Norwegian Cruise Line plans to raise cruise fares up to 10% on April 1.

At the same time, the line is extending ‘wave’ selling season offers until the end of March. Chief executive Kevin Sheehan said: “We’ve seen exceptional demand spurred by our wave season promotion, particularly for the popular summer destinations.

“In fact, we surpassed our weekly booking record three times in the last eight weeks. Based on this demand, we will increase our fares on April 1. We wanted to give consumers and travel agents the opportunity to take advantage of these offers before the price increase.”
