Major global <a href="https://www.thenationalnews.com/uae/transport/2023/11/02/dubai-expects-double-digit-growth-in-cruise-passengers-this-season/" target="_blank">cruise companies</a> are rerouting or even cancelling voyages through the <a href="https://www.thenationalnews.com/tags/red-sea/" target="_blank">Red Sea</a> as <a href="https://www.thenationalnews.com/gulf-news/2024/02/01/houthis-attempt-three-red-sea-attacks-in-a-single-day-us-says/" target="_blank">tensions rise</a> between Yemen's Houthi militants and British and US forces. <a href="https://www.thenationalnews.com/travel/2024/01/26/icon-of-the-seas-cruise-ship/" target="_blank">Royal Caribbean</a> and MSC Cruises are among those adjusting itineraries to avoid the area, as well as Carnival Corporation, one of the world's biggest cruise operators, which has rerouted at least 12 ships across seven brands. Swiss-Italian operator MSC Cruises became the first cruise line to cancel its sailings in mid-January amid the conflict, including the 21-night voyage of MSC Opera from <a href="https://www.thenationalnews.com/tags/dubai/" target="_blank">Dubai</a> to Genoa, <a href="https://www.thenationalnews.com/tags/italy/" target="_blank">Italy</a>, and a 23-night journey of <a href="https://www.thenationalnews.com/travel/news/2021/11/28/inside-the-800-million-msc-virtuosa-dubais-largest-cruise-ship-sets-sail/" target="_blank">MSC Virtuosa</a> from Dubai to Southampton, <a href="https://www.thenationalnews.com/business/uk/2024/02/06/ai-leaders-welcome-uk-government-investment-in-agile-regulations/" target="_blank">UK</a>. “The safety of passengers and crew is the number one priority and as there was no viable alternative itinerary, the company has regrettably had to cancel the voyages,” MSC Cruises said in a statement at the time. The ships sailed empty around <a href="https://www.thenationalnews.com/arts-culture/music-stage/2024/02/05/grammy-awards-tyla-african-music-performance-award/" target="_blank">Africa</a> en route to <a href="https://www.thenationalnews.com/tags/europe/" target="_blank">Europe</a>, where they will dock until the summer season. Affected guests are able to transfer to a future journey of a similar duration free of charge, rebook on another cruise with a partial refund or pay extra to cover the difference. Alternatively, they are also being offered full refunds. Carnival-owned Costa Cruises also recently cancelled a cruise that was set to sail from the <a href="https://www.thenationalnews.com/tags/uae/" target="_blank">UAE</a> to Italy over 19 nights, departing on March 9. “As you can well understand, the critical situation that is currently affecting the maritime traffic along the Red Sea and the Gulf of Aden is constantly being monitored with the maximum attention,” Costa said in a statement that was sent to guests who had already booked their places on the ship. “Given recent developments on the security environment and future uncertainties in the area, working in close consultation with global security experts and government authorities, we have made the difficult decision to cancel the cruise that was originally planned.” Other brands under the Carnival Corporate banner, including Seabourn and Aida Cruises, have cancelled several voyages scheduled for the spring and summer seasons. This includes Aida cruises set to sail from Dubai to Hamburg, <a href="https://www.thenationalnews.com/world/europe/2024/02/05/germany-tells-minorities-we-are-on-your-side-amid-far-right-remigration-talks/" target="_blank">Germany</a>, on March 20 and <a href="https://www.thenationalnews.com/tags/abu-dhabi/" target="_blank">Abu Dhabi</a> to Hamburg on April 7. The brand's Dubai to Mallorca voyages in April have also been cancelled. The brand said in a statement that this was the “only responsible option”. It added: “It is important to us to give all guests planning security for their vacation with this early information.” The cruise line is providing passengers with alternative travel options, according to Cruise Hive, including the opportunity to rebook any voyage in Aida's programme, plus a 10 per cent voucher of their previous travel price. Seabourn, meanwhile, cancelled several trips, including Seabourn Encore's voyage departing on March 2 from <a href="https://www.thenationalnews.com/tags/hong-kong/" target="_blank">Hong Kong</a> to Dubai. It is now due to end on March 16 in <a href="https://www.thenationalnews.com/tags/singapore/" target="_blank">Singapore</a>, rather than on April 3 in the UAE. Other brands such as Princess Cruises, which also falls under Carnival Corporation, are rerouting ships away from the Red Sea and instead sailing around the Horn of Africa to avoid affected areas. Princess Cruises' World Cruise, which set sail from Los Angeles on January 18, skipped the Middle East, including the UAE and Asia. The itinerary was revised to include ports of call in Australia, then South Africa and the west coast of Africa, followed by Western Europe and the Mediterranean, before continuing its scheduled Atlantic crossing. A statement confirmed its forthcoming world cruise on Coral Princess, which is set to depart in April, is being “reworked”. Elsewhere, Silversea cancelled two voyages in January on board Silver Moon, including one from Muscat to Dubai and another from Dubai to Mumbai. It also amended the itinerary for a sailing between Aqaba and Muscat, allowing guests to disembark in Athens. At the time of writing, only spring sailings are affected, with those scheduled to set off later this year and early next year remaining unaffected. Dozens of cruises are also still scheduled to dock in Dubai and Abu Dhabi throughout February, according to cruise itinerary platform CruiseDig. While tens of thousands of passengers are being affected, the impact on cruise operators at a global level is not expected to be significant, Todd Elliott, chief executive of Floridian travel agency Cruise Vacation Outlet, told Reuters last month. “This is a small part of their overall fleet and multiyear itineraries so they will be able to overcome this easily.” Carnival Corporation said last Tuesday that its annual earnings would take a hit, but that it also experienced an “early and robust” start to the season, with booking volumes hitting an all-time high since November, according to Reuters. These changes come after a series of attacks by the Iran-backed Houthi militants, who control most of Yemen, on vessels travelling through the Red Sea and the Suez Canal in response to Israel's bombardment of Gaza. This has resulted in repeated US and UK military strikes against the Houthis. US President Joe Biden said in January that strikes against the Houthis <a href="https://www.thenationalnews.com/world/us-news/2024/01/19/us-strikes-yemen-houthis-biden/" target="_blank">are not deterring the group</a> but that such military actions in Yemen will continue, either unilaterally or <a href="https://www.thenationalnews.com/world/us-news/2024/01/13/russia-un-yemen-houthi-strikes/" target="_blank">with other countries</a>. The Biden administration has said its operations are aimed at defending the economically vital waterway that sees at least 10 per cent of global trade. By some calculations, 150 fewer vessels went through the Suez Canal in January compared to the same month last year.
