Singapore to Bangkok flights.

Airlines and airports

This is one of the most competitive routes in the region. Singapore Airlines and Thai Airways fly the full-service end into Suvarnabhumi, while Scoot, Jetstar Asia and AirAsia sell budget fares into both Suvarnabhumi and Don Mueang, so the route runs many daily departures across a wide fare range.

Suvarnabhumi connects to central Bangkok by the Airport Rail Link in about 30 minutes; Don Mueang has no direct metro yet and needs a road transfer of roughly 45 to 60 minutes. Pricing the Don Mueang savings against the longer transfer is the main decision on this route.

What fares look like

Outside peak windows, paid round-trip economy fares typically land between S$180 and S$380, with budget carriers filling the bottom of the band and full-service carriers the top, as of August 2026. Fares climb for the mid-year and year-end school holidays and around Songkran in April.

The cheapest consistent windows are May to June and September, between the school-holiday peaks. Because the flight is short and frequent, promotional fares appear often, and a flexible date shifts the price band noticeably.
