Flightradar24 vs. FlightAware: data sources, features and subscriptions compared

You’re standing at the fence, phone in hand, wondering what is emerging from the haze on final approach. Some people open Flightradar24 by reflex, others swear by FlightAware. Both show aircraft on a map, both are free to use, both sell subscriptions. Still, they feel surprisingly different in everyday use. This Flightradar24 vs. FlightAware comparison shows you where the data comes from in each case, which features matter for plane spotters, what the subscriptions bring and when you can save your money.

The short answer

Flightradar24 thinks from the map, FlightAware from the flight. Flightradar24 is optimized to show you the airspace live and clearly: filters, playback, AR view, quick info panels. FlightAware is originally a flight status service and shines with flight plans, arrival forecasts, delays and airport pages. That’s why many people reach for Flightradar24 for a spontaneous look at the spot, and for FlightAware when planning the evening before and researching registrations. There is no clear overall winner – but there is a clear winner for each task.

Two services, two origin stories

Flightradar24 is based in Stockholm and was founded in 2006. The service grew out of a network of ADS-B receivers run by volunteers – accordingly, the live position of aircraft is still the focus today. The map is the product.

FlightAware was founded in Houston in 2005 and began as a free service for public flight tracking. Its own receiver network (the Raspberry Pi software PiAware was released in 2014) and satellite data came later. Since 2021, FlightAware has belonged to Collins Aerospace, the aerospace supplier within the RTX group. You still notice that origin today: FlightAware organizes everything around flights, flight plans and airports, and the map is one tool among several.

Data sources compared head to head

Where a dot on the map comes from determines accuracy, delay and whether you see an aircraft at all. The basics of ADS-B are in the guide Flight tracking with ADS-B for spotters, and the math behind MLAT is in MLAT and multilateration explained.

Data source	Flightradar24	FlightAware
ADS-B ground stations	Main source, over 50,000 receivers according to the provider	over 30,000 receivers from users, also for ground movements at airports
MLAT	yes, needs at least four receivers and usually only works above roughly 3,000 to 10,000 ft	yes, as part of the ground network
Satellite ADS-B	yes, mainly over oceans	yes, via Aireon on the Iridium NEXT satellites
Air traffic control and radar data	Radar data from North America	Data from air traffic control in 45 countries, including oceanic position reports
ACARS/datalink	not named as a core source	Position and flight information from over 10,000 aircraft via ACARS
Airline data	Flight plan and status data are added	Airline status messages including out, off, on and in times
Other	Open Glider Network (FLARM), estimated positions	–

What does that mean in practice? In Europe, with its dense receiver coverage, both services give a very similar picture. You see differences mainly at the edges: over the Atlantic, in thinly covered regions and with aircraft with older transponders that can only be located via MLAT. FlightAware has an edge in scheduled times and status thanks to the many air traffic control and airline data sources, while Flightradar24 has very dense live coverage thanks to its large receiver network. Satellite reception is explained in more detail in the article Satellite ADS-B explained.

Features that matter for spotters

Not all features are equally important for plane spotters. Five tools are decisive: map and filters, registration search, airport view, history and alerts.

Feature	Flightradar24	FlightAware
Live map	very intuitive, the product’s focus	solid, but more of a complement to flight pages
Filters	Categories plus custom filters by airline, type, registration, route; wildcards such as “D-*”	less central, focus on search and bookmarks
Registration search	Search and filter by registration	Search by flight identifier or registration with the aircraft’s history
Airport view	Arrivals, departures, weather at the airport	detailed airport pages with status and delays
Playback	individual flights, on the website also Global Playback	History of individual flights via the flight pages
Alerts	in the paid tiers	Alerts for departure, arrival, delay and cancellation; extended with Premium
AR view	yes, point the camera at the aircraft	not a core feature

At the fence: Flightradar24 is faster

If you want to know what is approaching the runway right now, Flightradar24 is hard to beat. You open the app, zoom in on your airport and see the approach chain. One tap shows type, registration, route and usually a photo. With custom filters you highlight, for example, all widebodies or only certain airlines instead of having a map full of regional jets. How that works in detail is in the Flightradar24 guide. And if the symbols puzzle you, Flight tracker symbols and colors explained helps.

The evening before: FlightAware plans better

FlightAware plays to its strengths one step earlier. You search for a specific registration and see which routes the aircraft has flown in recent days – ideal for estimating whether a special aircraft will show up at your airport again the next day. The airport pages list arrivals and departures with scheduled and forecast times. How to use it is explained in the FlightAware guide, and the research techniques behind it in Looking up an aircraft’s flight history and Tracking an aircraft by registration.

How reliable arrival forecasts really are and how much buffer you should allow is described in How accurate is the arrival time on the flight tracker?.

