The interpretation of this rule has been if the &#039;scheduled&#039; run time of both segments (not &#039;actual&#039; run time) is less than three hours AND if there is more than one hour turnaround (interval of release), then eight for nine applies.<br /><br />Example 1, schedules through 4/24/16:<br /><br />351 DEP BTL 9:01 AM ARV CHI 10:46 AM - 2 HR, 45 MIN OD CHI 10:56 AM<br />352 DEP CHI 12:50 PM ARV BTL 440 PM - 2 HR, 50 MIN OD CHI 12:00<br /><br />Both segments are scheduled to run less than three hours AND the turnaround time is just OVER one hour so eight for nine would apply under the current interpretation. If instead of 10:56 AM the off duty time, for whatever reason, is 11:01 AM, the turnaround is now LESS than one hour and eight for nine would NOT apply.<br /><br />Example 2, schedules through 4/24/16:<br /><br />365 DEP BTL 9:52 AM ARV CHI 11:45 AM - 2 HR, 53 MIN OD CHI 11:55 AM<br />354 DEP CHI 6:00 PM ARV BTL 9:47 PM - 2 HR, 47 MIN OD CHI 5:10 PM<br /><br />Both segments are scheduled to run less than three hours and the turnaround time is 5 HR, 15 MIN so eight for nine would typically apply.
