How should I pack my suitcases?

The Jet Programme general handbook states you are allowed to bring 2 big sized suitcases, a miniture carry bag and a laptop or backpack. You should distribute your clothing evenly incase for example one piece of luggage disappears!!!!
In photo 1, we see a young american jet carrying a roller bag and a laptop bag, make sure that your laptop, game console and cameras are all in this bag as it will be in your hands the whole trip. After you reach Narita airport we will pass through customs, so those of you with can foods WILL be searched, the rest pass through to NO DECLARATIONS section, after your short bus trip to Tokyo, you will receive your one piece of bigger luggage ,your small miniture carry on and ofcourse you have your laptop bag. Your other suitcase will be sent to your address in your prefecture, now where were we... ah yes when packing make sure to carry one suit and a couple formal shirts for tokyo, and stock up on casual and semi formal clothes. Make sure your digital cameras, consoles and laptops dont get thrown like picture 2, STICK TO A LAPTOP BAG!!!
In photo 3 shows how effective and neat packing goes hand in hand, when you attempt to squash or roll clothes it creases and often looks untidy even after trying to iron, my advice flat fold all clothes and you are done. Lastly make sure as a Safffer you dont go over the 20kgs weight limit, otherwise expect a Yen charge which is unpretty! GOODLUCK!!!!!!!!!!!!!!
