SELECT T1.AirportCode FROM AIRPORTS AS T1 JOIN FLIGHTS AS T2 ON T1.AirportCode = T2.DestAirport OR T1.AirportCode = T2.SourceAirport GROUP BY T1.AirportCode ORDER BY COUNT(*) DESC LIMIT 1
Apa kode bandara yang memiliki jumlah penerbangan tertinggi?
CREATE TABLE FLIGHTS (DestAirport VARCHAR, SourceAirport VARCHAR); CREATE TABLE AIRPORTS (AirportCode VARCHAR)
