The story
Pronto Airways began operating air services on February 1, 2006 serving Prince Albert, Points North Landing, Wollaston Lake, and La Ronge. On March 15, 2006, service was extended to Saskatoon and Stony Rapids.
In 2015, Pronto's cargo and passenger services were absorbed into those of its parent company, West Wind Aviation, effectively discontinuing the Pronto name. Pronto Airways' fleet consisted of one Beechcraft King Air and three Beechcraft 1900Cs. The King Air and two of the 1990Cs were repainted and continue to fly under the West Wind banner.
