How is a flight number formatted and what does it represent?

• A. A three-letter IATA airport code.
• B. A booking reference for a passenger.
• C. A two-letter airline code followed by digits (e.g., JB123); identifies a specific flight.
• D. An internal crew roster number.

Answer: (C)

A flight number is formed from a two-letter airline code followed by digits, and this combination identifies a specific flight operated by that airline. The two-letter code tells you which carrier is running the service, while the digits specify the particular flight within that carrier’s schedule. This number is what pilots, dispatch, air traffic control, gates, and passengers use to refer to a single service on a given route and time. It’s not the airport code (that would identify a location), not a passenger’s reservation code, and not an internal crew roster number.
