San Francisco → Budapest flights

SFO–BUD fares cluster near $382, with occasional spikes to $473

Key takeaways

• $382 median fare, and it's also both the low and the bottom-quartile (p25) price — meaning most observed fares sit right at this floor.
• $473 high marks the occasional spike, pushing the spread to 24% — moderate, not extreme.
• With p25 and p75 both at $382, the bulk of the 9 sampled days priced identically — there's little granular variation to chase.
• Only 9 daily snapshots here, so this read is directional, not a statistically deep sample.
• No dominant carrier was identifiable from the data, so we can't attribute the spikes to a specific airline's pricing behavior.

The full picture

The data shows a route that spends most of its time at a clear floor of $382, with sporadic jumps up to $473. That $91 gap drives a 24% spread — enough to notice, but not the kind of wild volatility that suggests chasing exact dates will pay off. Because p25, median, and p75 all land at $382, the real story isn't a gradual curve of prices but a binary pattern: you're either seeing the baseline fare or an elevated one.

With only 9 days of snapshots, we can't responsibly map out a booking-window curve (e.g., whether fares soften at 3 weeks out versus 6 weeks out). What we can say is that if you check fares and see something near $382, that's consistent with the best pricing observed in this window, and there's little evidence of a materially lower price lurking elsewhere in the data. If you see something closer to $450+, that's an outlier on the high side relative to what's typical for this route.

We don't have enough snapshots to identify a dominant carrier or a reliable day-of-week pattern for SFO–BUD, so we won't speculate on those. The honest caveat: a 9-day sample is thin for a transatlantic route like this one, and prices can shift with seasonality, fuel costs, or schedule changes that this snapshot window wouldn't capture. Treat $382 as a solid reference point for 'a good price,' but verify closer to your travel dates rather than assuming this pattern holds indefinitely.
