With more airlines charging higher fees for checked baggage, a growing number of people 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 airports, at check-in when you depart, and at the carousel on arrival. The key to travelling with only carry on luggage, however, starts with a great bag; get it wrong and it could cost you 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 for a specific trip, and get one which combines being lightweight as well as durable. One way to get this right is to opt for a bag finished in fabric, rather than in leather or a hard shell, and another bonus here is that a material case has a little more give when it comes to packing more items. Also make sure the bag has at least one pocket on the front for your travel documents and for any liquids you’re carrying, making both easily accessible for checking in and security. Speaking of liquids, pack shampoos, mouth wash and other similar items which come 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, plan your wardrobe carefully with a focus on taking basics which you can easily mix and match, and shoes which work for any occasion. Chooser fabrics which are lightweight, won’t crush and are easy to wash and dry, and if you need to take anything heavy, wear it if possible. Vacuum bags can also be useful as you can fill them with clothes and then remove the air, but remember that using them can make your bag heavier. And when it comes to saving space, roll your clothes instead of folding them, and fill dead areas such as shoes with socks, underwear and other small items. Finally, before you pack, lay everything out on a bed to see exactly what you are planning to take, and 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.
