Looking for cheap flights from Bangalore to Siem Reap? FlightGPT compares live BLR to SAI fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Bangalore to Siem Reap non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Bangalore-Siem Reap fare is one search away.
There is no non-stop, so the decision is the connecting hub. Singapore usually gives the shortest total time — Singapore Airlines or its low-cost arm Scoot feed Siem Reap from a daily BLR–Singapore service. Bangkok is often the cheapest, with Thai Airways or Bangkok Airways (the "boutique airline" with the most Siem Reap frequencies) on the onward leg. Kuala Lumpur is a popular value option via AirAsia or Malaysia Airlines. For the smoothest trip, book the whole journey on a single ticket so your bags check straight through to SAI.
Cambodia's peak tourist season is the cool, dry November to February window — the most comfortable time for Angkor and the priciest for flights. The cheaper stretch is the green/rainy season, roughly June to September, when the temples are quieter and the moats are full. As of May 2026, indicative round-trip economy fares run roughly ₹28,000–48,000 depending on hub and season, with one-ways from around ₹14,000 on the keenest connecting sales. Book 6–8 weeks ahead for peak-season dates. Indicative ranges only — check live fares in the FlightGPT chat.
With no direct flight, plan for the 9–12 hour single-stop reality (the great-circle distance is only ~2,823 km, but you fly via a hub). The fastest pairing is usually BLR–Singapore (~4h 30m) onto a short Singapore–Siem Reap sector (~2h 15m); Bangkok and Kuala Lumpur routings are comparable, with the layover length the biggest variable. Siem Reap is just 1h 30m ahead of India, so the time change is gentle. A morning departure from Bengaluru can reach Siem Reap by evening on an efficient connection — check the layover carefully, as some itineraries pad in long waits.
Allowances vary by carrier and fare. Full-service options — Singapore Airlines, Thai Airways, Malaysia Airlines — typically include 25–30 kg checked plus cabin in economy, while low-cost legs on Scoot, AirAsia or similar may sell baggage as a paid add-on, so read the fare rules before booking. As always with connecting trips, mixing non-partner airlines can mean re-checking bags at the hub and the most restrictive rule applying, so a single through-ticket is the safest bet. Request vegetarian or Jain meals at booking on the full-service sectors.
Bengaluru (BLR) — international flights depart the newer Terminal 2, about 35 km north of the city. Siem Reap (SAI) — the new Siem Reap-Angkor International Airport opened in October 2023, replacing the old in-town REP airport. It sits about 50 km east of Siem Reap, built farther out to protect the Angkor monuments from aircraft vibration and pollution; allow about an hour by taxi or hotel transfer into town. The airport is modern and spacious, with visa-on-arrival counters for those who have not pre-arranged an eVisa.
Indian passport holders need a visa for Cambodia, but it is straightforward. The easiest route is the Cambodia eVisa, applied online before travel via the official portal (evisa.gov.kh) — a tourist eVisa costs around USD 36 in government fees (agents add a service charge) and is usually issued within about three business days, valid for a 30-day stay. A visa-on-arrival (around USD 30) is also available at Siem Reap-Angkor airport. You will need a passport valid six months and a passport photo. All arrivals must also complete the online Cambodia e-Arrival (CeA) registration shortly before travel. Full details are in the Visas guide.
The best time for Angkor is the cool, dry season, November to February, when days are comfortable for temple-hopping and sunrise at Angkor Wat — it is also the busiest. March to May is very hot, regularly into the high 30s°C, so start early and rest at midday. The rainy season (June–October) brings lush green, dramatic skies, full moats and far fewer crowds, with showers usually short and afternoon-bound. A three-day Angkor pass suits most visitors. For more on the area, see the Siem Reap destination guide.
