What should happen before a carrier selects passengers for denied boarding under the APPR’s controlled-event rules?
The reviewed APPR sets a process for seeking volunteers and, when selection remains necessary, prioritizing specified passengers. A negotiated volunteer benefit must be confirmed in writing before departure. Tell staff about a relevant priority category rather than assuming the reservation system has recognized it.

What this answer depends on
- Travel within the applicable APPR scope, including the ticketed journey and the event-specific conditions. The consolidated source displays current-through 2026-07-21; check for later changes.
- For the applicable controlled-event branches, the carrier must seek volunteers before denying boarding and must confirm an accepted volunteer benefit in writing before the flight departs.
- The boarding-priority order includes unaccompanied minors, passengers with disabilities and their specified support, travelers with family members, and passengers previously denied boarding on the same ticket.
- The carrier must not deny boarding to a passenger already onboard unless required for safety.
Important exceptions
- These process rules apply through the specified APPR branches and should not be extended uncritically to every safety or documentation refusal. Priority does not mean a guarantee that no operational problem can ever affect the passenger. Accessibility obligations can also exist outside the APPR.
