TermFlightNumber
Business termFlight Number
DescriptionThe number of the flight.
Unique for one day within one operator, but not necessarily unique across operators. The part of the FlightId excluding the operator code (see OperatingAirlineCode). This is sometimes referred to as the "Trip Number". Reference: IATA Standard Schedules Information Manual, Feb 1997, 2.2.62. Flight Numbers are assigned by a carrier as a multi-purpose reference in connection with the planning and control of the operation of flights.
Allowed values


Comments

If FlightNumber is numeric it is recommended to pad with leading zeros until the length is three. If it is numeric and longer than three, leading zeros are removed if they exist.

Examples:

  • XX0234 -> XX234
  • XX007 -> XX007
  • XX07 – XX007
  • XX7 -> XX007

Non-numeric flight “numbers” are kept as they are. NB! Non-numeric flight numbers are a relic of systems that require FlightNumber or FlightId, and where Callsign are used as the FlightId to satisfy the system requirement. Non-numeric FlightNumbers don't really exist.
