Some airports have no AFTN link. The CFMU system is available on the internet, and provides IFR flight plan information, but no VFR.
My local airport is currently assessing if it is economically viable to have an AFTN link installed. This airport is inside controlled airspace and provides tower and approach procedural ATC. The local FIR radar unit holds details of VFR plans into and out of the airport but does not normally pass on the details until the aircraft are within twenty miles inbound prior to entering the control zone.
