Welcome back to Illinois. I know you love it here.East of the Rockies, the "Direct destination" works really well. West of the Rockies, not so well. We have so much special-use airspace that it's far more likely you'll need to be routed.
On Tuesday, we left Elk City, OK (ELK) for St. Louis Downtown (CPS) with a flight plan that I'd filed as DIRECT and simply got:
"you're cleared to the St. Louis Downtown airport as filed. Climb and maintain 15,000 feet."
One and done. The straight-line distance was something just over 400 miles.
