Looking for cheap flights from Bengaluru to Siem Reap? FlightGPT compares live BLR to REP fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side.

Siem Reap has no direct link to Bengaluru, so you will connect through a regional hub. Bangkok is the most common, with Bangkok Airways and AirAsia flying onward to Siem Reap; Singapore and Kuala Lumpur are alternatives, and Cambodia Angkor Air serves some regional legs. From Bengaluru, IndiGo, Air India and Singapore-bound carriers feed these hubs. A single low-cost itinerary (for example Bengaluru–Bangkok, then AirAsia or Bangkok Airways onward) is often cheapest, while a through-ticket on one carrier smooths baggage and transfers. Compare both styles on FlightGPT — indicative fares are live (fares as of May 2026); always verify live schedules.
Siem Reap's cooler, drier peak runs roughly November to February, when Angkor demand and fares rise; the May–October green season usually brings the lowest prices with afternoon rain. For Indian travellers, mid-week departures and avoiding Diwali and the December–January peak tend to save the most. Booking around 6–10 weeks ahead is a sensible sweet spot on a 1-stop itinerary, and being flexible on the connecting hub often unlocks cheaper combinations. Set a price alert and compare live options on FlightGPT → indicative fares are shown (fares as of May 2026); always confirm current schedules.
Total travel time is typically ≈ 8–10 hours with one stop, and longer if the layover is wide. The Bengaluru–hub leg runs roughly 3.5–4.5 hours (to Bangkok), followed by a short 1–1.5 hour flight onward to Siem Reap. Siem Reap (UTC+7) is 1 hour 30 minutes ahead of IST, so a morning Bengaluru departure can land the same evening. With no non-stop option, keep a comfortable connection buffer, especially on separate tickets where you self-transfer your bags. Always verify live schedules and minimum connection times on the operating airlines' sites before committing.
Baggage is the key thing to check on hub itineraries. AirAsia and similar budget carriers sell cabin-only base fares, so checked bags are paid add-ons on each leg, and a self-transfer at the hub means re-checking luggage. Bangkok Airways is more generous and typically includes checked baggage plus lounge access even on shorter fares. Always add bag fees to the headline price before comparing, and weigh any saving against transfer hassle on separate tickets. FlightGPT shows indicative fares (fares as of May 2026); confirm exact allowances and charges on each operating airline's official website.
You depart Kempegowda International Airport (BLR) from Terminal 2 for international flights. Your connection happens at the hub — at Bangkok, low-cost flights often use Don Mueang (DMK) while full-service use Suvarnabhumi (BKK), so a mixed itinerary may need an inter-airport transfer; plan for it. You arrive at the new Siem Reap-Angkor International Airport (code SAI, still widely listed as REP), opened in 2023 and located about 40–50 km from the town and temples, with taxis and shuttles into Siem Reap.

Carry your printed e-visa or visa-on-arrival paperwork, proof of onward travel and accommodation, as these may be checked.
