In exchange for sharing data, Flightradar24 gives you a Business Plan subscription for free (a $499/year value). The Catch: You must keep your receiver online 24/7. 2. The 7-Day Free Trial

Access up to 365 days of past flight data.

Overlay rain, lightning, and wind clouds onto your tracking map.

Flightradar24 relies on a global network of volunteers who host ADS-B receivers. If you live in an area where coverage is needed, the company will often send you the hardware for free. If you build your own receiver using a Raspberry Pi, you can feed data to their network.

If you only need Gold features for a specific trip or event, the official free trial is your safest bet. Sign up via the website or mobile app. You get full access to all Gold features for 7 days.
