How many minutes late must owners/passengers be for scheduling to be advised?

The correct answer indicates that owners or passengers need to be at least 15 minutes late for scheduling adjustments to be advised. This timeframe is typically in place to allow for timely communication and operational efficiency. If passengers arrive later than this threshold, it can disrupt the scheduling and logistics of flight operations, which are tightly coordinated to ensure smooth transitions and optimal use of resources.

Scheduling adjustments are important as they help manage any delays and communicate changes effectively to all involved parties, including crew and support staff. If the delay falls below this period, the scheduling team might still be able to accommodate the original plans, thus minimizing disruption. Overall, the 15-minute mark serves to balance flexibility in operations with the need for planning and coordination.
