Time difference against Mexico City. In July, Seúl runs 15 h ahead of the Mexican capital (UTC+9 versus UTC−6). In January the airport operates on UTC+9, so the gap is not constant across the year: daylight saving shifts it. This is the calculation that decides whether a pre-booked ground connection still works.

What each code is for. The IATA code (ICN) is what the bag tag and the ticket use; the ICAO code (RKSI) is what flight plans, NOTAMs and flight trackers use. To follow the inbound aircraft that will become your flight, ICAO is the one that returns reliable results. And if ICN is not printed on your bag tag, the bag was not checked through to here — worth catching at the counter.

Routes to Seúl (ICN)

Our catalogue lists 1 routes into ICN, totalling 3 weekly departures and spanning 12,096 to 12,096 km. The busiest is MEX-ICN at ~3 flights a week; 1 of them carry a cached fare, spread across 1 audience profiles. Every row in this section comes from that same corridor catalogue, not from a live search.

What traffic ICN moves. By audience profile, the routes catalogued here split as: Latin American regional corridor (1). That mix explains the airport’s seasonality: family corridors spike in December and Holy Week, leisure ones follow the holiday calendar, and regional ones stay flatter across the year.

Not all of these routes fly daily. The thinnest on the list is MEX-ICN at ~3 weekly departures — under one a day. On a pair like that a cancellation is not resolved in hours: the next seat may be two or three days out, which is why it is worth avoiding the last flight before a fixed commitment.

Why some rows have no fare. Of the 1 routes listed, 1 returned a price on the collector’s last pass and the rest show a dash. A dash means the automated query got no result for that pair — not that the route is suspended or expensive. For those pairs the reference price comes from the live search, which queries current inventory.

Fare seasonality

1 routes at ICN carry a monthly minimum-fare breakdown. Between the cheapest and priciest months observed the gap reaches 63% on the widest route, which shows how much the date matters against the choice of airline at this airport.

Lowest detected fare by month on routes with data, in pesos (MXN). The cheapest versus dearest month helps you time the purchase:

The three peaks of the Mexican calendar. December, Holy Week and summer concentrate family and leisure demand at once, and in those windows price stops responding to normal lead time: cheap buckets sell out earlier and flexible fares go at a premium. Outside them, the usual pattern rewards buying 4 to 8 weeks ahead and travelling midweek. That window is a general Mexican-market rule of thumb, not a measurement of this route: our series records observed prices, not the lead time at which each ticket was bought.

Seasonality does not transfer between airports. Every pair has its own calendar: a labour corridor flattens in summer while a beach one spikes, and ICN can host both. Before assuming ‘August is expensive’, read the row for your specific route; the airport average blends demands that move in opposite directions.

Connection tips

ICN concentrates 3 catalogued weekly departures across 0 airlines, in the Asia/Seoul zone. That density is what decides how much slack to leave on a connection: the more of its own services the airline runs here, the more same-day rebooking options exist.

Aeropuerto Internacional de Incheon runs on the Asia/Seoul time zone; factor the offset from your origin city when planning connections and transfers. The busiest route at ICN is MEX-ICN (~3 flights a week). The lowest fare detected at this airport is $10,251 MXN on the MEX-ICN route. Book 4–8 weeks ahead for the busiest routes to/from Seúl; fares climb in December, Holy Week and summer. Each route guide above shows month-by-month seasonality and the lowest peso fare. That window is a general Mexican-market rule of thumb, not a measurement of this route: our series records observed prices, not the lead time at which each ticket was bought.

The cheap connection that loses the checked bag. Two separate tickets are not one itinerary: there is no interline agreement, the bag is not checked through to the final destination, and if the first flight lands late the second airline owes you nothing — it sold a different flight. The apparent saving evaporates the moment you buy a same-day replacement. On a single ticket, rebooking and the bag transfer are the carrier’s problem, not yours.
