How long is the flight from San Francisco to Seoul Korea?
San Francisco, CA (SFO) to Seoul (SEL)
Shortest Flight Duration 12 hours 10 mins
The distance between San Francisco and Seoul, Korea is 5613
miles (9033 km).
To make a minor correction Seoul does not use airport code SEL
for Seoul, namely because the original airport just outside of
Seoul was Kimpo (airport designation GMP) and once air traffic
increased after the Seoul Olympics, a bigger international airport
was built in Incheon, South Korea which sits about 45 miles
south-west of Seoul (airport designation ICN) and has been used for
international use since 2001.
As for the length of flight it varies: with good tail winds I
have encountered flights just under 9 hours via Asiana Airlines but
when I travelled with United to cut costs it took over 11 hours
(major turbulence on the United Flight whereas the Asiana flight
was quite steady). So the 12 hours is slightly above average since
in all my travels to Korea it's been around 10 hours.
