San Francisco → Bangkok flights

Budget $424 for SFO–BKK — floor sits near $354

Key takeaways

• Median fare is $424 across 30 daily snapshots of the cheapest available cached fares.
• Bottom quartile fares (p25) start at $419 — meaning the gap between median and a 'good' fare is surprisingly thin, suggesting prices cluster tightly around $420.
• The absolute low recorded was $354, roughly 17% below median — achievable but not the norm.
• Spread of 39% between low ($354) and high ($493) indicates meaningful volatility; timing your search can matter by $100+.
• Top quartile (p75) reaches $482, so fares above ~$480 are in expensive territory — a useful ceiling to walk away from.

The full picture

San Francisco to Bangkok is a long-haul transpacific route where fares in this dataset ranged from $354 to $493, with a median of $424. The relatively tight interquartile range — from $419 at p25 to $482 at p75 — tells an interesting story: most days, the cheapest available fare is hovering close to $420. That means genuine bargains below $400 are uncommon, and when they appear they tend to be brief. The $354 floor exists in the data, but don't build your travel budget around hitting it.

With a spread of 39%, there is enough price movement across the 30-day window to reward patient, flexible shoppers. On this corridor, fares historically soften when airlines are trying to fill remaining seats on routes with multiple connecting options through hubs like Tokyo, Seoul, or Taipei. Searching 6–10 weeks ahead of your intended travel date typically captures fares in the lower half of this range, while last-minute searches (under two weeks out) are more likely to push you toward the $480–$493 zone. No dominant carrier signal was present in this dataset, so comparison-shopping across available airlines on this route is especially worthwhile — connection routing can swing prices noticeably even at the same headline fare level.

One honest caveat: 30 snapshots reflect cached cheapest fares at the moment each query was made, not a full picture of all inventory or all departure dates. Seasonal demand — particularly around Thai holidays, Songkran in April, and peak Western travel periods — can push prices well outside this observed range. If your travel window falls near any major holiday, treat the $493 high as a floor rather than a ceiling and search accordingly.
