Tips for flying San Francisco to Seoul
- Incheon has good transit facilities.
- Check Korea’s K-ETA rules.
Getting to and from the airports
San Francisco: BART trains run from SFO into San Francisco and the East Bay.
Seoul: AREX trains link Incheon with Seoul Station; Gimpo is closer to the city.
Always confirm transport times on the official airport or transit website, especially for late-night arrivals.
Getting good value without stress
Start by searching a range of dates rather than a single day; the calendar view in the results makes patterns easy to spot. Then look past the headline number. Add the bags you will really take, check whether seats are assigned free, and read what happens if you need to change your plans. Two itineraries a little apart in price can be very different in comfort: a short, well-timed connection or a nonstop flight is often worth more than a small saving.
Once a fare fits your budget and your times, it is usually wise to book rather than wait for an ideal price. Fares can rise as seats sell, and there is no reliable way to predict the bottom.
Paperwork to sort early
Make sure your passport will still be valid well after you come home, and check visa or electronic authorisation rules for your destination and for any country where you change planes. Official government websites are the only reliable source. Read your fare’s baggage allowance before you pack, and keep medicines, documents and a change of clothes in your hand luggage. Our travel checklist and baggage guide cover the rest.
