An airline filed the following flight plan:
[...] IRK.J96.SLN..LANCY.J134.PKE [...]
The cruise altitude was around 30k feet.
Waypoints in J96 are:
LAX PDZ YCDIL PKE* LANCY* DRK KEYKE GUP CIM GCK SLN* AGENT KIDER IRK* NORIS PIA JOT
J96 spans between 18k-45k feet.
So it means that someone put a direct in the middle of an airway. Why was the flight plan not filed with an all-airway routing like this:
[...] IRK.J96.LANCY.J134.PKE [...]
Is it common practice to omit some points in an airway?
