Carnival Corporation & plc the world’s largest cruise travel company, has signed an agreement to offer Alipay payment services onboard its cruise ship fleet in Asia, including multiple ships in China.

The partnership will enable Chinese guests sailing with Carnival Corporation’s brands in Asia to pay for onboard products and services using the convenience of Alipay, China’s most popular mobile payment and lifestyle platform operated by Ant Financial Services Group, a related company of Alibaba, the largest online commerce company in China, the company said in a statement.

As part of this agreement, Carnival Corporation’s first and largest brand in China – Costa Cruises – will give passengers the option to use their existing Alipay accounts as a payment method for cabin folios. All onboard spending – including shopping, activities, excursions, food and drinks – will be added to each guest’s cabin folio as the purchase is made, and then cleared on a nightly basis via their Alipay account.

Alipay will debut on Costa Serena in China starting in 2017 before potentially expanding to additional ships in the Costa Asia fleet, including Costa Atlantica, Costa Victoria and Costa Fortuna in China, and Costa neoRomantica, which has been homeported in Japan since April of this year.

Based on the terms of the agreement, Carnival Corporation’s other leading brand in China and Asia, Princess Cruises, will also have the potential to offer Alipay onboard its ships sailing in Asia, including the all-new Majestic Princess that begins its first homeport season in Shanghai in July 2017 as the first cruise ship tailor-made for the Chinese market. Details of future rollout plans may be released at a later date.

Alipay is China’s most popular mobile payment and lifestyle platform with over 450 million users. It presents a significant opportunity for Carnival Corporation to ride on this digitalization trend and provide an upgraded experience for its cruise guests, offering Alipay as an additional payment option for onboard purchases.
