Delta Air Lines Inc. plans to acquire about 20% of the voting shares of Skywest Inc. under a stock option agreed upon last year, the airlines reported. Skywest is a partner in the “Delta Connection” program, in which flights are timed to facilitate passenger connections and ticketing between Delta and participating smaller airlines. Delta plans to purchase more than 1 million shares of newly issued stock in Skywest, a Utah-based regional airline, for about $6 million.
