Diners Club looks to have solved its merchant acceptance problem by creating an alliance with Mastercard that should be in place come year end.
When I analyzed the card last month I suggested that broad acceptance was the only true drawback.
I already carry the card because of the flexibility of its rewards program and the primary rental car insurance. When the partnership is in place I’ll be able to start recommending the card as a broad solution, and it will vie for a place in most mileage junkies’ wallets.
