To earn the 70,000 bonus miles you must spend $3,000 in the first 3 months your account is open. You can also earn an additional 5,000 bonus miles after you add an authorized user and they make a purchase within this same time frame. Just a brief reminder, here are some of the benefits of the card:
This card does carry a $95 annual fee which is not waived the first year and this offer is set to expire at the end of the month on June 30th. Just a reminder that Chase has reportedly implemented their "5/24 rule" to this card as well as almost all of their other cards except for a select few so if you've applied for 5 or more cards in the past 2 years it might not be worth taking a hard credit hit just to get rejected.
