you land. It replaces the paper arrival, health and customs forms and is required for every air arrival.

• Passport. At least 6 months' validity on arrival and a blank page.

Alternative: fly Mumbai to Phnom Penh, then Siem Reap

Flying into Phnom Penh's new Techo International Airport (KTI) is sometimes cheaper. On 2 November 2026 Skyscanner India's Cambodia route page listed lead fares of Rs 27,378 to Phnom Penh and Rs 34,681 to Siem Reap, so price both airports for your own dates. From Phnom Penh, Siem Reap is a 5 to 6 hour bus ride (about US$15 to 19) or a flight of about 50 minutes.

It only pays off if you are visiting both cities. For an Angkor-focused trip of 4 to 5 days, fly straight into SAI and keep the saving in hours, not rupees.

Mumbai to Angkor Wat

Angkor Wat is about 7 km north of Siem Reap town and roughly an hour from SAI. Most travellers check in, sleep off the flight, and catch sunrise at Angkor Wat the next morning.

You need an Angkor Pass. It costs US$37 for 1 day, US$62 for 3 days (used within 7 days) and US$72 for 7 days (used within 30 days). Angkor Wat opens at 5 am for sunrise and closes at 5:30 pm. Ticket details are on our Angkor Wat guide, and the other temples worth your time are in Siem Reap places to visit.

Tips for Mumbai and Pune travellers

• International flights to Southeast Asia leave from Terminal 2 at Chhatrapati Shivaji Maharaj International Airport. Arrive 3 hours before departure, and more on a Friday night. The IndiGo Kolkata routing is different, because its first leg is a domestic flight. IndiGo runs some Mumbai domestic flights from Terminal 1, and some from Navi Mumbai, so read the airport and terminal on your boarding pass.

• Navi Mumbai airport (NMI) has flown international routes since July 2026, but only to the Gulf. No international flight from NMI connects to Siem Reap yet.

• Pune travellers have routings through Bangkok and Kolkata too, but Mumbai T2, 3 to 4 hours by road, offers far more departure times.

• Carry about US$100 in small notes for the visa, shuttle and first meals. ATMs at SAI and in town dispense dollars.

• Keep your e-visa approval and CeA QR code on your phone and on paper.

• Adding Vietnam? Fly into Siem Reap and out of Ho Chi Minh City, or the reverse. Our Cambodia Vietnam tour from Mumbai builds that loop.

• A package with flights from Mumbai removes the connection risk and includes the airport transfer. Compare Cambodia tour packages from Mumbai, or the 3-night Angkor Wat Cambodia package.

Plan your Siem Reap trip from Mumbai

Mumbai to Siem Reap takes one stop and most of a day. The right hub depends on what you want most: speed and frequency through Bangkok, the lowest rupee fare and no foreign transit through Kolkata, or a Vietnam add-on through Ho Chi Minh City. If you would rather have the flights, visa paperwork and airport pickup handled together, see our Cambodia tour packages from Mumbai.
