Steps
Lay out all the clothes you plan to take for the week. Group them into outfits or categories so you can see the real pile before any packing aid goes in.
Weigh your empty carry-on and note the limit for your airline. This tells you how much room you have for clothes and aids before the bag gets too heavy.
Fill a standard packing cube with one group of clothes and zip it shut. Keep the cube loose rather than stuffed so the fabric does not bunch into a tight ball.
Roll or fold each item flat before it goes into a compression cube. Smooth out the wrinkles first, because compression locks in whatever creases are already there.
Zip the compression cube and press the air out through the second zipper. Stop when the cube feels firm, not rock hard, so the clothes still have some give.
For bulky items like jackets or sweaters, place them in a vacuum bag and pull the air out with a pump. Seal the bag fully before you start so no air creeps back in.
Stack the cubes and bags in the carry-on with the heaviest ones near the wheels. Fill gaps with socks and small items so nothing shifts when you lift the bag.
Weigh the packed bag and compare it to your limit. If it is over, remove one cube or switch a bulky item to a vacuum bag.
Tips and common mistakes
Compression cubes save space but add weight from the zips and fabric, so weigh the bag after packing.
Vacuum bags flatten clothes well but leave deep creases, so keep wrinkle-prone shirts out of them.
Do not overfill cubes into tight balls, since rounded shapes waste the corners of your bag.
Check your airline's carry-on size and weight limits before you rely on compression to fit everything.
Questions
Do packing cubes actually save space?
Standard cubes mostly organize rather than shrink. Compression cubes and vacuum bags remove air and save more room, but they add weight and can wrinkle clothes.
Are vacuum bags good for a carry-on?
They flatten bulky items well, but the sealed bags are stiff and can leave sharp creases. Use them for soft, wrinkle-tolerant clothes like fleeces.
How do I stop clothes wrinkling in compression cubes?
Fold or roll each item smooth before compressing, and avoid packing the cube too full. Take wrinkle-prone shirts out and fold them flat on top instead.
