Flight Time from Los Angeles (LAX) to Busan (PUS)

The 9,616 km between LAX and PUS converts to 11.98 hours of flying under the 850 km/h + 40 min model. Model it before booking: one stop ≈ 15 h total, two stops ≈ 19 h, per the slider above.

Past the 9,000 km mark this is an ultra-long-haul sector: the 11.98 hours in the air plus cabin time makes a one-stop routing with a lounge stop worth pricing against the non-stop. Factor the 17-hour shift into recovery plans: eastbound arrivals at Busan generally bite harder than westbound ones.

If fares into PUS spike, the airports tabulated below are the first places to check; each row shows the distance back to Busan and the flight time from Los Angeles. From LAX, reaching ICN instead takes about 1 h — less airborne time than the 11.98 h non-stop, and the surface leg into Busan still has to be won back.

Where a matching calculator page exists (LAX → ICN, LAX → KIX among them) the links are in the Related list below. Ground transfer from the alternative airport back into Busan is the catch for arrivals off the LAX service: the 325 km back-offset is time you must win back in fare savings.

A 10:00 departure works out to roughly 14:59 on the clock in Busan — the 11.98 h airborne leg plus the UTC−8 → UTC+9 shift. Budget the ground side too: a standard day runs $134 in Busan versus $268 in Los Angeles (hotel, three meals, two transit rides), so the arrival city sets the trip's marginal cost.

Busan undercuts Los Angeles by $134 a day on the dataset averages; let that shape how many nights you book at each end. With 17 hours gained eastbound, the 9,616 km out to Busan ends in a serious jet-lag bill — plan a quiet first day.
