Historical disruption is high; strong buffer and protection options are advisable. This route appears in the elevated-risk subset across 11 distinct months, with 772 observed operations and a weighted cancellation rate of 15.0%. The volatility profile (7.9%) indicates how unevenly cancellations cluster month to month rather than assuming a flat yearly average. Tier model v1 computes an adjusted route risk of 19.0%. Use this as route context, not deterministic prediction.
