Why is my Expected Route notification different from my actual route received by ATC?

We provide Expected Route notifications when we receive them from the ATC systems.  These routes are what the system expects your verbal IFR clearance to be issued as, but can be changed by the clearance controller. A typical change would be to require flying the departure procedure currently in use.

If this expected route matches what the route you filed then it is expected (but not guaranteed) that the controller will issue your clearance "as filed".
