When packing for a trip, maximizing luggage space is essential to streamlining your travel process. Airlines charge high rates for additional checked luggage plus hauling a heavy suitcase through airports and along your travels can be quite frustrating. For an extra checked bag from the U.S. to Australia, Delta currently charges $60 for a second bag and $200 for a third bag while Qantas charges $90 for a third bag after the first two being free.

So when traveling abroad, try to follow these simple rules for making the most of your luggage space:

1. Only pack items of clothing that can be worn at least three items on your trip. If it can only be worn once, don’t bother taking up the space in your bag. For example, instead of taking a pair of high heels that you’ll only wear to the theater one night, pack some stylish, yet versatile dress boots that can be worn to the theater but also more casual dinners.

2. Ensure the clothing you pack can be mixed and matched, meaning everything should coordinate in some way for easy swapping of tops and bottoms to create different outfits. This packing method minimizes the number of clothing items needed while still ensuring you don’t look like you’re wearing the same outfit daily.

3. Never pack basic items you can easily buy in your destination, such as toiletries, batteries and snack food. These items utilize precious luggage space when you can just purchase them in your destination. You may not be able to find your favorite brand and prices may be slightly higher, but at least you won’t have to lug around extra weight.

4. Pack your suitcase a few days in advance and then review its contents just before departing to remove anything you’ve realized isn’t necessary. Given a few days to contemplate your packing, you likely will recognize some extraneous items that can be left at home. And of course, your suitcase needs as much spare space as possible for souvenirs to bring home!
