Washington → Taipei flights

Fares cluster near $624, but a few spikes hit $1,141

Key takeaways

• $624 median fare across the sampled days, with the middle half of fares packed tightly between $623 and $624
• Low of $623 sits almost exactly at the median — most observed fares were right around this price
• High of $1,141 shows occasional spikes nearly double the typical fare
• 83% spread reflects those rare high outliers, not everyday price swings — the bulk of fares were remarkably consistent
• Only 15 of the last 30 days had a cached fare, so treat this as a useful but partial picture

The full picture

The data shows a route with a clear anchor price: a $624 median, a $623 low, and a tight p25–p75 band of just $623 to $624. That tells us most sampled fares on this Washington–Taipei route land in a narrow $620s cluster, which is unusual for a long-haul international itinerary. When fares do move, they move sharply — the $1,141 high is nearly double the median, which is what drives the 83% spread figure. In practice, that means travelers are likely to see a steady baseline fare most of the time, punctuated by occasional expensive outliers rather than a smooth gradient of prices.

We don't have enough resolution in this sample to say when in the booking horizon those spikes occur, since the data doesn't break out how far in advance each fare was observed. What we can say is that the tight clustering near $624 suggests this may be a fairly stable base fare for the route, with the $1,141 figure likely tied to a specific date, class, or carrier combination rather than a general horizon effect. If you're pricing a trip now, anchoring your expectations to the $620s range is reasonable, while building in some buffer in case your preferred dates land on one of the pricier days.

No single carrier or day-of-week pattern is visible in this dataset, so we can't make claims about which airline or weekday tends to be cheaper. The honest caveat here is that this sample only covers 15 of the last 30 days, which is a thin slice for a route this far-flung — the consistency we're seeing could be partly a function of limited sampling rather than genuine fare stability. Treat the $624 figure as a solid reference point, but verify closer to your travel dates.
