Dialectal Variation
British vs American Usage

Connotations
In both, it connotes officialdom, quality, or a signal. In the US, due to the flower and historical use of blue flags in railroads, it may have slightly more diverse technical associations.
Frequency
Similar overall frequency, with spikes in coastal/ environmental and motorsport commentary contexts.
