Looking for cheap flights from Delhi to Siem Reap? FlightGPT compares live DEL to REP 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 Delhi to Siem Reap non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Delhi-Siem Reap fare is one search away.
There is no scheduled non-stop Delhi–Siem Reap flight; all options are one-stop. The most common routings go via Bangkok (Thai Airways, Bangkok Airways, Thai AirAsia), Singapore (Singapore Airlines) or Kuala Lumpur (AirAsia, Malaysia Airlines), often with Cambodia Angkor Air or regional partners on the final hop. Bangkok is the classic, shortest connection given its proximity to Cambodia.
A well-timed one-stop runs about 8–9 hours total; longer layovers can stretch it past 11 hours. Bangkok offers the shortest final leg into Siem Reap; Singapore and Kuala Lumpur are slightly longer but well served. The Delhi–hub sector is the long part of the trip, with a short regional flight completing the journey.
Cambodia's cool, dry season (November–February) is the most comfortable for temple-hopping and the busiest for fares; the hot months (March–May) and the green wet season (June–October) are quieter and often cheaper. October can be a good-value shoulder month. Book a few weeks ahead and stay flexible — compare the live fare calendar in the FlightGPT search.
As a connecting route, flexibility on dates and hub choice saves the most. Compare a Bangkok routing against Singapore and Kuala Lumpur, and consider booking the long Delhi–hub leg with a separate regional hop if it's cheaper. Mid-week travel and booking ahead help, and the wet/shoulder months are gentler on price. Use the FlightGPT search to line up all routings together.
Departures use Delhi Indira Gandhi International (DEL) Terminal 3. Siem Reap is now served by the new Siem Reap–Angkor International Airport, opened to protect the nearby temples from low-flying traffic; it sits farther from town than the old airport (about 40–50 km), so arrange transfers in advance. Confirm your hub's minimum connection time on the outbound leg.
Allowances depend on the carrier and fare. Full-service airlines (Thai, Singapore Airlines, Malaysia Airlines, Bangkok Airways) usually include a checked allowance, while budget carriers like AirAsia sell it as an add-on. When your itinerary combines a long-haul leg and a regional hop, check each booking's allowance separately and confirm whether your bags are through-checked to Siem Reap.
Indian passport holders need a visa, but it's straightforward. The Cambodia e-visa (tourist 'T' class) costs about USD 36 in total and is applied for online at evisa.gov.kh, valid for a 30-day stay, usually issued in about three business days. A visa-on-arrival (about USD 30, cash in US dollars only) is also available at Siem Reap and Phnom Penh airports. Carry a passport valid 6+ months with blank pages.
Bangkok is the natural gateway to Cambodia — closest, with the shortest final hop and many frequencies. Singapore offers a premium hub with reliable connections, and Kuala Lumpur adds budget-friendly AirAsia options. Each pairs a long Delhi–hub leg with a short regional flight to Siem Reap; choose by fare, schedule and layover length.
Cambodia widely uses US dollars alongside the riel; carry small-denomination USD cash. Buy an Angkor Archaeological Park pass (1-, 3- or 7-day) and start at sunrise for the best light and fewer crowds. Dress modestly at temples (shoulders and knees covered). Tuk-tuks are the easy local transport. The dry season is hot — bring sun protection and water. Engage a licensed guide to bring Angkor's history to life.
Siem Reap is the base for one of the world's greatest archaeological wonders — the vast temple city of Angkor. Watch sunrise over Angkor Wat, explore the tree-strangled ruins of Ta Prohm, and marvel at the stone faces of the Bayon. Beyond the temples, the town offers floating villages on Tonlé Sap lake, lively night markets and warm Khmer hospitality, making it a bucket-list trip from India.
