Service to both destinations will be farmed out to commuter airlines.
The daily service to Boise, operated by SkyWest Airlines, will begin Nov. 1 with a flight scheduled to depart Boise Airport at 10:20 a.m. Mountain Time and arrive at Lindbergh Field at 11:25 a.m. Pacific Time. It will leave San Diego at 5:35 p.m. Pacific and arrive in Idaho at 8:40 p.m. Mountain.
The schedule will allow travelers to connect in San Diego with flights to and from Los Cabos, Baja California, according to Alaska Airlines.
The seasonal service to Mammoth Lakes will start Dec. 19, operated by Alaska’s primary commuter affiliate, Horizon Air.
“San Diego has always been an important market for Mammoth,” said Howard Pickett, Mammoth Mountain Ski Area’s chief marketing officer. “Our partnership with Alaska Airlines and the new route gives San Diego residents the ability to get to the ski slopes in a fraction of the time.”
The flight will be scheduled to depart Lindbergh Field at 5:30 p.m. Sunday through Friday, and arrive at Mammoth Yosemite Airport at 7 p.m. The return run will leave the ski resort at 7:30 p.m. and arrives in San Diego at 9 p.m.
On Saturdays, the flight will leave San Diego at 9:30 a.m. and arrive in Mammoth Lakes at 11 a.m. The Saturday return flight will depart at 11:30 a.m. and land at Lindbergh Field at 1 p.m.
The new flights will give Alaska Airlines 25 daily departures from San Diego with nonstop service to 12 domestic and two international destinations.
