Note whether your Bangkok connection is at Suvarnabhumi (BKK) or Don Mueang (DMK), as AirAsia uses DMK. See our Siem Reap destination guide for arrival-day planning.

On international itineraries, Thai AirAsia and AirAsia base fares are usually hand-baggage-only with checked bags as a paid add-on, while Thai Airways economy typically includes around 30 kg checked. On a through-ticket the most generous allowance usually applies — confirm on your specific fare.
Pre-paid extra baggage online is far cheaper than at the counter. Seat selection, meals and priority are chargeable extras. Verify every fee on the airline's official site before booking.
You arrive at the new Siem Reap-Angkor International Airport (SAI), opened in 2023 about 40 km southeast of the city to protect the Angkor temples. Cambodia's e-visa holders use the standard lanes; an e-Arrival card is also required, completed online before arrival.
From SAI, airport taxis and pre-arranged hotel transfers reach central Siem Reap in about 45–60 minutes. For what to do on arrival, see our Siem Reap destination guide.
Indian passport holders need a visa for Cambodia. The simplest route is the Cambodia e-Visa (Type-T tourist), applied for online via the official government portal — it allows a stay of up to 30 days and is valid for entry within 90 days of issue. As of June 2026 the e-Visa fee is around US$36 including the service charge. You must also complete the Cambodia e-Arrival form online. Your passport must be valid for at least six months.
Apply only through the official portal and carry a printed copy. Rules change, so confirm the latest before booking — see our Cambodia visa guide for Indians. Official Cambodia e-Visa portal.
On international 1-stop tickets, each airline sets its own cancellation and change fees by fare type. Cheaper Thai AirAsia and AirAsia fares carry higher penalties or are non-refundable except for taxes; flexible Thai Airways fares allow changes for a smaller fee plus fare difference. Read the fare rules at booking and verify current penalties on the airline's site.
If an airline cancels a leg, you are entitled to a refund or rebook under its conditions of carriage. A single through-ticket protects your hub connection; two separate tickets put that risk on you.
