It seems that whenever inputting a route in either the 747 or 787 in MSFS, for example:
KJFK to EGLL
I want to begin on the J79 airway up to LFV, so I input LFV to LSK1R on the Routes page, and the J79 airway automatically appears.
HOWEVER, it seems to directly take me to LFV and NOT along the airway, and also misses out on CRAIL, HOFFI, CUTOX etc. (other waypoints on the airway).
This seems to be the case for ALL airways, and I was wondering if this is a sim issue or if I’m doing something wrong when inputting the route in the FMC?
