This should not be taken into the aircraft cabin as part of your luggage
. All hand luggage should be of the same size that will fit into the aircraft's lockers. When domestic travel forms a thorough international journey, the baggage is always checked. The appropriate international system will apply. This is so that the checker would know how much aircraft baggage allowance he/she will give to you. When the baggage is not thorough checked, then the checker will give you charge you a wrong aircraft baggage allowance. And that would be unfair in the part of the customer especially if he/she travels in distant or far flung areas. This is because he/she will be charged a very big amount of aircraft baggage allowance. These allowances includes one checked piece with total sum of dimensions but not exceeding 62 inches, 2 checked pieces with a total sum of the dimension not exceeding 62 inches when placed side by side.
