The trio’s addition brings the association’s global membership to 31 cruise lines.
Clia said the lines, which were formerly regional members, “represent the global cruise industry’s ever-growing offerings”.
Cindy D’Aoust, president and chief executive of Clia, added: “Clia’s global cruise line members play a critical role in, not only our organisation, but the cruise community as a whole and every cruise line member is vital in propelling our industry forward.”
