If you thought what, and how, you pack your suitcase has no part in saving money when you travel, you’d be wrong. With more airlines charging higher and higher fees for checked baggage, a growing number of people are seeking to go on holiday with only a carry on bag. Not only does this save on checked baggage fees but it also can save time at the airport, both on check-in and at the carousel. The key to travelling with only carry on luggage, however, starts with a great bag; get it wrong and it could cost money. When choosing a bag, make sure it is the right size for the airline you travel with the most, or are planning to travel with, and make sure it is as lightweight as possible when empty. One way to help get this right is to opt for a bag finished in fabric, rather than leather or a hard shell bag. With material cases there is also a little more give when it comes to packing a lot of items into it. Also make sure it has at least one pocket on the front for your travel docs, and for any liquids you’re carrying, making both accessible for checking or security. Speaking of liquids, pack shampoos, mouth wash and other similar items in 100ml sizes; most pharmacies and some supermarkets stock small travel sizes, or you can buy travel sized bottles and fill them up with your own products from home. When it comes to clothes and shoes, take care to plan your wardrobe, with a focus on taking basics which you can easily mix and match from, and shoes which work for any occasion. Aim for fabrics which are lightweight, and easy to wash and dry, and if you need to take anything heavy, wear it. Vacuum bags can also be useful as you can fill them with clothes and then remove the air, but using them can make your bag overweight, also roll your clothes instead of folding them, and fill spaces such as shoes with socks, underwear and other small items. Finally, before you pack, lay everything out to see exactly what you are planning to take on holiday, then cull anything you might not use. You might regret packing that extra pair of sandals which meant your ebook reader had to stay behind at home.
