Over the last 30 days, IAH–Istanbul fares showed a median of $400, with the middle half of all observed prices landing in a narrow $384–$408 band. That tightness is the headline story here: a 31% spread between the $355 low and $465 high sounds wide, but the bulk of fares clustered close to the median, meaning most travelers who checked on a given day saw something close to $400 rather than a wild swing in either direction.
Because the data covers a full 30-day window with a fare recorded every day, we can be confident this isn't a thin or sporadic sample. That said, the data doesn't tell us where in the booking horizon the $355 low or $465 high occurred — we only know the range existed somewhere in this window. If you're watching this route, treat $400 as your benchmark: anything comfortably under that, especially down toward the $384 p25 mark, is a solid fare worth booking rather than waiting on, since the data gives no evidence that waiting further out would meaningfully beat it.
We don't have visibility into day-of-week patterns or a dominant carrier for this route, so we can't make claims about specific departure days or airline-specific pricing behavior. The honest takeaway is that this is a fairly stable route price-wise — a 31% spread with most fares bunched near $400 suggests moderate but not extreme variability, so booking decisions here should hinge more on your travel dates and itinerary needs than on chasing a theoretical rock-bottom fare that the data doesn't strongly support.
Why we regenerated this article: Price spread widened by 19 points. We only rewrite when the underlying price index actually moves — stable weeks keep the previous take.
