How we observe flight prices

Every fare on a route page is a real observation with a check date. This is how it gets there.

Where the prices come from

Wildly reads fares from Google Flights. We do not model, estimate or extrapolate the numbers shown in the “Lowest fare in our latest check” section of a route page or in the live-fare lists on origin hubs. If a route has no observation, that section is not shown.

How often

Each tracked route is checked once a day. The check time is stored with the fare and printed next to it (for example “checked Sep 29”). A fare older than 7 days, or for a month that has already passed, is no longer shown as current.

The sample trip

A daily check prices one representative itinerary: a round trip of seven nights in the travel month shown, economy, one adult. We record the lowest fare Google Flights returns for that itinerary, the operating carrier, the number of stops, and the departure and return dates sampled. The dates are shown on the page so you can judge how close the sample is to your own trip.

Price bands

Where a route page labels a fare as typical, good or great, the bands are percentiles of the fares we have observed on that route, not targets we chose. A route with only a few days of history has wide, uncertain bands; the page says how many observations sit behind them. Bands tighten as the daily series grows.

Estimates are labelled

Some hub and filter pages still show figures marked “estimated” or “modelled”. Those are distance-based planning figures, not observations, and they never appear in structured data as offers. We are replacing them with observed data route by route.

Limitations

Use the data

Today's observed fares for every route are published as a table at wildly.ai/fares.md and as JSON at wildly.ai/fares.json, each with the date it was checked. You are welcome to quote them with attribution: name Wildly and link the route page. Site owners can also embed a route's fare.

Corrections

If a number on Wildly looks wrong, write to [email protected] with the page URL. We check the underlying observation and fix or annotate the page. More about who runs the site is on the about page.
