How to find cheap tickets

1. Book three months ahead — Skyscanner’s data suggests this timing offers the best deals for SIN‑BKK (Skyscanner travel search engine).
2. Consider Don Mueang (DMK) — flying into Bangkok’s secondary airport can reportedly reduce fares; Skyscanner advises booking three weeks before arrival at DMK to avoid price surges.
3. Fly late morning — about 22% of passengers prefer the 9am‑noon window, which often has more seat availability (Expedia travel booking platform).
4. Compare low‑cost vs full‑service — a no‑frills fare might save you 40–50% versus a premium carrier, but factor in baggage and meal costs.

The catch: exact fare availability changes daily. Set a price alert on Skyscanner or Google Flights a few months out.

How to book a cheap flight from Singapore to Bangkok – Step by step

1. Start comparing 3 months before your trip. Skyscanner’s internal data indicates that 90 days out is the sweet spot for SIN‑BKK fares (Skyscanner travel search engine).
2. Decide on your airport. BKK (Suvarnabhumi) is the main hub, but if you’re flexible, check flights to DMK (Don Mueang) – budget carriers sometimes offer cheaper tickets there.
3. Choose your departure time. Late‑morning departures (9am–noon) have the most options and are preferred by 22% of travelers (Expedia travel booking platform).
4. Compare total cost, not just base fare. A SGD 190 Scoot ticket may become SGD 250 after adding 20 kg checked baggage. Singapore Airlines’ lowest fare already includes 25 kg.
