前不久AA放出了太多太多的商务舱头等舱的saver award space，飞往世界各地，包括中国韩国，具体看这篇和这篇帖子。其中3.22之前商务舱中美单程只需55K，美欧单程50K，而AA接着很没节操的开始大卖里程，最多可获得42500miles + 10%off的折扣，相当于2 cent/mile，这个虽然不是近年来最便宜的价格(最低低至1.8 cent)，但是在这种时候(大把商务舱头等舱放出award space的时机)开卖，还是很值得入手的。
这次的促销分为两个部分，一部分是根据购买数量最多42500 miles的额外里程，一部分是购买价格打9折；第一部分的促销截止于3月1日，而第二部分9折购买必须在2月8日之前完成。所以如果没有了这个9折，售价就从2 cent变为2.22 cent/mile
购买链接戳这里，折扣和奖励具体见下面的表格：
其中最合算的购买是买100K miles，获得42500 miles的bonus，然后税后价格是$2,884，相当于2.02 cent / mile，75K miles则获得30000 bonus miles，税后价格是$2,170, 相当于2.07 cent/mile；
所以上面提到的回国商务舱55000 miles单程，现在购买只需1111刀；而美欧商务舱单程只需约1000刀。
再说一遍，2月8日之前购买才有这个价格！之后还有里程奖励但是就没有9折了。
最后附上term&condition
