Turkey, as a country, is no more. It’s now wants to be known as the Republic of Türkiye as its leader Erdogan is a staunch nationalist with a rather traditional view.
However Turkish Airlines, which is one of the world’s biggest airlines, is owned in part by the Turkish government, so they want to rename it as well.
Apparently the airline should become known as “Türkiye Hava Yolları”
Changing the airline’s name will be an incredibly costly exercise, as it will involved completely changing every single branded item that the airline uses, both in its planes, in airports and everywhere else. Also the new brandname is likely to lead to confusion. Whereas the English language name of the company probably helped it gain recognition in many markets the new name could prove awkward.
