What is the difference between Flightradar24 and FlightAware?

I use flightaware to find out information from the past like gates, aircraft used on previous flights, flight time, etc. while Flightradar to find the position of an aircraft, the inbounds and outbounds of an airport, and just for random plane spotting while I'm bored.



Excellent question! Both Flightradar24 and FlightAware are leading global flight tracking services, but they have distinct differences in their technology, data sources, features, and target audiences.

Here’s a detailed breakdown of the key differences:

1. Core Technology & Data Sources (The Biggest Difference)

  • Flightradar24: Primarily known for its network of ADS-B receivers operated by volunteers worldwide. It visually shows aircraft on a map using this data. It supplements this with data from MLAT (Multilateration) and, for areas with poor ADS-B coverage, it uses satellite-based ADS-B data (from its partnership with Aireon). Its map interface is its flagship feature.
  • FlightAware: Uses a more diverse and integrated data pipeline. While it also has a large ADS-B network (FlightFeeder), it heavily relies on data from radar networks, airline and airport direct feeds (FDP data), and government/academic sources. This often makes its data, especially for flight status (delays, cancellations, gate info), more comprehensive and reliable, particularly in ground operations and regions with poor ADS-B coverage.

2. User Interface & Experience

  • Flightradar24: Focuses on the visual, interactive map. It’s intuitive, clean, and designed for following aircraft in real-time on a globe. The 3D view is a popular feature. It feels more like a “flight tracking app” for enthusiasts.
  • FlightAware: The interface is more data-centric and “professional.” It presents information in detailed tables, lists, and schedules alongside the map. It’s designed

The position is calculated based on many different parameters and in most cases it's quite accurate, but for long flights the position can in worst cases be up to about 100 km (55 miles) off. In settings there is an option to set for how long time you want to see estimated aircraft on map.

@flightradar24. Hi James, the colored dots represent delay status: Green = on time, yellow = 15-45 min delay, red = 45+ min delay.

While it may sound shocking to some, the simple fact is that some aircraft may simply not have their transponder on, or it may be temporarily off, or they may be carrying passengers or cargo, which warrant deactivation. In addition, not all airspace activity is always relayed to FlightRadar24 at all times.

Flightradar24. Flight tracking on Flightradar24 is powered by a network of ADS-B receivers, the largest such independent network in the world. Individuals apply to host an ADS-B receiver, and once installed, this receives signals from aircraft, Chris Lomas, a Flightradar24 aviation content specialist, tells T+L.

There are a few reasons why your aircraft may not be shown. First, the aircraft may not be fitted with an ADS-B transponder, meaning it is not compatible with our receiver network. Second, if the aircraft is fitted with a Mode S transponder and not visible, it may be flying in areas with little or no MLAT coverage.

You can also track a flight via the airline's app by navigating to the Flight Status tool (you can also find this on an airline website). Though each airline has its own tracking features, they typically show the departure and arrival times, gate information, altitude, and map of where the plane is located.

Not being show on Flightaware just means they are on one of the block lists maintained by FAA and EASA. There are military encrypted transponders, that's something you can't receive locally. I've noticed i see tons of military aircraft on ADS-B Exchange but on Flight Aware they don't show up.
