An all-women cockpit crew set out on a historical journey, operating Air India's inaugural San Francisco-Bengaluru flight, going over the North Pole and taking the Atlantic route to reach the Karnataka capital at the other end of the world.

The flight number AI176 left San Francisco on Saturday at 8.30 PM (local time) and would arrive here at 3.45 AM on Monday, according to Air India sources.

Union Minister for Civil Aviation, Hardeep Singh Puri tweeted, "Way to go girls! Professional, qualified & confident, the all-women cockpit crew takes off from San Francisco to Bengaluru on @airindiain's flight to fly over the North Pole. Our Nari Shakti achieves a historic first."

Air India has said this will be the longest commercial flight in the world to be operated by it or any other airline in India.

The total flight time on this route will be more than 17 hours depending on the wind speed on that particular day, it had said in a statement on the eve of the historic flight.

Members of the crew are: Captain Zoya Aggarwal, Captain Papagari Thanmai, Captain Akansha Sonaware and Captain Shivani Manhas.
