Nearby airports are included by default, so a Bangkok search returns both Suvarnabhumi and Don Mueang departures — you don't need to search them separately. Flying midweek (Tuesday–Thursday) typically saves 10–25% compared to weekend departures. Being flexible with your dates can save you hundreds more. Book 2–4 months ahead for peak season, or 1–2 months for off-peak travel.
