What alternative flights must a large carrier consider after a covered controllable Canadian disruption?
For the APPR’s applicable within-control branches, a large carrier must move through a sequence of confirmed alternatives rather than indefinitely offering only its next convenient flight. The sequence uses the original departure time and can expand from its own or partner service to other carriers and nearby airports.

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 covered within-control rebooking branch, a large carrier first seeks its own or a commercial partner’s next available flight departing within 9 hours of the original departure time.
- If that cannot be provided, the rule expands to any carrier on a reasonable route departing within 48 hours of the original departure; if necessary, the nearby-airport branch and transfer transport follow.
- The required alternative is a confirmed reservation without additional charge; the small-carrier branch and outside-control branch have different wording.
Important exceptions
- These steps are not the outside-control weather sequence. Available seats and reasonable routes still matter; the article does not promise a specific flight. A small carrier operating on behalf of a large carrier can have large-carrier obligations, which requires the commercial relationship to be established.
