Transport choices depend on the whole journey, not the fastest scheduled segment. Luggage, transfers, the final walk, and rush-hour conditions can change the practical choice.
Solve the airport journey before the first day
Use the Incheon Airport guide when you need to choose among AREX, an airport bus, and a taxi for the actual accommodation area. The final destination and luggage matter more than comparing headline travel times.
Test a repeated cross-city trip before accepting it
Use the Hongdae-to-Gangnam guide when your stay and plans create that journey more than once. It helps you judge the subway and taxi tradeoff in context and may reveal that the accommodation area needs another look.
The two current transport guides appear below. Choose the airport decision or the repeated city journey; they answer different stages of the trip.
