Carnival Cruise Line is cancelling reservations that took advantage of “a random display of prices that were far below any reasonable promotional fare.”

In a statement to affected guests, the company said that these bookings were made over the past weekend during a planned IT maintenance project.

“We regret to inform you that we will not be able to honor your reservation request,” Carnival said, noting that refunds will be issued.

“The reservation has been cancelled, and any monies paid will be credited to your original form of payment,” the company added.

As a gesture of appreciation, Carnival is offering affected passengers a non-transferable onboard credit of $100 per stateroom.

The company said that the onboard credit will be applied to future bookings if they are made by August 31, 2026.

“Since your travel plans were just made with us, we hope you will find another itinerary that suits your vacation needs,” Carnival added.

The company’s website underwent technical maintenance during the weekend, as advised in a prepared message.

“We’re making some behind-the-scenes improvements, so a few features will be temporarily unavailable, including logging into your account and creating or managing bookings,” the message read.

Additional services, such as online check-in and making pre-cruise purchases, such as shore excursions and special dining, were also suspended.

“We expect everything to be back up and running by Saturday afternoon, May 9, 2026,” Carnival explained.

“The rest of carnival.com is working, so feel free to explore away,” the company added while inviting guests to visit their social media profiles.

Earlier this year, Carnival faced IT issues that affected some of its vessels sailing in North America, delaying departures from homeports.

At the time, the company’s President Christine Duffy issued a statement confirming the outage, adding that it did not affected navigational and safety systems.
