Packing for Carry-On Only Travel

Elena Vasquez · May 5, 2026 · 8 min read

The case for cabin only is practical rather than ideological. You skip the bag drop queue on departure and the belt on arrival, you cannot be separated from your belongings by a misconnection, and a tight transfer stops being a gamble. On a one week trip the time saved is usually two to three hours.

Size limits are not standardised

The critical number for anyone flying low cost carriers in Europe is the free small bag. It must fit under the seat in front, and the sizer at the gate is used. A bag that has flown a dozen times on full service airlines can be rejected on its first low cost sector.

Liquids, and why the rules keep shifting

The 100 ml rule dates from 2006 and is being replaced gradually as airports install advanced computed tomography scanners. Those scanners can resolve liquids in three dimensions, which removes the need to remove them from the bag.

• Rollout is airport by airport, not country by country, and even terminal by terminal within one airport.
• Rules were relaxed at several airports, then partly reinstated, which is why travelers report contradictory experiences at the same place.
• Your departure airport may allow a large bottle while your return airport does not, so plan for the stricter of the two.
• Medications and baby food have separate provisions everywhere, but declaring them at the checkpoint speeds things up.
• Solid alternatives, shampoo bars, toothpaste tablets and solid deodorant, sidestep the question completely.

A method that works for a week or more

1. 01

   Fix the palette first

   Two neutral base colours mean every top works with every bottom. This single decision removes about a third of what most people pack.

2. 02

   Count nights, not days

   Seven nights needs roughly four tops, two bottoms and one layer, plus laundry once. Ten nights needs the same, plus laundry twice.

3. 03

   Wear the bulk

   The heaviest shoes and the outer layer travel on your body, not in the bag. On a 7 kg limit this is often the difference between passing and paying.

4. 04

   Use compression, then leave a gap

   Packing cubes work, but filling the case completely means you cannot close it after buying anything. Leave ten percent.

5. 05

   Plan one laundry point

   A launderette visit mid trip is twenty minutes and removes three days of clothing from the bag.

6. 06

   Keep the personal item disciplined

   Documents, medication, electronics, a change of clothes. Everything else goes in the main bag so the small one stays under the seat.

When cabin only is the wrong call

• Winter trips where the coat, boots and layers cannot be worn continuously.
• Any trip involving sports equipment or professional gear.
• Travel with young children, where the volume of necessary items scales badly.
• Long trips across climate zones, where you are effectively packing for two seasons.
• Routes on small regional aircraft, where cabin bags are gate checked anyway and the benefit disappears.

Gate checking, and how to avoid it

On full flights airlines routinely ask for volunteers to check cabin bags at the gate, and on very full flights they stop asking. It is free, but the bag goes to the belt at the destination, which removes the main advantage of travelling cabin only.

1. Board in an earlier group where possible, since bin space runs out from the front of each zone.
2. Keep the bag visibly compact. Gate staff select oversized looking bags first.
3. Move essentials to the personal item before you reach the gate, in case the bag is taken.
4. If your connection is short, say so. Staff will often leave the bag with you rather than risk a misconnected item.
5. Never put medication, passports, keys or electronics in a bag that might be gate checked.
