谢谢楼上的回答。我也是这么想的。
只不过最近收到continental mileage plus卡寄来的一个小brochure 上书
“Your miles will not expire as long as there is activity on your credit
card account, including paying your annual membership fee, and the credit
card account is open and not in default. Upon cancellation of your credit
card account your miles will expire according to the MileagePlus Program
Rules"
我担心AA卡会不会一样效仿.
