This. November was an exceptionally good month nationwide. If you look in the report, AS and VX had the highest rate of weather and ATC delays, which explains the ranking.

On a more favorable note, Alaska just reported December performance. mainline, regional and VX all were above 80% and the numbers were dramatically better than the previous year, which again is probably just due to having fewer “snowmagedden” type events. Unusually, it would appear VX reported its best ontime performance all year in December!
