✈️Airport Connectivity

Quality of public transport connection between the main international airport and the city centre — scored 0–100: express rail or metro under 20 minutes = 90–99; regular train or metro under 45 minutes = 70–85; dedicated bus under 60 minutes = 45–65; regular bus >60 minutes or transfer required = 20–40; taxi/rideshare only or no service = 5–15 (CAPA Airport Connectivity Index, IATA Airport Development Reference Manual, operator data 2024). This is the most nomad-specific indicator — frequent movers care deeply whether they can get to the airport at 6am without an expensive taxi. Singapore Changi: MRT Jewel line, 30 minutes from city, 24/7 service, score 98. Zurich: direct train every 10 minutes, 10 minutes journey, score 95. Japan's major airports: excellent connectivity. By contrast, many growing economies have modern airports miles from any rail network, effectively mandating taxis. Luxembourg scores highly despite small network due to free national transit including airport bus.
