Seoul to Mexico City (ICN–NLU) — Airlines, Schedules & Connections

South Korean passport holders enter Mexico visa-free for up to 180 days for tourism or business. No fee, no advance application. Passport must be valid for the duration of stay. At immigration, you receive a Forma Migratoria Multiple (FMM) entry card, which can be completed online at inm.gob.mx before arrival or filled out on paper at the airport. The immigration officer determines how many days you get, up to 180. Ask for 180 if that is what you need.

No supporting documents are formally required, but having a return ticket, hotel booking, and proof of funds speeds up the process. Losing your FMM card before departure results in a fine of about MXN 600 (roughly $35) payable at a bank before you can check in for your flight. Take a photo of it. For stays beyond 180 days, you must leave and re-enter or apply for a temporary resident visa at a Mexican Consulate.

No direct flights connect South Korea to Mexico. Route through Los Angeles (LAX), Dallas (DFW), or San Francisco (SFO) to Mexico City (MEX) or Cancun (CUN), with total travel times of 18 to 24 hours. A US transit visa or ESTA is required for connections through the US. Alternatively, connect through Tokyo Narita to MEX on Aeromexico (no US transit needed). Mexico uses the Mexican peso (MXN), trading at roughly 17 MXN per $1. No mandatory vaccinations. Uber works in most Mexican cities and is safer than street taxis.

AREX (Airport Railroad Express) runs two services from Seoul Station: the Direct Train (43 min, ₩11,000, reserved seats) and the All-Stop train (66 min, ₩4,550, unreserved). Both trains serve T1 first, then T2; confirm which terminal your airline uses before boarding.Limousine buses depart from major Seoul neighborhoods and hotels (₩16,000–18,000, 60–90 min depending on traffic). KAL and LIMOUSINE services are reliable. Taxis from central Seoul cost ₩65,000–80,000 and take 60–90 minutes. Deluxe (black) taxis are pricier but English-speaking drivers are more common.
