The Norwegian Air Baggage Allowance Policy is clear but varies depending on the ticket type. For low-cost tickets, passengers are allowed one personal item, with additional baggage requiring extra fees. Cabin luggage allowances are typically 10kg for low-cost options and 15kg for premium fares. Checked baggage is offered in several weight categories, ranging from 20kg to 32kg, with additional charges for excess weight. Overall, while the policy is straightforward, travelers should be aware of the additional fees for extra baggage.
