What does IROP refer to in airline operations?

• A. Irregular Operations (such as a weather event)
• B. International Route Optimization Program
• C. In-Route Onboard Pacing
• D. Immediate Ramp Operations Procedure

Answer: (A)

IROP stands for Irregular Operations, the term used to describe disruptions that affect the normal flight schedule. When events like severe weather, equipment issues, or airspace restrictions occur, operations shift into IROP mode to manage the impact safely and efficiently. This involves coordinated actions such as rebooking or re-accommodating passengers, communicating updates to customers and crew, arranging accommodations or meals as needed, adjusting gate and crew assignments, and implementing contingency plans to minimize delays and keep operations moving. The idea is to switch from executing a planned schedule to actively solving problems and keeping everyone informed during disruptions. The other options describe terms that aren’t standard in this context and don’t capture the disruption-management focus of IROP.
