How to Pack a Week in a Carry-On: 7-Day Capsule + Compression Plan

Seven days in one carry-on works if you plan the wardrobe, do one quick wash mid-trip, and compress only the things that compress. This guide is the week-long version of our 5-day carry-on guide. It covers what to pack, how to fit it in, and the mistakes that push people into checking a bag.

Step 1: Check what your fare allows

Before you lay anything out, confirm your bag allowance. On many European budget fares the free item is an under-seat bag of about 40 × 30 × 20 cm, and a full cabin bag is a paid add-on. Our EU/UK airline cabin bag size table lists the current limits for Ryanair, easyJet, Aer Lingus, BA, Wizz Air and Lufthansa, with sources. Check your own booking too, because rules vary by fare.

Step 2: Build a 7-day capsule (the 5-4-3-2-1 formula, adjusted)

Pick one colour palette (navy, grey and one accent, for example) so every top works with every bottom. Then:

Item	Quantity for 7 days	Notes
Tops / T-shirts	4	Merino or quick-dry fabrics can be re-worn and dry overnight
Underwear & socks	4–5 sets	Wash once mid-week
Bottoms	2	Wear the heavier pair on the plane
Warm layer	1	A packable fleece or light down compresses well
Outer layer	1	Wear it to travel
Shoes	2 pairs max	Wear the bulkiest pair
Sleepwear / swim / gym	1 each, if needed	Choose double-duty pieces
Toiletries	1 clear liquids bag	Follow your departure airport’s liquids rules
Tech	Laptop/tablet, chargers, adaptor	Keep reachable for security trays

Step 3: Plan one wash

A sink wash on night 3 or 4 (travel wash or a bar of soap, then roll each item in a towel to squeeze the water out) cuts what you carry by almost half. Hotels and apartments with a washer make it even easier. This is how one-bag travellers do two weeks with the same kit.

Step 4: Pack in the right order

1. Bottom layer, things that don’t compress: shoes (stuff socks inside), toiletry bag and chargers.
2. Middle, soft clothes you won’t need until the hotel: this is where compression pays off.
3. Top / outer pockets: liquids bag, laptop, passport, medication, a layer for the plane.

Step 5: Compress the soft stuff (and only the soft stuff)

Vacuum compression is the difference between a week of layers fitting or not. It works on air trapped in fabric, so knits, fleece, T-shirts and puffy layers shrink a lot, while denim, shoes and bottles barely change. The method:

1. Fold or roll soft clothes flat and press out air by hand.
2. Close the compression compartment and use a pump to draw out the remaining air.
3. Re-pack heavy, rigid items around the compressed block.

Our Airbag Lite backpack has this built in, and the Air Pump Lite is included free (not sold separately). You press clothes down by hand, then the pump finishes the job, so you don’t need separate vacuum bags. Packed size is 48 × 32 × 10 cm. It expands for extra packing, but don’t assume the expanded bag will be accepted as cabin baggage, and check your airline. More detail: how vacuum compression packing works and vacuum cubes vs a built-in vacuum backpack.

Don’t compress: structured blazers you need crease-free on arrival (fold them on top instead), anything damp, and items you’ll need before the hotel.

Step 6: Weigh and measure before you leave

Compression saves space, not weight. A week of clothes plus a laptop can push past 8–10 kg cabin limits, so weigh the bag at home with a luggage scale or a bathroom scale. Measure it including any handles and pockets, and leave a little slack for souvenirs. Our pack more without checking a bag post covers return-trip space planning.

Airport security tips for compressed bags

Keep liquids and laptop in the top layer so you can take them out without opening the compressed section. Compressed clothing is normal through X-ray, and our airport security tips explain what screeners see.
