A number from 0 to 100 built on our own price history: how far below the usual the deal sits on that route (55%), the arrival and return times (25%) and how comfortable the trip is (20%). It only shows up once a route has enough history.

Tap a flight above: it opens just like in the app, with the map, times, Flappy Score and price history.

When a flight appears under your maximum price you get an email and, if you install FlyDown as an app from your browser, a notification too. Straight away or in a daily digest, with your own quiet hours.
