楼主的链接发晚了，可惜了，我这边现在已经拿不满奖励了，3月4月各消费500，加起来只有2000点。
you’re on your way to earning bonus miles. Just use your card to spend $500 or more per month in February, March and April.*
Then you’ll earn 1,000 bonus miles each month. Earn an additional 1,500 bonus miles if you reach the goal in all three months. That’s a total of 4,500 bonus miles.
Bonus miles are on top of the miles you already earn. And remember, your MileagePlus® miles never expire, so you can use them whenever you like.
