San Francisco → Singapore flights

SFO–SIN median is $367 — budget $355–381 for a solid deal

Key takeaways

• $367 is the median one-way fare across 30 daily snapshots — a reliable anchor for budgeting.
• The interquartile range runs $355–$381, meaning half of all observed fares fell within a tight $26 band.
• The floor was $342 and the ceiling $405 — an 18% spread that signals moderate but not extreme volatility.
• Fares below $355 (p25) represent genuine bottom-quartile pricing; anything under $350 is meaningfully below trend.
• The 18% spread is modest for a transpacific route, suggesting this market is relatively stable rather than prone to sharp swings.

The full picture

San Francisco to Singapore is a roughly 17-hour transpacific haul, and the 30-day fare snapshot paints a surprisingly stable picture. The median of $367 sits almost exactly midway between the observed low ($342) and high ($405), which tells you the distribution isn't heavily skewed — you're not chasing rare flash sales at one end or bracing for sudden spikes at the other. An 18% spread is moderate for a long-haul international route; for context, routes with high seasonal demand or thin competition often run 30–50% spreads. That compression here suggests the SFO–SIN market has reasonably consistent supply, likely supported by multiple carriers operating the corridor.

For booking strategy, the interquartile range ($355–$381) is your practical target zone. If you see a fare at or below $355, that's a bottom-quartile price worth acting on — you're unlikely to do meaningfully better without getting lucky. Fares above $381 put you in the top half of what this 30-day window recorded, so it's worth a short wait or a flexible-date search before committing. The absolute floor of $342 appeared, but treating it as an expectation rather than an occasional data point would be overconfident given the sample.

Day-of-week departure patterns and carrier-specific pricing are not directly visible in this dataset, so any claims there would be speculation. What the data does support: this is not a route where waiting indefinitely for a dramatic price collapse is well-justified — the $63 gap between low and high means the upside of patience is real but limited. One honest caveat: 30 snapshots capture a single rolling window and may not reflect seasonal demand shifts, such as Lunar New Year travel or school holiday surges, that could temporarily push fares well outside this range.
