Traveling from Boise
Southwest Airlines is proud to serve Boise Airport.
Located only three miles south of beautiful downtown Boise, Boise Airport makes it easy for anybody looking to get beyond Idaho to do so. And with a variety of destinations to choose from on Southwest, travelers can pick the landing spot that’s the perfect cure for their travel bug.
Beat the desert heat of the Idaho summer with a trip to the lush cities of the Pacific Northwest. Cool off on the coast, find new heights in the big city, or enjoy a bit of both on your next voyage with Southwest. You can just as easily escape the falling winter temperatures with a journey to any of the Southwestern cities on our list of destinations. Live it up in a lively desert oasis or take it easy in a coastal climate. Meanwhile, those with a taste for adventure can see what the Rockies a little further south have to offer. Whether it is backcountry camping, a long-distance hike, or an extended weekend carving it up on the slopes and warming up in the lodge, a mountainside getaway is also yours for the taking with the help of a direct Southwest flight.
