Dividend Miles members can now take advantage of exchange opportunities at Points.com — the online exchange that allows you to combine points and miles from various loyalty programs.

There is one notable caveat, however: While any member may exchange miles or points from other programs into their Dividend Miles account, only members who hold a Bank of America Dividend Miles Visa card can exchange Dividend Miles into other loyalty currencies.

Membership in Points.com is free, but those interested in “upgrading” to a “PointsPlus” membership, can earn 700 miles when doing so.

To celebrate the partnership, Points.com is promoting a 1-million-mile giveaway — 10 prizes of 100,000 miles each. To enter, sign up for an account or make any exchange on the Points Exchange before April 30.
