How long is the flight from Hanoi to San Francisco?

A non-stop flight from Hanoi to San Francisco takes about 14 hours and 45 minutes. The two cities are 11,758 km (7,306 miles) apart in a straight line, measured between Noi Bai (HAN) and San Francisco International (SFO).

This is a long-haul route. If there is no direct flight on your dates, a connection through a hub usually adds 2–6 hours to the journey.

The estimate assumes an average speed of about 830 km/h plus around 35 minutes for taxiing, take-off and landing. Real schedules vary with the airline, aircraft, route and winds – heading east with the jet stream, flights are often a little quicker than this. Check your booking for the exact time.

Time difference and arrival time

San Francisco is 15 hours behind Hanoi right now. A flight leaving Hanoi at 10:00 local time lands at about 09:45 local time in San Francisco. With a 15h shift, expect some jet lag: as a rough guide the body adjusts by about an hour a day, and flying west (as on this trip) is usually easier than the other way.

Why arrival times look strange

Airline schedules always show local times: departure in the departure city’s time and arrival in the arrival city’s time. Fly east and you “lose” hours – a 7-hour flight from New York to London leaving at 19:00 lands at 07:00 the next morning. Fly west and you gain them, which is how you can land in Los Angeles almost at the same clock time you left Tokyo. This calculator handles the time zones and daylight saving time for you.

How the flight time estimate works

In estimate mode the calculator measures the great-circle distance between the two cities – the shortest route over the Earth’s surface – and assumes an average speed of about 830 km/h (515 mph), plus around 35 minutes for taxiing, take-off and landing. That gives a good guide for a non-stop flight. Real schedules vary with the airline, aircraft, winds and route: flights heading east with the jet stream are often quicker than the same trip heading west, so always check your booking for the exact time.
