indent B2846 – not found
indent BRU846 – found
what do I need to use to find a flight ?
In FlightXML when specifying an airline with flight number, either an ICAO (BRU) or IATA (B2) code may be used to designate the airline, however ambiguous or conflicting IATA code assignments do exist so use of ICAO codes is strongly recommended.
