The airport sits about 35–45 km southeast of central Ulaanbaatar, with transfer options including airport shuttle buses (roughly 60–90 minutes, modest fares), taxis or ride-hail services (around 40–60 minutes, variable fares), and private transfers. Pros: modern terminal, international connections and comfortable facilities; cons: distance from the city and occasional delays during winter weather.

Busan is served mainly by Gimhae International Airport (PUS), a compact international and domestic gateway that often handles a mix of full-service carriers and low-cost airlines on regional routes. Located roughly 20–25 km west of downtown Busan, transfer times can be around 30–60 minutes by bus or taxi depending on traffic; the airport railroad and subway connections can take about 40–60 minutes with fares typically in the low single digits to mid-teens (USD equivalent). Ground transport is straightforward and generally affordable, though peak-hour congestion can lengthen journey times. Pros: convenient for regional travel and budget-friendly options; cons: limited long-haul connectivity and smaller terminal facilities compared with major international hubs.
