Ulan-Ude’s Baikal International Airport (UUD) acts as the region’s primary gateway, handling most domestic flights and a limited number of international services. Carriers are typically Russian regional and national airlines, with budget operators offering occasional cheaper connections; fares can be moderate compared with larger hubs. The airport sits about 12–16 km southeast of the city center, reachable by taxi in roughly 20–30 minutes or by local bus and marshrutka in about 30–45 minutes; fares for shared transport are usually low while private transfers cost more. Pros: convenient for regional transfers and less crowded than major airports. Cons: fewer flight choices and limited on-site amenities compared with big international hubs.

Barcelona is served mainly by Barcelona–El Prat (BCN), Catalonia’s international hub and the city’s primary airport for long-haul and European flights. BCN typically handles full-service carriers as well as low-cost airlines, so fares can range from premium to budget depending on carrier and season. The airport lies about 12 km southwest of the city centre; onward travel options include the Aerobús shuttle (roughly 25–35 minutes, moderate fares), Rodalies/RENFE train (25–30 minutes, low fares), metro L9 (35–45 minutes, inexpensive) and taxis (20–30 minutes, higher fares). Pros: good international connectivity and multiple transport choices; cons: can be busy at peak times and terminals are spread out, which may add transfer time. Barcelona also sees occasional general aviation and private flights at smaller fields, but El Prat is the main gateway for most travelers. For those prioritizing budget carriers, nearby Girona–Costa Brava (GRO) and Reus (REU) airports can be alternatives for certain low-cost routes, typically located 70–100+ km from Barcelona and requiring longer bus or transfer connections that can take 75–120 minutes and vary in price. Pros of these alternatives: often lower ticket prices; cons: longer ground journeys and less frequent public transport connections compared with El Prat.
