Northwest Airlines has specific policies regarding baggage allowances that can vary based on several factors, including the type of ticket purchased, the destination, and the travel class. Generally, for domestic flights, passengers in economy class are allowed one carry-on bag and one personal item, such as a purse or small backpack, that fits under the seat. The maximum dimensions for the carry-on bag are typically around 22 inches in length, 14 inches in width, and 9 inches in height, including handles and wheels.
For checked baggage, the standard policy usually allows for one or two bags, with weight limits often set at 50 pounds per bag. There may be additional fees for excess baggage or for bags exceeding the weight limit. International flights may have different allowances, so it is advisable for travelers to review the current baggage policy for their specific itinerary on the official Northwest Airlines website. This will provide the most accurate and up-to-date information regarding baggage allowances, fees, and regulations.
