Crystal Cruises has revealed plans to build four new ships by 2029.

Cristina Levis, CEO of parent company A&K Travel Group, which bought the cruise line last year, announced the plans during a briefing to media and travel agents onboard Crystal Serenity at the weekend, ahead of the ship’s official relaunch today.

She said: “We have ambitious growth plans for Crystal and are proud of what we have accomplished with the relaunch of Crystal Serenity and Crystal Symphony in just under a year following the purchase of the brand.

“We are now thrilled to formally announce that we will be growing our fleet and continue to offer the most exceptional cruising experiences in the industry.”

The cruise line is understood to be preparing to sign a memorandum of agreement with two European shipbuilders.

Crystal is planning two classic cruise ships and two expedition ships.
