Route Tips
- Book AirAsia flights directly on their website (airasia.com) – third-party sites often add booking fees of €5-15 that you can avoid by booking direct.
- Check both BKK (Suvarnabhumi) and DMK (Don Mueang) airports – Thai AirAsia sometimes operates cheaper flights from DMK which is closer to Bangkok’s old city.
- Budget carriers arrive at KLIA2 terminal – while slightly farther from the city than KLIA1, it has excellent budget food options and cheap transport links.
- Thai and Malaysian citizens don’t need visas – other nationalities should check visa requirements as Malaysia offers visa-free entry for many passport holders.
- Use the AirAsia X app for best deals – they release flash sales on Tuesdays and the app often has exclusive promo codes not available on the website.
- Consider flying into Sultan Abdul Aziz Shah Airport (SZB) if available – it’s closer to downtown Kuala Lumpur and some carriers operate there.
- Malaysia has no departure tax anymore – it was abolished in 2022, so the price you see is the price you pay at checkout.
