Vaughan,
the planned route was KPWT, KSEA, 95WA loaded as FSX flight plan.
After departing and being handled by the KPWT Tower voxatc told me "fly the flight plan". There were no options in the enroute menu until reaching 95WA ("contact Destination"). Alt 2.500 ft.
Voxatc did not recognize KSEA control zones.
