FSLTL Set to Lose FlightRadar24 Live Traffic Feed on April 30

There's some tough news breaking across the Microsoft Flight Simulator community this week, especially for virtual pilots who rely on realistic live traffic to bring their skies to life.




FSLTL, one of the most popular freeware traffic solutions for MSFS, has confirmed that the FlightRadar24 data feed it uses for real-time live traffic injection will be shut down on or before April 30, 2026. That means the current system that helps populate the sim with real-world aircraft movements will soon be grounded unless a new data provider can be found.




According to statements shared by the FSLTL team, the issue comes down to cost. While there had been hope for a lower-cost option that users could purchase directly through FlightRadar24, that plan never materialized. The standard pricing for the API appears to be far too expensive for practical use in a freeware tool, with estimates reportedly running higher than many simmers would be willing to pay for a single session.




Once the cutoff happens, FSLTL says it will release a version of its injector that removes the current FlightRadar24 API calls. In plain English, that means the injector will likely continue only as a static aircraft injection tool, rather than a live real-time traffic solution.




The good news is that this does not affect the FSLTL Base Models package. The aircraft models, liveries, and related updates are expected to continue, so the project itself is not disappearing overnight. Still, this is a major blow for simmers who have come to depend on FSLTL for one of the most immersive freeware traffic experiences in MSFS.




FSLTL says it is actively searching for alternatives, but the road ahead is uncertain. The team outlined several possible outcomes, including finding another free provider, working with a lower-cost partner, remaining static-only, or in the worst-case scenario, ending the injector entirely.




To their credit, the FSLTL developers made it clear they do not blame FlightRadar24 for the decision. FlightRadar24 is a commercial business, and maintaining access to live aviation data comes with real costs. Still, for the flight sim community, this marks the end of an era unless a new solution can be found.




For now, simmers who value live traffic immersion will be watching closely to see what happens next. One thing is certain: the skies over Microsoft Flight Simulator may feel a little quieter after April 30.
