Schema: CREATE TABLE FLIGHTS (FlightNo VARCHAR, DestAirport VARCHAR); CREATE TABLE AIRPORTS (AirportCode VARCHAR, City VARCHAR)
Question: What are flight numbers of flights arriving at City "Aberdeen"?
SQL: SELECT T1.FlightNo FROM FLIGHTS AS T1 JOIN AIRPORTS AS T2 ON T1.DestAirport = T2.AirportCode WHERE T2.City = "Aberdeen"
