Looking for cheap flights from Bangalore to San Francisco? FlightGPT compares live BLR to SFO fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Bangalore to San Francisco non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Bangalore-San Francisco fare is one search away.
There is currently no non-stop Bangalore–San Francisco flight. Air India's BLR → SFO non-stop (AI 176) ended on 27 February 2026 after months of operating with a technical fuel stop via Kolkata, a knock-on effect of the Pakistan airspace closure. Today the realistic choices are one-stop: Air India via Delhi (connecting to the surviving DEL → SFO flight), Emirates via Dubai, Qatar Airways via Doha, Singapore Airlines via Singapore, Cathay Pacific via Hong Kong, and United via a European or Asian gateway. Total journey times run roughly 20–26 hours depending on the layover.
The great-circle distance is about 13,750 km — one of the longest city pairs from India. With one stop, expect 20–24 hours total for an efficient Gulf or Asian connection (Doha, Dubai, Singapore, Hong Kong) and longer if the layover is loose. Asian-hub routings (Singapore Airlines via SIN, Cathay via HKG) are often the most comfortable for managing jet lag, since they break the journey roughly in half and arrive into SFO's International Terminal.
Fares peak in May–August (summer / school holidays), around Thanksgiving and Christmas (late November–January), and during Diwali. The cheapest windows are usually late January–February and October–early November. For summer or year-end travel, book 14–20 weeks ahead; 8–12 weeks is enough for shoulder season. Live fares move daily — check current prices in the FlightGPT search.
One-stop Asian and Gulf carriers (Singapore Airlines, Cathay Pacific, Qatar, Emirates) are usually cheaper than building a separate ticket through Delhi. Search 3–5 dates around your plan — long-haul fares swing widely day to day. Tuesday and Wednesday departures generally beat weekends. If you only need to reach the Bay Area, also price one-stops into San Jose (SJC) or Oakland (OAK), which can undercut SFO. Compare every connected source live in the FlightGPT search rather than assuming the non-stop premium still exists — it no longer does on this route.
Bangalore (BLR) — Kempegowda International Terminal 2 (T2), the 'Garden Terminal', handles all international departures. Allow 90–120 minutes for check-in, immigration and security. San Francisco (SFO) has four terminals; almost all India-connecting one-stops arrive at the International Terminal (Boarding Areas A and G). US CBP processing for Indian B1/B2 holders uses the officer queue (allow 45–90 minutes). BART rapid transit reaches downtown SF in about 30 minutes (~USD 11); Caltrain and rideshare serve Silicon Valley.
On India–US itineraries, full-service economy typically allows 2 × 23 kg checked + one cabin bag; business gets 2 × 32 kg. Allowances follow the operating carrier and fare bucket, so a Gulf or Asian one-stop may differ from Air India. For Air India specifics see Air India baggage. Pre-paying excess online is almost always cheaper than at the airport — useful on this relocation-heavy route.
Indians need a US B1/B2 visitor visa (fee USD 185), applied at the US Embassy in New Delhi or a Consulate in Mumbai, Chennai, Kolkata or Hyderabad. Appointment wait times vary widely by post — check the official US State Department wait-time page before booking flights. The visa is typically valid 10 years, multiple entry. Many BLR–SFO travellers fly on H-1B or L-1 work visas, which follow a separate employer-sponsored process. See the Visas guide.
Doha (Qatar) and Dubai (Emirates) give the widest schedule and frequent same-day connections. Singapore (Singapore Airlines) and Hong Kong (Cathay) split the trip more evenly eastbound, which many travellers find easier on the body. Delhi (Air India) keeps you on one carrier and one ticket, but the onward DEL → SFO leg currently includes a Kolkata refuelling halt. Pick the hub by layover length and total time, not just headline price.
Choose a one-stop that lands SFO in the afternoon/evening so you can sleep on local time and beat jet lag. Pre-book an aisle seat, hydrate, and walk during the layover. Order a special meal (VGML, HNML or AVML) at booking. Because crossing the International Date Line and a 12.5–13.5-hour time difference is brutal, give yourself a buffer day before any meeting. Confirm your US visa is valid well before you travel.
San Francisco is the gateway to Silicon Valley and one of the most scenic US cities — the Golden Gate Bridge, Alcatraz, cable cars, Fisherman's Wharf and the wine country of Napa and Sonoma a short drive north. For Indian visitors it's a hub for tech work, university trips and family visits, with a large diaspora and easy access to the wider West Coast (Los Angeles, Seattle, Las Vegas, the national parks).
