Royal Caribbean International has prolonged its fleet suspension as part of a sector-wide call to push lay-ups into mid-September.
The owner plans to relaunch its ships on 16 September, after the Cruise Lines International Association (CLIA) told members to delay US sailings to 15 September last week.
CLIA's call for postponement voluntarily extends the US Centers for Disease Control & Prevention's (CDC) April ban on passengerships within US territories to 24 July by almost two months.
"At Royal Caribbean International, our guests and crew's safety and well-being are always our top priorities," the Richard Fain-led company announced on Friday.
"After further consulting with our partners at Cruise Lines International Association and in conjunction with the CDC, we have decided to extend the suspension of sailings for our global fleet for all sailings through September 15, 2020."
The brand has also suspended its Canada sailings through October due to the country's travel ban on cruiseships.
Further, Explorer of the Seas’ revitalisation has been delayed to August given shipyard closures and supply-chain disruption amid the pandemic.
"As a result, Explorer’s August 2020 sailings will be cancelled and the revitalisation will be a technical dry dock where only routine maintenance work will take place," the brand said.
Bermuda sailings will be suspended through October, the company said.
Carnival Cruise Line has put off its sailings to October in response to CLIA's call for delay.
