As of 2026, Norwegian Air Shuttle does not offer a traditional "Low Price Guarantee" that pays you the difference if you find a cheaper flight elsewhere. Instead, they operate on a "Dynamic Pricing" model where the price you see at the time of booking is final. However, they do offer a "Price Lock" feature (for a small fee), which allows you to hold a specific fare for up to 48 hours while you finalize your plans. If the price goes up during that time, you pay the locked-in lower rate; if you don't book, you only lose the small hold fee. For Norwegian Cruise Line (NCL), a separate entity, there is a "Best Price Guarantee" for their cruises; if you find a lower advertised price for the exact same cruise within 48 hours of booking, they will provide 110% of the difference in the form of an Onboard Credit. It is vital to distinguish between the airline and the cruise line, as their financial policies and customer guarantees are entirely independent of one another despite sharing a similar name.
