Answer 1

Northwest allows you to carry one piece of luggage on board the aircraft plus a purse or briefcase or laptop computer or small backpack. The carry-on luggage must be of a size and shape to allow for storage in overhead compartments or underneath the seat in front of you.

Dimensions:

Cannot exceed 45 linear inches (9 inches by 14 inches by 22 inches)  

Note: Luggage not meeting these specifications must be checked and is subject to any applicable fees.
