Destination and traffic create the range
Myeongdong, Hongdae, Gangnam and Jamsil are different road journeys. The official Seoul airport guide publishes planning figures, but the actual metered total varies with destination, traffic, vehicle type, toll and applicable surcharge. Do not turn one central-Seoul example into a citywide promise.
Compare the group total
A taxi fare is shared while public-transport fares multiply per passenger. For several travellers, compare total spend and the transfer removed, then check that the selected vehicle can legally and physically take every passenger and bag.
Metered taxi and prebooked transfer are different offers
A metered taxi uses the current taxi framework; a prebooked transfer uses the booked zone, waiting, cancellation and luggage terms. The finder can shortlist the route type, but the final price and inclusions must be confirmed on the live provider page.
