American Express Publishing and Celebrity Cruises will produce guides for 150 destinations visited by Celebrity ships.
The collaboration includes the formation of "Celebrity's Global Insiders," a team of contributors with links to "Travel + Leisure" and other Amex magazines.
The six insiders named include Kate Betts, a former editor-in-chief at Harper's Bazaar; Marc Murphy, a chef and judge on the Food Network show "Chopped"; and Jack Ezon, president of Ovation Vacations, a company specializing in luxury travel experiences.
Content from the destination guides will appear on Celebrity's website, in brochures and onboard. Follow Tom Stieghorst on Twitter @tstravelweekly.
