- Fares on this route are usually lowest 4 to 8 weeks before departure and rise sharply inside two weeks.

Destination guide
San Diego: 70 degrees, 70 miles of coastline
San Diego has the most reliable weather of any big US city and an airport ten minutes from downtown. Balboa Park, the zoo, La Jolla's coves and a fish-taco culture make it an easy, relaxed beach trip with strong fare competition from Southwest and Alaska.
Best time to visit: September–November is the warmest ocean and clearest skies. Spring is pleasant but 'May gray' fog is common at the coast; summer is peak for families. Winter is mild and inexpensive.
