Thanks for reminding me of CP
I'm hardly the expert on all IATA / ICAO airline codes, but I'll share these (for OP and others). I can also see how some people would be confused with codes in general: Cathay is CX on sites like ExpertFlyer, but CPA on FlightAware
Some people don't know all the codes, others guess, some of us just "search"
