San Francisco → Reykjavík flights

SFO–Reykjavik fares cluster near $409 — low spread, little to time

Key takeaways

• $409 median fare across the sampled window, with little day-to-day drama.
• Prices ranged from a low of $391 to a high of $445, a tight spread.
• At 14% spread, this is a relatively stable route — waiting for a dramatic drop isn't well supported by the data.
• The middle half of fares fell between $391 and $445, so most days priced close to the median.
• Only 16 of the last 30 days had a cached fare, so treat this as a solid but partial read on the route.

The full picture

The data shows a narrow band of fares between $391 and $445 for San Francisco to Reykjavik, with a median of $409. A 14% spread is on the low end for international routes, meaning there isn't much volatility to exploit — the difference between a lucky day and an unlucky one is roughly $50, not hundreds of dollars. If your goal is to avoid overpaying, the practical takeaway is that most days in this window already land close to fair value.

Because the spread is tight, we can't point to a clear window where prices reliably soften — the kind of pattern you'd see on routes with wider swings between early and late booking. What we can say is that fares at or below $391 did occur on a quarter of sampled days, so patient shoppers willing to check periodically may catch the lower end of the range, but there's no strong signal that booking far in advance or at the last minute changes the outcome meaningfully here.

We don't have enough visibility into carrier mix or specific departure days in this dataset to say whether certain weekdays or airlines consistently price lower — if that pattern exists, it isn't showing up in the aggregated fares we have. The honest caveat: with only 16 of the last 30 days represented, this is a reasonably useful but incomplete snapshot. A fare on any given day could fall outside the $391–$445 band we've observed, and gaps in the data mean we're not seeing the full month's pricing behavior. Treat the $409 median as a solid benchmark for budgeting, not a guarantee.
