Is there an annual limit on miles that can be earned via the MP visa card? If there is such a limit, is it per Visa card or is it per MP acct? I ask because I will soon have the opportunity to charge a sizeable amount to my credit card and was thinking of getting a second MP visa card (and earn an additional 17,500 bonus miles for the new acct).

Subject to credit limits, of course ...

Cheers!
