Cheap Flights to Bangalore

From the USA to Bangalore and back, the cost is from about $780–$900 in the cheapest months (notably February, September, and October) up to roughly $1,300–$1,450 during the May–June and December peaks, depending on the departure city, airline, and how far ahead you book.

No, sorry - Air India’s nonstop San Francisco–Bengaluru flight was suspended as of February 27, 2026, due to persistent Pakistani airspace restrictions that necessitated at least one refuelling stop. SFO–Bangalore itineraries now require a connection (typically in Delhi).

February is generally the cheapest month to fly to Bangalore from the U.S, with a fare of approximately $850 for both ways. September and October are almost the same, following the end of monsoons, both costing a price of about $780-800.

The ticket price costs around $780 in the lowest-fare months to as much as $1,450 for a round-trip economy ticket from the USA to Bangalore during the December holiday peak. So plan accordingly.

Not anymore - Air India suspended its nonstop service between San Francisco and Bengaluru as of February 27, 2026. Currently, all flights from the USA to Bangalore require at least one stop.

No, it's cancelled. Air India cancelled its direct SFO-BLR service effective February 27, 2006. It was due to Pakistani airspace limitations, which made it far too expensive for Air India's nonstop Boeing 777 service from San Francisco to Bengaluru, leading them to cut their services. Air India said that once Pakistani airspace is reopened, it intends to restart its non-stop service.

Since Air India discontinued their nonstop flights, you'll find that the cheapest alternative to book from San Francisco to Bangalore would be with a connection in Delhi (with Air India) or Doha, Dubai, or Abu Dhabi with Qatar Airways, Emirates, or Etihad Airways. You may want to consider booking a bit in advance-about 5–8 weeks before take-off- and flying in February, September or October for the better rates.

They did, for now - Air India ceased its nonstop service between Bengaluru and San Francisco and between Mumbai and San Francisco on February 27–28, 2026. The airline’s Delhi–San Francisco route is an exception - it actually increased its frequency from 7 to 10 weekly flights as of March 2026.

Not at the moment - as mentioned above, Air India’s SFO-BLR service was suspended as of February 27, 2026. The airline has committed to resuming nonstop service as soon as the situation permits.

A one-way flight from SF to BLR (via Delhi) would be 25 hours of flying. The return trip from Bangalore to SF has a layover in Kolkata and would probably take close to 28 hours of flying. Before Air India eventually discontinued its SFO-to-BLR non-stop service, it used to take 17 hours used to be the longest-ever flight by an airline.
