Mileage accumulation is according to your applicable purchase fare class accrual ratio; you can earn both Award Miles and Status Miles after flying. On top of this, Silver Card, Gold Card or Diamond Card members will get an additional Tier Bonus. Silver Card members can earn an additional TPM×15% Award Miles while Gold Card or Diamond Card members can earn an additional TPM×25% Award Miles.
Example:
A Silver Card member who takes a one-way flight in C class from Taipei-San Francisco can earn an additional 15% Award Miles as a Tier Bonus (968 miles). Therefore, this one-way C class ticket from Taipei-San Francisco can earn a total of 12,256 Award Miles.
The calculation is 6450 (TPM of Taipei-San Francisco) × 175% (Purchased Fare Class accrual ratio) + 6450 × 15% (Tier Bonus ratio) = 12,256 miles.
