Flights Phuket → Seoul (HKT-ICN) — THB Fares, Airlines, Frequency

Phuket to Seoul is a holiday corridor that runs mostly one way in spirit — South Korean travellers heading for Phuket’s beaches make up much of the traffic, with Thai travellers bound for Seoul filling the rest. There are around 21 flights a week and a block time of just over six hours, comfortably an overnight or daytime sector.

THB fares

Fares on HKT-ICN swing with the Korean holiday calendar. The peaks fall around the Korean winter break, Lunar New Year and the summer holidays, when seats fill early and prices climb — two to three months of lead time suits those dates. Outside the peaks, four to six weeks ahead usually secures a reasonable economy fare in THB, and Jin Air’s promotions are the cheapest option for light packers.
