The direct connection between San Francisco (SFO) and Delhi (DEL) serves as a vital bridge for tech professionals, families, and tourists. Operated by United Airlines, this ultra-long-haul route offers a seamless link between Northern California and the heart of India, bypassing traditional layovers in Europe or the Middle East.
United Airlines provides a consistent daily service from San Francisco International Airport to Indira Gandhi International Airport. Utilizing the robust Boeing 777-200ER, this flight covers one of the longest distances in the United network, often following a transpolar or Pacific track depending on seasonal winds.
“This route is critical for the Silicon Valley-India tech corridor. By offering a non-stop service, it eliminates the need for exhausting transfers, making it the preferred choice for business leaders, students, and the large Indian diaspora living in the San Francisco Bay Area.”
