American Express Co. teased updates coming later this year to its travel-focused Platinum credit cards, announcing what it called its “largest investment ever” in a credit-card refresh.

The annual fee for the Sapphire card will jump 45% to $795. Amex did not say if there would be a fee increase.

JPMorgan Chase announced a refresh to its Sapphire Reserve premium rewards card and launched its Sapphire for Business card with premium perks for cardholders who spend an annual minimum of $75,000 and $120,000, respectively.
