The line said the momentum in sales is the result of a "strong, established relationship" with its trade partners and continued investment in its brand profile.
MSC has seen a "significant" increase in bookings from high street agents, homeworkers, independent businesses, tour operators and consolidators, as well as large cruise specialists continuing to perform "exceptionally".
Steve Williams, director of sales for MSC Cruises, said it was "so rewarding" to see the trade supporting MSC at levels "never experienced previously" with sales at an all-time high.
