National and local systems use different tickets and reservation rules.
Think in four layers
Airport access, intercity rail or bus, city subway and the final local bus are separate layers. Each can use different tickets, stations and operating rules.
Reserve only what needs reserving
KTX and intercity buses may need a specific departure, while ordinary subway and local-bus journeys are usually flexible. Keep reservation details separate from the reloadable transit card.
Transfers need real walking time
Major stations and terminals are larger than they appear on a map. Include corridors, exits, elevators and the walk to accommodation, especially with luggage.
Prepare for the last connection
Check the final useful subway, bus or ferry for the specific direction and date. A late intercity arrival is not helpful if the onward local connection has ended.
Before you act
- Identify the ticket needed for each layer.
- Save station and terminal names in Korean.
- Allow walking time inside interchanges.
- Check the last local connection.

Does one transit card cover every journey?
No. Many local journeys accept one, but reserved intercity travel normally needs separate tickets.
Should I compare rail and bus?
Yes. The better option depends on the actual origin, destination station and final transfer.
