We have all been there, sitting on our suitcase trying to close it with enough crammed in to last us a good few months not weeks! By over cramming our cases we not only risk with it weighing too much but could also cause it to split open as it is being transport from the airport to the plane and back again.
Vacuum bags are a great way to save space. Obviously many of us will not have access to a vacuum at our destination but you don’t really need one. Squashing the air out of the bag manually and sealing it will still save a lot of space. When doing this it is important to remember that although the clothes will take up less room they will still weigh the same, so be sure to have a set of scales handy to check you are still within your luggage allowance.
