Each airline has its own luggage policy regulating the size of carry-on and checked luggage. The regulations provide a smoother flying experience by limiting the amount of luggage in the cabin and by giving airlines a better idea of how much weight the plane is carrying.or example, Southwest Airlines (southwest.com) requires the dimensions of duffel bags to be no larger than 10 inches by 16 inches by 24 inches, and has no weight limitation for carry-ons. Measure each of your bag's dimensions -- the width, length and height -- to ensure it's within those measurements.