Free version and subscriptions

Both services work on the freemium principle: the basic features are free, extras cost money. Concrete prices change regularly and depend on platform, country and term – so check directly in the store or on the provider’s website.

Criterion	Flightradar24	FlightAware
Free version	Live map, flight details, airport boards, ads	Flight search, status, airport pages, map; more frequent updates with an account
Free history	7 days	7 days
Subscription tiers	Silver, Gold, Business	several premium tiers
History with subscription	90 days (Silver), 365 days (Gold), 3 years (Business)	3, 5 or 8 months depending on tier
Alerts	from Silver	extended alerts in Premium
Target group of the top tier	Business: commercial use, fleet view	Enterprise: free for feeders

At Flightradar24, Silver is the most sensible tier for most spotters: longer history, alerts and additional aircraft data. Gold is worth it if you really use weather layers, airspace boundaries or extended Mode S data. The details are broken down in the article Flightradar24 subscription: what’s worth it for spotters?. At FlightAware, history is the main reason for a subscription – anyone who regularly researches registration histories over months benefits most.

The feeder route: both subscriptions without a subscription fee

Here lies perhaps the biggest lever of the whole comparison. Both services live off volunteers who supply data with their own receivers – and both reward that.

• FlightAware: According to FlightAware, anyone who shares data automatically gets a free upgrade to an Enterprise account, which the provider values at $99.95 per month. What features the account includes in detail is shown in FlightAware’s subscription overview. FlightAware puts the hardware – Raspberry Pi, USB receiver, antenna – at under $100 or €80. For suitable locations, FlightAware also provides a FlightFeeder free of charge on request.
• Flightradar24: Operators of an active station receive an upgraded account without a subscription fee for as long as the receiver is online and sharing data. For a long time it was called the Business subscription; current support texts refer to a Contributor Plan.

The nice thing: you don’t have to choose. A single receiver can supply both networks in parallel. Typical is PiAware as the base and fr24feed as an additional feeder on the same data stream. You’ll find step-by-step instructions in Setting up PiAware and Setting up fr24feed, and the hardware part in Building your own ADS-B receiver. If you want to feed even more networks at the same time, see Feeding multiple networks with Ultrafeeder. What other services offer feeders is compared in What feeders get in return.

Visibility: who shows what?

A common reason spotters switch between services: an aircraft is missing on one map and shows up on the other. There are three typical causes.

1. Coverage: Each service sees only what its receivers and data partners deliver. In border regions or with low-flying aircraft, one service may have a station in range while the other doesn’t.
2. MLAT limits: Aircraft without ADS-B position data are only located if enough stations hear them at the same time. At low altitude that often doesn’t work.
3. Blocks: Both commercial services respect blocking requests from owners. According to its FAQ, FlightAware shows details of blocked aircraft only to owners or operators.

For military, government and business aircraft, many spotters therefore also turn to services with data that is as unfiltered as possible – more on that in ADS-B Exchange explained, Community trackers compared and Tracking military aircraft online. The general reasons for missing aircraft are summarized in Why an aircraft doesn’t show up on Flightradar.

How to combine both in your spotting routine

In practice, the two services complement each other better than they compete. A proven routine for a spotting day, for example at the Zeppelinheim viewing platform at Frankfurt Airport or at the Munich Airport visitors’ hill (Besucherhügel):

Setting up alerts on both services is described in Setting up notifications for aircraft, types and airlines. For step 4, Matching sightings with ADS-B logs helps.

What to watch out for

• Forecasts are forecasts. Arrival times and positions are estimates with a delay. Always allow a few minutes of buffer.
• Subscriptions renew automatically. Trial periods often end in an extended subscription if you don’t cancel in time – on the App Store and Google Play you manage this in the store settings.
• The map is no substitute for looking up. Especially with low-altitude movements, helicopters or light aircraft, data is missing more often. Your ears and eyes remain your fastest sensor.
• Photos and data are not free to use. Map sections and aircraft photos from the apps are subject to the services’ terms of use and the photographers’ copyright.

If you want to look beyond the two big players, the Flight tracker app comparison has more services such as Plane Finder and RadarBox, and Free flight trackers lists the best free options. Which apps beyond that belong in a spotter’s basic kit is shown in the Plane spotting app comparison.

Conclusion

Flightradar24 and FlightAware draw on similar types of data, but set different priorities. Flightradar24 is the better live map with strong filters and playback – ideal for the moment at the fence. FlightAware is the better flight plan and status service with broad integration of air traffic control and airline data – ideal for planning and research. The free versions of both services are enough for many spotters. If you want more history and alerts, check the feeder route before buying a subscription: a receiver of your own unlocks upgraded accounts on both services.
