This happens if you have 2 or more ai traffic files (traffic*.bgl) that have identical flight plans.
For example, there are a few ai traffic packages (ai aircraft plus ai traffic files) that are built by using the default traffic file flight plans flying substitute ai aircraft. A few that come to mind are Chesters International AI and the Continental AI and European AI packages. Using even 1 of these packages, along with the default ai, will result in duplicate schedules.
The solution is to identify the traffic files that are duplicating flight plans and removing or disableing one of the files.
A way to avoid this is to add ai packages that are built using 'custom' flight plans. For ai airlines, packages from WOAI or PAI are built on real world schedules, so the chance of duplicate flight plans should be minimal.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
