Cents per mile = (round trip cash midpoint × 100) ÷ round trip miles required. cpm is invariant under the trip-type toggle — only the absolute miles, cash and savings amounts change. Advantage cpm is roughly half Saver because the miles cost roughly doubles for the same seat. Miles and tax estimates as of April 2026.

Travel tips

Small things travellers like to know about Seoul.

  • Pick up a T-money card at any convenience store or at ICN — it works on the metro, city buses, and most taxis.
  • The AREX all-stop train is the cheapest airport link; the direct express is faster but costs more — compare against an airport bus if your hotel isn’t near a station.
  • Many smaller eateries and markets are cash- or local-card only; Korean terminals don’t always accept foreign cards, so carry some won.
  • Use a local map app (Naver Map or KakaoMap) — Google Maps walking and transit directions are limited in South Korea.
