The chart tracks rank positions for every carrier that appears in the fetched top-five set. Rank 1 is at the top; the sharpest leadership handoff is marked in red.
The share trend focuses on carriers that actually hold the annual leadership position at least once in the series.
Only years where the annual leader differs from the previous year are included. The first observed year is excluded by design.
| Year | Prior leader | New leader | Share swing | Leader gap |
