Airlines on this route

Three low-cost carriers fly DMK-SIN: Thai AirAsia, Scoot and Jetstar Asia. All three price the base seat low and sell baggage, seat selection and meals as extras. The all-low-cost line-up keeps fares keen; on a flight of this length many travellers still fly cabin-baggage-only. When comparing, count the baggage you need into the total — it is the all-in THB cost, not the headline fare, that decides value.

About Singapore

Singapore, the destination here, is a compact, efficient city-state at the tip of the Malay Peninsula. For budget travellers it is famously not a cheap city once on the ground — but its hawker centres, free-to-enter gardens and excellent public transport make a short, well-planned visit very manageable. Reached via Changi Airport, Singapore also works as a low-cost springboard for onward travel across Southeast Asia.
