Royal Caribbean Cruises Limited will not be resuming most cruises until at least September 15.
The company's announcement in a news release Tuesday follows similar decisions from Carnival Cruise Line and Norwegian Cruise Line.
Headquartered in Miami, Royal Caribbean Cruises originally paused travels in March and then lengthened the suspension three more times.
The decision is meant to help prevent the spread of COVID-19.
Carnival Cruise Line will not sail until at least October 1 and all Norwegian cruises, except Seattle-based Alaska voyages, will be suspended through September.
