Probably, this promoton has been noticed by all. My question is that the bonus miles will be awarded 6-8 weeks after the purchase. Which date is the actua activity date? the purchase date or the post date?

I am asking this since I need to extend expiration date of my UA account by using this promotion. My mileage will expire by the end of this month.
