Scheduled means the last change to status was more than 3 hours ago.
So normally the plane had not left when they posted the times.
En Route means that the plane is in the air on way to destination & the last change to status less than 3 hours ago. More often than not a matter of minutes since last update.
En Route is a more reliable indication of arrival time than Scheduled.
