United Airlines’ 4 New and Returning Routes:
| Route | Launch date and operating period | Frequency | Planned aircraft |

Chicago Gains New Nonstop Route to Bermuda
United’s Chicago O’Hare to Bermuda service will begin on April 3, 2027, with flights scheduled every Saturday during the summer season. The route will provide a direct connection between the Chicago area and the British Overseas Territory in the North Atlantic.
Bermuda lies approximately 650 miles off the coast of North Carolina and attracts visitors with its beaches, coastal scenery, and tourism offerings.
According to The Points Guy, The new service will give travelers from Chicago and the wider Midwest a nonstop option instead of requiring a connection through another airport.
United already operates nonstop flights to Bermuda from Newark Liberty International Airport (EWR). The Chicago addition will establish a second United departure point with direct service to the island and extend access to Bermuda through the airline’s Chicago hub.
O’Hare’s connecting network also provides travelers from other parts of the United States with additional ways to reach Bermuda, depending on available connections and travel dates.
The new route is subject to government approval, according to the Bermuda Tourism Authority.
San Francisco Hub Adds 3 Domestic Connections
San Francisco International Airport will account for the other three routes in the expansion.
United plans to launch service to Charleston and restore its connections to Hartford and Oklahoma City, giving travelers additional nonstop options between the West Coast and these US markets.
San Francisco to Charleston, South Carolina
United will launch service between San Francisco and Charleston International Airport (CHS) on March 28, 2027. The route is scheduled to operate through November 29, with four weekly round-trips during the summer season.
The new connection will give travelers from the San Francisco Bay Area a direct option to reach Charleston, a coastal city known for its historic districts and tourism attractions. Passengers will have an alternative to itineraries that require a connection through another airport.
United plans to operate the route with a Boeing 737 MAX 8. The published schedule sets out a seasonal operating period rather than year-round service.
San Francisco to Hartford, Connecticut
United will resume daily flights between San Francisco and Bradley International Airport (BDL), which serves Hartford and surrounding communities, beginning March 28, 2027.
The airline last operated the route in September 2018. Its return will restore a nonstop link between Northern California and central Connecticut, providing options for business travelers, visitors, and passengers traveling to the wider New England region.
The service is scheduled to use a Boeing 737 MAX 9. Daily operations will offer departures throughout the week, subject to the final published schedule.
San Francisco to Oklahoma City, Oklahoma
United also plans to restore daily service between San Francisco and Will Rogers World Airport (OKC), beginning March 28, 2027.
The airline ended its previous San Francisco to Oklahoma City service in April 2020, during the early months of the COVID-19 pandemic. The planned return will re-establish a nonstop connection between the San Francisco Bay Area and Oklahoma City.
Unlike the other three routes in the expansion, this service will use an Embraer 175 regional jet. The aircraft will operate under United Express, with SkyWest Airlines identified as the regional operator in schedule reporting.
The return of this route will give passengers a new opportunity to travel between the two cities without changing planes, depending on their departure and arrival requirements.
Aircraft and Frequency Details
United’s planned aircraft assignments vary by route. The Chicago to Bermuda service will use a Boeing 737, while the San Francisco to Charleston and Hartford flights are scheduled with Boeing 737 MAX aircraft. The Oklahoma City connection will operate with an Embraer 175 regional jet.
The airline has also set different operating frequencies across the four routes. Bermuda will receive one weekly flight, Hartford and Oklahoma City will receive daily service, and Charleston will receive four weekly round-trips during the summer season.
These differences reflect the schedules filed for the individual routes. Travelers should confirm departure dates, aircraft details, and operating frequency when booking because airlines can revise schedules before launch.
How 4 Routes Fit United’s 2027 Plans
The latest expansion follows a larger international announcement that United made in August 2026.
That plan included ten new international cities and three additional international routes across Europe and Asia, with services scheduled to begin during 2027. Details are available in the airline’s official announcement.
United also announced additional Canada-US services with Air Canada on October 16, 2026, as part of their transborder joint business agreement.
The changes include United’s seasonal service from Newark to St. John’s, Newfoundland, along with new service from Denver to Ottawa and Québec City. St. John’s is expected to become United’s easternmost destination in Canada.
The wider transborder changes strengthen connections between Canadian cities and United’s US hubs.
The 4 route expansion complements those plans by adding a Bermuda connection from Chicago and increasing service options from San Francisco. The Canada developments are detailed in Air Canada’s announcement.
What Travelers Should Know
The route expansion gives travelers more options for planning trips during spring and summer 2027.
The Chicago to Bermuda flight will add a seasonal international connection, while the three San Francisco services will expand access to destinations in South Carolina, Connecticut, and Oklahoma.
Travelers considering these routes should review United’s booking system for confirmed departure dates, flight times, seasonal operating periods, and aircraft assignments.
Final schedules remain subject to change, and the Bermuda service is subject to government approval.
Bottom Line
United Airlines’ 4 route expansion will introduce a new Chicago to Bermuda service and restore or add 3 routes from San Francisco in 2027.
The changes will strengthen connectivity across six cities while building on the airline’s broader international and transborder network plans.
With the Bermuda service beginning on April 3 and the San Francisco routes scheduled to start on March 28, the expansion will offer new travel choices for the spring and summer seasons.
