Seattle-based Alaska Airlines will begin rolling out daily flights to six new destinations from San Diego International Airport near summer’s end.

By year’s end, the airline is scheduled to bring the total number of cities to which the airlines flies directly from San Diego to 28.

On Aug. 27 and Aug. 28, the airline will begin nonstop service to Austin, Texas, and to Omaha, Neb., respectively.

Alaska will add daily flights to Albuquerque, N.M., on Oct. 18, and to Minneapolis/St. Paul, Minn., on Nov. 18. Its planes will begin taking off daily for Kansas City and St. Louis, Missouri, on Dec. 15.

Previously announced new routes include daily nonstop flights between San Diego and Baltimore, which started Wednesday; three-times-daily service between San Diego and Sacramento, scheduled to start Thursday; and daily service between San Diego and Mexico City. The schedule for flights to Mexico City is pending government approval, Alaska said.

"Alaska Airlines has grown more than any other carrier in San Diego over the last five years, with the addition of 18 nonstop destinations and nearly twice as many departing seats," said John Kirby, vice president of capacity planning at Alaska Airlines.

Based on passenger traffic, Alaska Airlines is the seventh-largest U.S. airline, according to the company.
