Bonvoy卡
4/15 Post年费
5月交了年费
6月初Post了Free Night
6/16关卡,精确地按天数prorate退回了年费
注意到MA有一条法律 “If the cardholder cancels the agreement at any other time during the year, he shall receive a refund on a pro-rata basis of two-thirds of the annual fee.”
以往的DP是不prorate直接退2/3的年费,这次则发现是prorate全部不取2/3。可能Amex现在对MA用户的算法是max(prorate, 2/3)?
