Flights Bangkok to Singapore (BKK-SIN): Airlines, THB Fares | May 2026

Flights Bangkok → Singapore (BKK-SIN) — THB Fares, Airlines, Frequency

Bangkok to Singapore is one of the busiest air routes in the world — around 126 flights a week, a near-constant stream from before dawn until late at night. It is a true regional artery, carrying business travellers, weekend tourists, shoppers, students and a large share of passengers connecting onward through Singapore’s global hub.

Block time is about 2.4 hours. With this much capacity the route runs like a shuttle: a seat is almost always available on short notice, and the only real variable is price. Full-service and low-cost carriers compete head to head across the day.

Airlines on this route

Six carriers fly BKK-SIN: Thai Airways and Singapore Airlines on the full-service side, with Scoot, Thai AirAsia, Thai Vietjet and Jetstar Asia covering the low-cost end. Full-service fares include baggage and a fuller cabin; the low-cost carriers price the seat low and sell baggage, seats and meals separately. On a route this short and this frequent, the all-in cost once add-ons are counted, and the departure time, are what decide it.

THB fares

With this much frequency, BKK-SIN fares stay highly competitive and rarely spike outside major holidays. The cheapest seats are the low-cost carriers’ early-released fares — booking two to five weeks ahead usually lands a good THB price, and mid-week departures undercut weekends. When comparing, add baggage to the low-cost headline fare; on such a short hop many travellers fly cabin-baggage-only and keep the cost minimal.
