Reading this page
The departures column counts the number of distinct routes filed in the OpenFlights schedule from each airport. A hub with hundreds of departures is a major connecting point; a regional field with a single-digit count typically supports a small number of feeder flights to the nearest hub. The list does not weight routes by frequency or seat capacity, so two airports with similar departure counts can carry very different passenger volumes in practice.
For the most current operational picture, cross-reference an airport page with the airline's own website. The underlying dataset is community-maintained and reflects scheduled-route relationships rather than a live timetable.
Country pages on AeroRoute Guide are short on purpose. They answer one travel-planning question: which airports and carriers are worth knowing in South Korea. If you're routing a trip, start at the top of the airports table and work down. If you're researching a specific airline, jump from the airlines table to the carrier profile for its full destination map. Cross-links between countries, hubs, and routes mean a single click usually moves you from a high-level overview into operational detail. When the data shows zero registered carriers, the country isn't unreachable. It almost always means scheduled service comes from foreign airlines based elsewhere, and those flights show up on the relevant airport pages.
