I submitted 3; 2 were accepted, 1 rejected for not having the Lat/Long for my ZZZZ destination inside the RZ even though it was accepted as a departure ZZZZ....???
Lots of non-standard FPL requirements, such as EETs for entry into the restricted zone which just makes it even more of a faff if you just want to go for a jolly round the block, even if you are based 35miles from the bloody venue!
Of course, we do live in a free world, so us GA pilots are not restricted in any way
