FLPLN amendments by Pilots while airborne

[AerocatS2A]

We can do that in Australia. It depends on controller workload though.

Edit: Actually you can change pretty much anything for your active plan, request direct to a waypoint, tracking via a different route etc. That stuff won’t always be approved though. You can also ask nicely and have the controller make amendments to a later plan, that is what depends on controller workload.
