Cruise line abruptly adds extra charges for passengers; travelers worry others may follow

Some cruise operators are already introducing additional fees on certain trips. StarDream Cruises, headquartered in Malaysia, said it added a daily fuel surcharge to Asia sailings booked after March 20.

Some worry larger cruise lines may follow. 

"Everyone should be concerned," Tom Baker, CEO of Cruise Center, a Houston-based national seller of more than 10,000 discount cruises, told Fox News Digital.

"This war is already spreading its tentacles. It's going to impact every traveler on the planet in some capacity."

Recently, a passenger posted comments to that effect in the Facebook group Royal Caribbean Cruise Tips, Tricks and Deals.

A different commenter said, "I feel like people need to start reading the contracts and fine print."

Chris Woronka, a New York City-based director and senior equity analyst at Deutsche Bank, told Fox News Digital the fine print in cruise contracts is common.

"If you look at the fine print listed on most reservations, you will find that many cruise lines have the ability to add a fuel surcharge of approximately $9 to $12 per person, per day, when the price of a barrel of oil exceeds a generally pre-defined level," Woronka said. 

Nevertheless, two of the largest cruise companies told Fox News Digital they do not anticipate higher ticket prices or supplemental fuel surcharges in the near future.

"We do not expect any immediate impact on ticket prices or the guest experience due to current oil market disruptions," a spokesperson for Norwegian Cruise Line Holdings told Fox News Digital this week. 

A Carnival Corporation spokesperson told Fox News Digital, "We have no plans to change our current pricing model."

If surcharges are enacted, they could be temporary. A higher ticket price might stick around.

"Surcharges tend to be temporary," said Woronka. "But if there is an opportunity to perhaps embed higher fuel costs into ticket prices, that could actually have longer staying power."
