Hi Nigel,

Thanks for your review. 

As a flight search engine, Skyscanner uses the International Air Transport Association (IATA) designations as they're the standard for international air travel. This is what the airline industry uses, and so we also use those designations. As and when IATA change their designation, we will of course also make that change on our systems to reflect this.

Thanks again for your message, and for using Skyscanner.

Best regards,

Martina
