Fare Index
One number for the whole world: how today’s fares compare with their own history. 0 means everything is at its most expensive ever, 100 means everything is at its cheapest ever. Above 58 is a good week to book.
Today the Fare Index is 54, computed from 42881 routes we watch, on prices as of 2026-11-07.

How it is computed
For every route we watch, we know where today’s cheapest fare sits inside that route’s own 90-day price history — its percentile. The Fare Index is 100 minus the median of those percentiles. We use the median, not the average, so a handful of broken or freak prices cannot move it; we only count routes whose verdict we trust; and we publish the number of routes behind every number. Because each route is compared only with itself, countries with expensive flights and countries with cheap flights are directly comparable.
