United Airlines will begin operating three new domestic routes starting March 28, 2027, expanding its network with two coast-to-coast flights from San Francisco. The airline will offer seasonal service between San Francisco and Charleston, South Carolina, available through November 30, 2027. Year-round flights will also commence from San Francisco to Hartford, Connecticut, and Oklahoma City. Currently, none of these three cities have nonstop flights connecting to San Francisco.

In collaboration with Air Canada, United Airlines will launch three additional seasonal routes. From April 29 through October 31, 2027, seasonal daily flights will operate between Denver and Ottawa. From May 29
to October 30, 2027, Denver will also connect to Quebec City with Saturday-only flights. Seasonal Saturday-only service between Newark, New Jersey, and St. John’s will be available from June 24 to September 7, 2027. Tickets for all six new routes are currently on sale, providing passengers with expanded travel options starting in 2027.
