Flight notes

Flight tracking, alerts, and travel data—explained.

Practical explanations of flight data, monitoring, trip coordination, and what FlightDan is learning along the way.

Why we built FlightDan

Flight tracking has plenty of data. The harder problem is knowing which changes deserve your attention.

A flight six months away and a flight boarding now should not be checked on the same schedule.

Scheduled, estimated, actual, and provider-derived times describe different parts of the same flight.
