Flying out of San Francisco SFO
San Francisco is the most direct US gateway to South and East Asia, and the Bay Area's concentration of Indian technology professionals has made SFO–India one of the most heavily served long-haul corridors in the country. That density cuts both ways: there is real nonstop capacity, but demand around the winter holidays and the summer university calendar is severe enough that fares from Fremont, Sunnyvale and San Jose can double if you leave the booking to the last month. Early planning is worth more on this corridor than almost any other we handle.
What to know before you fly to Bengaluru
Entry requirements for US travellers
US travellers need an Indian visa; the e-Visa covers most tourist and business travel, and OCI cardholders use their OCI. Business travellers should check that the e-Visa category actually covers the purpose of the trip — verify on India's official portal.
Best time to go
Bengaluru's elevation gives it a mild climate year-round, so there is no genuinely bad time to go. October to February is the most pleasant and the busiest; fares ease through the spring and the monsoon months.
Airports and arrival
Kempegowda International (BLR) sits well north of the city — allow for the drive — and is a major hub for onward connections across South India.
Baggage
This corridor carries a lot of relocation and long-stay travel, where the difference between one and two checked bags matters more than a $50 fare gap. We price the allowance and the fare together.

San Francisco to Bengaluru — frequently asked questions
Fares on the San Francisco–Bengaluru route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include Air India, Emirates, Qatar Airways and Singapore Airlines. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer nonstop service alongside one-stop itineraries via the Gulf or Singapore, and total journey time runs about 17–19 hours nonstop, 21–25 hours with a connection. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.
Plan on 17–19 hours nonstop, 21–25 hours with a connection from San Francisco International (SFO) to Kempegowda International (BLR), including time on the ground if your itinerary connects.
Book two to four months ahead for ordinary travel, and six months or more for December, the summer school holidays and the Indian wedding season, when the cheapest fare buckets are gone long before the date approaches.
Yes — this route has nonstop service, with nonstop service alongside one-stop itineraries via the Gulf or Singapore. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 17–19 hours nonstop, 21–25 hours with a connection that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
SFO handles the Bay Area's international departures, with Oakland (OAK) and San Jose (SJC) serving domestic and short-haul routes. From the South Bay, SJC is sometimes the better start to a connecting itinerary despite SFO's bigger schedule — the drive up the peninsula at the wrong hour can cost more time than the connection saves.
This is the corridor where it matters most. US–South Asia fares carry the widest gap between the published price and the consolidator price of anything we sell, the itineraries are long enough that a better connection is worth real money, and baggage rules differ enough between carriers to change which fare is actually cheaper once you have paid for your bags. All three are things a search box cannot weigh for you. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
