What is the deadline to submit an irregularity report after the end of pairing?

• A. 24 hours after end of pairing
• B. 48 hours after end of pairing
• C. Immediately after event
• D. Within 72 hours after end of pairing

Answer: (A)

Timing matters when reporting irregularities. The deadline is within 24 hours after the end of your pairing. This end-of-pairing moment marks when your duty for that assignment finishes, and it’s the reference point for submitting the report. Submitting within a day helps you capture what happened while details are fresh and ensures safety teams can review and act promptly. If you wait longer, memory can fade and important specifics may be lost, delaying investigation and corrective actions. The other timeframes extend beyond the allowed window or anchor the report to the event itself rather than to the end of the pairing, which isn’t how the process is designed.
