Cruise Lines International Association (CLIA), the world's largest cruise industry trade association, has released the 2018 Cruise Travel Report. The comprehensive analysis of cruisers and non-cruisers provides an annual overview of attitudes, behaviors and travel preferences. This year, key highlights of the study found almost all income brackets are cruising. A third (33 percent) of cruisers surveyed have a household income less than $80K, while 50 percent have a household income of at least $100K or more. The report also reveals a new generation of luxury travelers has emerged. Millennials are seeking out luxury cruises at a record pace with almost a quarter surveyed (24 percent) having sailed on a luxury cruise line within the past three years.
