Whether or not these stats are meaningful regardless of this is still open for debate, but these do include all delays longer than 15 minutes regardless of the cause. If you were to remove delays that the DOT considers to be outside the airlines' control (weather, etc.), UA's on-time percentage would shoot up to close to 90% (as would everyone else's).
