Flown by United
United Airlines has introduced a new nonstop connection between Northern California and the heart of Catalonia. This route links San Francisco International Airport directly with Barcelona-El Prat, providing a streamlined travel option for those heading to Spain's Mediterranean coast.
The SFO to BCN service is a seasonal summer route scheduled to launch in 2025. United operates this flight daily using the high-capacity Boeing 787-10 Dreamliner, catering to the high demand for trans-Atlantic summer travel.
“This direct flight significantly reduces travel time for West Coast passengers who previously had to connect via East Coast hubs like Newark or European gateways like Frankfurt. It strengthens the link between the tech hubs of Silicon Valley and Barcelona.”
