Carnival Cancels Some Cruise Bookings After Website Glitch Shows Unusually Low Fares

Carnival Cruise Line has started canceling some bookings made during a recent website outage, after a pricing glitch appeared to show cruise fares at far lower rates than usual.

The issue happened during a planned IT maintenance period over the weekend of May 8, 2026. Carnival expected the work to take 18 hours, but the disruption stretched longer than planned. During and after that window, some guests reported seeing unusually cheap fares on Carnival’s website, including balcony cabins that appeared to cost a fraction of the usual price.

For cruisers who managed to book one of those fares, the excitement didn’t last long.

Carnival has since told affected guests that the reservations will not be honored. The cruise line is refunding payments and offering a $100 onboard credit per stateroom for guests who make a future booking by August 31, 2026.

Carnival Says the Fares Were Displayed by Mistake

In messages sent to affected guests, Carnival said the fares appeared after its planned IT maintenance project and were not valid promotions.

The cruise line described the prices as “far below any reasonable promotion fare” and told affected guests it would “not be able to honor your reservation request.”

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

That explanation may make sense from the cruise line’s side, but it hasn’t stopped some guests from feeling let down. Once a booking is confirmed and paid for, even a too-good-to-be-true fare can start feeling like a real vacation.

Guests Reported Balcony Cabins at Surprisingly Low Prices

The pricing issue quickly became a talking point online, especially after cruisers started comparing what they had seen on Carnival’s website.

One Reddit user said they managed to book a solo balcony cabin on a six-day cruise for around $300 total after the site maintenance. “Hoping Carnival will honor the price because it was quite literally a steal,” they wrote.

Other users claimed they saw balcony cabins for even lower per-person fares, with one saying they had spotted rates around $130 per person. Another said they had seen seven-day balcony cabins showing at $365 before the fares disappeared.

A newer Reddit discussion showed the mood after cancellations started landing in inboxes. One poster said they had booked and paid for a balcony cabin, then received the cancellation email from Carnival.

“I paid $400 for a 6-day cruise for one person,” the Reddit user wrote, adding that the room was priced more like an interior cabin than a balcony.

Not everyone in the discussion agreed Carnival should have honored the bookings. One commenter wrote, “It’s in their terms and conditions….good luck fighting this.” Another said the situation was disappointing but pointed out, “this could cost them millions,” while noting that Carnival was at least offering onboard credit.

Others were more critical. One commenter said, “I’m not trying to get into a legal battle. I just think it’s a sh***y thing to do.”

That split reaction is pretty much what you’d expect. Some guests see it as a company mistake that Carnival should stand behind. Others see it as a clear error that was never likely to stick.

The Planned Maintenance Turned Into a Longer Timeline

The pricing problem came during a wider disruption to Carnival’s booking systems, and the dates matter here because the outage didn’t follow the original schedule.

Carnival’s planned maintenance began at 9 p.m. ET on Friday, May 8, 2026. The cruise line initially expected systems to be restored by 3 p.m. ET on Saturday, May 9, which would have made it an 18-hour maintenance window.

By the afternoon of Saturday, May 9, the work was still not finished. Carnival then pushed the expected return time to 5 p.m. ET, while warning guests and travel advisors that the downtime could extend beyond that. It did.

On Sunday, May 10, Carnival sent another update saying maintenance was still in progress. That message also reportedly told guests, “Please be assured that no bookings will be cancelled as a result of this downtime.”

During the outage, guests and travel advisors had trouble with several online services. That included making new bookings, managing existing reservations, making payments, checking in online, buying Fun Shop items, and accessing booking dashboards.

Carnival’s contact centers were also affected, which meant representatives were limited in how much help they could offer for reservation-related issues during the downtime.

The low-fare reports started appearing after the maintenance window failed to return to normal as planned. By Tuesday, May 12, 2026, affected guests began receiving cancellation notices from Carnival, with the cruise line treating those bookings as pricing errors rather than normal reservations made during downtime.

That timeline is why some guests are especially annoyed. Carnival had said bookings would not be cancelled because of the downtime, but the cruise line is now drawing a line between downtime issues and fares it says were displayed by mistake.

Carnival Festivale Bookings Were Among Those Affected

Some of the deeply discounted fares appeared to involve Carnival Festivale, Carnival’s upcoming Excel-class ship.

Carnival Festivale is scheduled to join the fleet in 2027 and will be the next ship in the same class as Mardi Gras, Carnival Celebration, and Carnival Jubilee. The ship is expected to sail from Port Canaveral after crossing the Atlantic from Europe.

Because it’s a new ship, some cruisers argued the low fares were obviously too good to be true. One social media commenter said, “When it sounds too good to be true it usually is.”

Still, that doesn’t mean affected guests aren’t annoyed. Once a booking confirmation lands and money leaves the account, it can feel real fast — especially if someone starts planning flights, time off work, or family schedules around it.

Carnival Festivale has been drawing attention because of its family-focused features, including Sunsation Point, Carnival WaterWorks Ultra, and around 1,000 interconnecting cabins. That may explain why some guests moved quickly when they thought they had spotted a bargain.

What Affected Guests Are Getting

For guests whose bookings were cancelled because of the pricing glitch, Carnival says payments will be refunded.

The cruise line is also offering affected guests $100 in onboard credit per stateroom, provided they make another Carnival booking by August 31, 2026.

That onboard credit can help, but for guests who believed they had secured a balcony cabin for a tiny price, it may not feel like much. A $100 credit doesn’t recreate the fare they thought they had booked, and it also doesn’t cover the disappointment of losing a trip they may have already started planning.

At the same time, mistake fares are not unusual in travel. Airlines, hotels, and cruise lines have all dealt with incorrect online prices before. Sometimes companies honor them for goodwill. Sometimes they don’t.

In this case, Carnival has chosen not to honor at least some of the bookings made during the glitch.

What Cruisers Can Take from This

For cruisers, the practical takeaway is fairly simple: if a fare looks wildly lower than normal, especially during or shortly after a website outage, it’s worth waiting for confirmation before making other travel plans.

That doesn’t make the cancellations any less frustrating for affected guests. Once a booking confirmation arrives and payment goes through, many people naturally start thinking of the trip as real.

Carnival’s position is that the fares were displayed in error and were too low to be treated as valid promotions. Some guests agree with that. Others feel the cruise line should have done more after the bookings were accepted.

Either way, the situation is a reminder that website glitches can have real consequences when they involve vacations, money, and limited-time travel plans.
