Pullmantur may be returning to service despite becoming insolvent and sending its three ships to Aliaga, Turkey for scrapping.

The Madrid-based cruise outfit, co-owned by Royal Caribbean Group and Cruise Investment Holdings, filed for reorganisation under Spanish insolvency laws in late July.

The Richard Vogel-led Pullmantur ships sent to Aliaga are 2,733-berth Sovereign (built 1987), 1,828-berth Horizon (built 1990) and 2,733-berth Monarch (built 1991).

Last July, the joint venture sold 1,828-berth Zenith (built 1992) to Peace Boat, a Tokyo-based non-governmental, non-profit organisation focused on peace, human rights and sustainability.

Despite lacking a fleet at the moment, the brand has posted messages on its Facebook page indicating that it is considering a return to active sailing over the past two weeks.

"We are working on getting back," Pullmantur posted on 10 September.

"We would like to have your help giving us your opinion and we want to start dreaming... What should Pullmantur be like to make the experience perfect for you?"

Calls to Royal Caribbean were not immediately returned.

It then sent out more messages over the next few days asking for feedback on Covid-19 safety before feeling passengers out on higher ticket prices.

"Thank you for all your opinions. We've scored that you want a safe trip, with controlled capacity in both boarding and meals, with more crew that can personally serve you in each of the spaces without causing tails and agglomerations," the company wrote in a post on Monday.

"So today's question is, would you be willing to pay 10-15 % more for a safer experience or not?"

The posts attracted hundreds of comments over the past two weeks, the last one actually including some positive feedback on higher prices in exchange for stringent Covid-19 safety measures.

"Thanks for all your thoughts. We have taken note that you would be willing to accept a price increase," Pullmantur said on Wednesday in its last post.

"For this climb to be moderate, we could offer full pension and drinks in all meals to all passengers. Those who want could buy an all-inclusive bracelet. Who says yes to this option?"
