Jeju scores 78/100 for Connectivity for Business Travelers. International Airport Connectivity (30%): 24/30 - Jeju International Airport (CJU) provides excellent regional connectivity with direct flights to major Asian cities including Tokyo, Osaka, Shanghai, Beijing, Hong Kong, Taipei, and Bangkok. The airport is conveniently located just 5 kilometers from Jeju City center (15 minutes by taxi/bus). However, long-haul international travelers typically must connect through Seoul's Incheon (ICN) or Gimpo (GMP) airports, limiting direct global connectivity. Domestic Airport and Rail Connectivity (25%): 21/25 - Exceptional domestic air connectivity with hundreds of daily flights to Seoul (every 15-30 minutes during peak hours), Busan, Daegu, Gwangju, and Cheongju. Flight time to Seoul is approximately one hour with streamlined check-in processes. However, Jeju has no railway system, relying entirely on air transport for mainland connections, which slightly limits transportation diversity. Public Transportation Systems (25%): 17/25 - Comprehensive color-coded bus network (blue express, green local, red rapid, yellow circular routes) connects major hotels, ICC Jeju, airport, and attractions. Buses feature multilingual announcements and digital displays with T-money card payment options. No metro or tram system exists. Urban centers like Jeju City and Seogwipo have improved pedestrian infrastructure, but the island's spread-out geography makes vehicle transportation necessary for most inter-venue travel. Alternative Transportation Options (20%): 16/20 - Diverse options including readily available taxis (standard and multilingual International taxis), Kakao T ride-sharing app with English support, bicycle and electric scooter rentals, extensive car rental services at airport and major areas, and complimentary hotel shuttle services. The variety and accessibility of options effectively compensate for the lack of rail infrastructure.
