Speaking during Royal’s second quarterly results call on Thursday (July 28), Liberty said the change in policy would be “subject to local destination requirements” and unvaccinated passengers would still be tested.

“We also anticipate in the not-too-distant future that pre-embarkation testing for longer-duration voyages will be reduced,” he added.

Asked on the call when testing requirements for longer cruises might be lifted, Liberty predicted further easing could follow soon but did not rule out reintroducing measures if needed.

“So we’re starting off here by doing the five days or less and we’re going to look at that. But I think our expectation here, call it, in the next 45 days or so. And of course, following local requirements, which will somewhat dictate in some of our destinations, what those testing requirements will be that the majority of the testing requirements will be lifted, especially around the majority of our deployment,” he said.

“We might, depending on where the ships are going, take some additional protocols and of course, we’re going to continue to follow where Covid is in society and take the necessary actions.”

The update came as Royal announced a return to "positive operating cash flow" with the group’s entire fleet now back in service.

Average second-quarter (three months to 30 June) load factors ran to 82% and to nearly 90% in June, while the group expects third-quarter (three months to 30 September) load factors to average around 95% before "increasing to triple digits" by the end of the year.

Royal’s positivity came despite posting a US $500 million Q2 net loss, one the group said "exceeded the company’s expectations" and was "driven by better revenue and cost performance".

In its trading update, the company revealed second-quarter bookings for sailings departing in the second half of the year remained "significantly higher" than those received in Q2 2019 for the latter half of 2019.
