Carnival Cruise Line said it will begin a "Be the Hero" program in which travel agents can register to receive upgrade offers that they can pass along to clients.
Agents will also earn commissions on the upgrade amounts, if clients agree to the change.
Upgrade offers will range from upgrades within the booked category, from an interior to an ocean view or balcony, and an ocean view or balcony to a suite. Upgrades are based on availability and are offered on a first-come, first-served basis, Carnival said.
Upgrade offers as part of the "Be the Hero" program will be sent to agents with eligible bookings who have registered for the program.
Once enrolled, agents may access selected upgrades for their clients via the "upgrade your client" link in the "manage booking" section of GoCCL.com.
"Our research shows that guests who sail in upgraded accommodations have a greater tendency to continue booking at that level moving forward, making this an ongoing upsell opportunity for our travel partners," said Adolfo Perez, Carnival's senior vice president of sales and trade marketing.
Offers will be sent on a weekly basis to all travel agents registered for the program starting April 11. Travel agents may register through April 4.
