Calculation of 25% tier bonus
Silver or gold card member, earning a 25% bonus of the miles they have flown during the month.
Assuming a silver or gold member flies on a paid F Class ticket and say the distance is 5.786 miles. In my reading the tier bonus is 1.446 miles (distance x 0,25) and not
4.339 miles (distance incl. class of servic bonus x 0,25). Is this correct?
