Priced at $284 round trip. The route covers 5,395 miles round trip.

San Francisco is one of North America’s most distinctive city breaks, drawing travelers with its dramatic bay setting, compact neighborhoods, and easy mix of iconic sights and local character. The city rewards visitors with postcard views from the Golden Gate Bridge and Twin Peaks, waterfront strolls at Fisherman’s Wharf and the Embarcadero, and a rich urban landscape that ranges from the historic cable cars to the ornate streets of Pacific Heights and the Mission’s murals. It’s also a city best explored neighborhood by neighborhood, from the steep charm of Nob Hill to the independent shops, cafés, and Victorian homes of the Haight and Noe Valley.

The best times to visit are generally spring through fall, when the weather is often clearest and most comfortable, though San Francisco’s famously cool, changeable climate means layers are useful year-round. Beyond the landmarks, the city stands out for its food and culture: fresh seafood, sourdough bread, and a strong farm-to-table dining scene sit alongside exceptional Chinese, Vietnamese, Mexican, and Filipino cuisine. Museums, live music, theaters, and a long history of counterculture and activism give the city depth well beyond its scenery, making it a compelling destination for travelers who want both classic sights and a strong sense of place.
