United Airlines has added flights from San Francisco International Airport (SFO) to 13 destinations, including a popular California airport recently axed from Southwest Airlines' SFO roster.

The news comes after Alaska Airlines recently announced it would slash routes from SFO. Southwest announced its own SFO cuts in July.

A United spokesperson said Tuesday the airline would increase its four daily round-trip flights between SFO and Burbank International Airport to six—Southwest recently axed the route.

Tickets for the added flights, which the airline plans to continue into 2024, went on sale Saturday, with each flight including a first-class option for premium customers.

The airline said it would also fly larger planes on the route during peak travel season to meet the "large local demand and provide more connections to popular international destinations." 

United Airlines is has a large hub at SFO and is the Bay Area's and California's largest carrier.

United has also added 12 flights from SFO due to begin in November to these destinations:

• Albuquerque, New Mexico
• Atlanta
• Bakersfield, California
• Baltimore
• Cleveland
• Monterey, California
• Nashville, Tennessee
• Pasco, Washington
• Philadelphia
• Pittsburgh
• Raleigh-Durham, North Carolina
• Spokane, Washington

In August, United announced flights to Beijing would resume on Nov. 9, with a spokesperson telling The Standard the airline had started selling tickets for 12 weekly flights between SFO and Hong Kong.

The airline also announced it would expand to daily flights from the airport to Shanghai on Oct. 1.

United also plans to launch nonstop flights daily to Manila in the Philippines on Oct. 29 and three times a week to Christchurch on New Zealand's South Island on Dec. 8. It will also offer daily flights between SFO and Australia's Brisbane and Melbourne, and twice-daily flights between SFO and Sydney, Australia.

Elsewhere in California, United also said it added flights from Los Angeles International Airport (LAX) to Cleveland and would add new nonstop flights between LAX and Hong Kong, four weekly flights to Auckland, New Zealand, and a new route to Brisbane, as well as increased service to Tokyo, Japan.
