Cruises could begin passenger voyages from the U.S.. in mid-July, depending on cruise lines' pace and compliance with the CDC's Framework for Conditional Sailing Order, according to aUSA Today report,which cites a letter from the CDC to cruise lines.

"CDC looks forward to continued engagement with the industry and urges cruise lines to submit Phase 2A port agreements as soon as possible to maintain the timeline of passenger voyages by mid-July,"  CDC spokesperson Caitlin Shockey told USA Today.

Royal Caribbean CEO Richard Fain said on the company's earnings call that he was pleased by the CDC communication he received last night.

"Last night, the CDC issued multiple very constructive clarifications and amplifications of its conditional sail order." Fain said. "They've addressed many of the items that concerned us in the order, in a manner that takes into account the recent advances in vaccines and medical science. We believe that this communication really helps us to see a clear and achievable pathway forward to a safe and healthy cruising in the near future."

Fain added "We now have high hopes that if these details can be resolved quickly, it could be possible to restart cruising by mid-July."
