Which name is correctly matched to the code LXJ?

• A. Korean Air
• B. Jet Blue
• C. Flexjet
• D. Big D

Answer: (C)

In aviation, three-letter operator designators identify who is operating a flight in flight plans and air traffic control communications. The code LXJ is the ICAO designator assigned to Flexjet, a private-jet operator, so seeing LXJ tells ATC and routing systems that the flight is operated by Flexjet. The corresponding radio callsign typically reflects the operator’s name, so you’d hear something like Flexjet in voice communications along with the flight number. Other well-known carriers have different designators—Korean Air uses the KE/IATA and KAL/ICAO pair, JetBlue uses B6/IATA and JBU/ICAO—so LXJ wouldn’t apply to them. Big D isn’t a recognized operator with a standard three-letter designator, which is why LXJ wouldn’t match that option.
