In general, airline pilots don’t give info to tower or approach/departure control because the company files that info for them. On departure the control will read the plane’s clearance and the pilots repeat it back, in case there is a change to the filed flight plan. Good pilots repeat all clearance info back, routing/altitude changes etc. In extremis, they can use ‘Wilco’ (will comply) if they are busy since communicate comes after aviate and navigate. Military ordnance deliverers typically use this when they receive directions from a Forward Air controller (FAC) because the FAC is always busy with other things.
