It is better for you to take it as carry-on luggage in case you need it on the plane. However, please take notice that usually each business-class and economy-class passenger is entitled to have one piece of carry-on luggage; the size of each carry-on luggage should be smaller than 20 X 40 X 55 centimeter (7.8 X 15.7 X 21.6 inches) and total weight should be less than 5 kg (11 pounds).
