United Airlines is adding three new international routes from San Francisco International Airport with non-stop year-round service to Toronto and Melbourne, plus a new seasonal service to New Delhi.

The US carrier is also adding a second daily flight between San Francisco and Seoul, South Korea.

The expansion follows previous confirmation that the airline will open new year-round routes between San Francisco and Auckland, Tahiti and Amsterdam.

“This route expansion solidifies United's position at San Francisco as the gateway airline serving destinations across the Pacific, the continental United States, as well as to Europe and beyond,” said Oscar Munoz, United's chief executive.

“It serves as a fitting capstone to all our efforts that made 2018 a breakthrough year for United, from delivering strong financial performance to currently leading in on-time departures for the second year in a row.”

Since 2013, United Airlines has added 12 new international destinations from San Francisco. With the latest flights, the carrier will serve 29 international destinations from SFO, including eight cities in Europe, India, and the Middle East, seven in North America, and 14 in Asia and Oceania.
