Final answer:
The SQL statement to list flight numbers and airlines from Toronto to Hong Kong, ordered by flight number is: SELECT flight_number, airline FROM flights WHERE departure_city = 'Toronto' AND destination_city = 'Hong Kong' ORDER BY flight_number.
Step-by-step explanation:
To list all flight number and airlines from Toronto to Hong Kong, ordered by the flight number, the SQL statement would be written as follows:
SELECT flight_number, airline FROM flights WHERE departure_city = 'Toronto' AND destination_city = 'Hong Kong' ORDER BY flight_number;
This statement assumes that there is a table named flights which contains columns for flight_number, airline, departure_city, and destination_city. The WHERE clause filters flights specifically from Toronto to Hong Kong, and the ORDER BY clause ensures the results are sorted by the flight numbers in ascending order.
