What are the acceptable dimensions of carry-on luggage on airplanes?
Dimensions:
Cannot exceed 45 linear inches (9 inches by 14 inches by 22 inches) Note: Baggage not meeting these specifications must be checked and is subject to any applicable fees. http://www.nwa.com/travel/luggage/carryon.html
Take care !!
Air Canada lets you take two bags, each weighing up to 22 lbs. There are some size restrictions too, and each airline will have its own set of rules. Best to contact the airline specifically.
