There is no Guwahati–San Francisco non-stop. The cleanest build is GAU–Delhi, then Air India's Delhi–San Francisco non-stop (one of the longest non-stops in the world). Air India also flies Bengaluru–SFO. Alternatives route via Dubai, Doha or Frankfurt on Emirates, Qatar or Lufthansa, or via a United hub, adding a stop but sometimes cutting the fare. A through-ticket protects bags and connections.
For tech professionals based in the South, the Bengaluru–SFO non-stop can be a useful second-leg option if your GAU feeder routes through BLR. If you self-transfer in Delhi or Bengaluru, allow at least 3–4 hours and re-check your bags for the trans-Pacific leg.
The Air India Delhi–SFO non-stop is the fastest way across, around 15–16 hours airborne, crossing the polar route. One-stop Gulf or European routings add a connection but offer more departure times and premium cabins. Compare with our Delhi to San Francisco guide before booking.
San Francisco International (SFO) is a major United hub and a key gateway for Asia traffic. If you connect onward in the US, you clear immigration and re-check bags here; allow 60–90 minutes at busy times. BART rail links the airport directly to downtown San Francisco in about 30 minutes, and to the wider Bay Area including Silicon Valley with a transfer. The AirTrain connects terminals and the BART station.
Most economy tickets to the US include 2 x 23 kg checked bags plus a cabin bag; confirm the GAU feeder matches the long-haul allowance. Economy round-trips typically range ₹90,000–₹1,55,000 depending on season and routing, with the Delhi non-stop usually at the higher end and two-stop itineraries cheaper.
Students and new hires relocating to the Bay Area often need a third checked bag; pre-paying online is usually 20–30 per cent cheaper than at the airport. If the GAU feeder is on a low-cost carrier, its allowance may be just 15 kg, far below the US long-haul allowance, so pack around the smaller limit.
Fares are usually lowest in January–February and September, outside the summer and festive peaks. Prices rise May–August and again in December. Booking 10–12 weeks ahead and keeping dates flexible delivers the best value on this very long, premium-priced route.
The San Francisco Bay Area is the heart of global tech, home to a huge Indian professional community, leading universities and major employers across Silicon Valley. The region offers familiar food, temples and Indian grocery stores, plus easy access to San Jose, Fremont and the wider valley. For Assamese students and engineers, SFO is the natural gateway to the Bay Area.
Indian passport holders need a US visa — usually a B1/B2 visitor visa or an F-1 student visa, or an employment visa such as H-1B — obtained through an in-person consular interview. Plan well ahead as appointment waits vary. See our visa guide. A B1/B2 visa is commonly issued for up to 10 years multiple-entry, with each stay's length set on arrival.
No. The fastest build is GAU–Delhi plus Air India's Delhi–San Francisco non-stop, totalling roughly 21–24 hours.
Expect about 21 to 27 hours depending on whether you take the Delhi non-stop second leg or a 2-stop routing.
Economy round-trips typically range ₹90,000–₹1,55,000, with the Delhi non-stop usually at the higher end.
