Ulan-Ude’s Baikal International Airport (UUD) serves as the city’s main air gateway, functioning mainly as a regional and federal connection point with occasional international charters. Carriers are typically Russian domestic airlines and smaller regional operators, so fares can often be competitive compared with larger Far Eastern hubs. The airport lies roughly 12–16 km southeast of the city center; taxis and private transfers usually take about 20–30 minutes depending on traffic, while local buses and marshrutkas can take 30–45 minutes for a lower outlay. Pros: compact terminal, straightforward transfers and short walks. Cons: limited international connections and fewer on-site amenities than major airports.

Busan is served primarily by Gimhae International Airport (PUS), a midsize international and domestic hub that handles a mix of full-service carriers and low-cost airlines, so fares can range from budget-friendly to premium depending on route and season. The airport lies about 20–25 km west of downtown Busan (Sasang/Busanjin areas), with travel times typically 30–50 minutes by taxi, 40–60 minutes by airport bus, or about 35–45 minutes via the Busan Metro and light-rail connections; fares for public transport are usually modest. Pros: compact terminal, relatively quick transfers and several shuttle and rail options. Cons: can be busy during holidays and international connections may require careful timing for transfers.
