Have you recently applied for an received either of these two cards? If so, they have increased the bonus miles you can earn as long as you notify them within 60 days of being approved for the card/s. Simply go into your online account with Chase and click on “Contact Us”. You can send a SM (secure Message) to them letting them know that you recently found out that they are offering more miles and you would like them to do the same for your new account. I’ve done it several times and not once did I have a problem. Again, the only caveat is that it must be within 60 days of being approved.
