Turkish Airlines is a member of Star Alliance, so Air China and Turkish Airlines can accumulate mileage with each other. But in the same airline alliance, you can accumulate mileage and exchange tickets for free. However, the rules of airlines in different alliances are not the same, so it is best to check whether it is appropriate before redemption and accumulation.

Just show the Air China voice card when checking in, but the specific accumulated mileage depends on the cabin of the ticket purchased. The cumulative rate is different. Now the mileage accumulated by the flights of Star Alliance members can be counted as graded mileage, which can be used to exchange air tickets for upgrades or something.
