How do Turkish Airlines Business Class Upgrades work?

This article is about Turkish Airlines Business Class upgrades with miles or vouchers, not including paid airport upgrades, some of which are offered on demand. With miles, the logic behind Turkish Airlines is incredibly simple, because unlike Lufthansa & Co, you can upgrade every booking class to Business Class and regardless of time. In short, a Business Class Upgrade works right after you book, no matter how long you book in advance, regardless of whether the ticket is in the cheapest or the most expensive Economy Class reservation class (award tickets and reduced airline tickets). Employees are excluded) is issued and also on all routes. But that’s not all, unlike almost all other frequent flyer programs, upgrades do not work on a segment but on a track basis. <a href="https://medium.com/@Sheisamadscientist/how-do-turkish-airlines-business-class-upgrades-work-bd6880a55de9">Website</a>
