Los Angeles → London flights
Fares on Los Angeles–London averaged $307 across 30 daily snapshots, with a wide $216–$371 range; booking during softer demand windows can push you toward the $216–$303 floor.
LAX–LHR median hits $307 — the bottom quartile starts at $303
Key takeaways
- Median fare is $307, drawn from 30 daily snapshots of the cheapest available cached fares.
- The bottom quartile (p25) sits at $303 — only $4 below median — meaning truly cheap fares below that level are uncommon but not impossible.
- The floor of $216 represents the single best observed price; the ceiling of $371 shows the spread is wide at 72%, so timing genuinely matters on this route.
- The interquartile range ($303–$319) is notably tight, suggesting that on most days the cheapest available fare clusters within a $16 band around the median.
- With such a compressed IQR, outlier low fares near $216 are rare events — likely flash sales or error fares — rather than a dependable booking pattern.

The full picture
The LAX–LHR price picture is an interesting mix of tight typical fares and a surprisingly wide outer range. On a day-to-day basis, the cheapest available fare clusters between $303 and $319 — a remarkably narrow $16 interquartile range for a roughly 5,500-mile transatlantic route. That compression tells you that competition among carriers on this corridor (one of the world's busiest) keeps most days priced similarly. The median of $307 is a reasonable planning anchor: budget around that figure and you won't be far off on the majority of booking days.
Where it gets interesting is the outer edges. The observed low of $216 is 30% below the median — a significant gap that points to genuine opportunistic pricing rather than routine fare movement. These sub-$250 fares do appear in the 30-day window, but they're below the 25th percentile, meaning they showed up on fewer than a quarter of sampled days. The practical implication: if you're flexible and can monitor fares over a few weeks rather than booking the moment your trip is confirmed, you improve your odds of landing something closer to that floor. Setting a fare alert at or below $280 gives you a realistic trigger that's above the floor (so it'll actually fire) but meaningfully below the typical range.
On booking horizon, the data doesn't include departure-date metadata, so we can't pinpoint whether fares soften at 6 weeks out versus 10 weeks out with precision. What the spread percentage of 72% does confirm is that the gap between the worst and best available price is large enough to reward patience. Carrier patterns are similarly not resolvable from this dataset alone. One honest caveat: a 30-snapshot sample captures one rolling window in time — seasonal demand shifts, fuel surcharge changes, or a new fare war could move the entire distribution up or down materially. Treat $307 as today's baseline, not a permanent benchmark.
