Carry-on packing checklist

Pack the first night as though your checked bag might arrive tomorrow.

A small cabin-bag essentials layer cannot prevent baggage delay, but it can protect medicine, documents, valuables and the first change of clothes while the airline traces the suitcase.

Reviewed 1 September 2026

01

Start with items that are difficult or unsafe to replace

Keep travel documents, keys, prescription medicine, fragile valuables and irreplaceable personal items out of checked baggage wherever airline and security rules allow. A delayed-bag expenses claim may not make the disruption harmless.

Carry prescriptions in appropriate packaging and check destination rules for controlled medicines before travel.

02

Build a simple first-night layer

Choose compact, ordinary items rather than using the checklist as a reason to buy a second wardrobe. The goal is resilience with minimal cabin space.

  • Underwear, socks and a lightweight change of clothes.
  • Travel-size toiletries that comply with departure security rules.
  • Phone cable, plug and any essential device adapter.
  • Basic sleep or comfort items that are genuinely useful on arrival.

03

Keep spare lithium batteries and power banks in the cabin

IATA passenger guidance says spare batteries and power banks must be carried in cabin baggage, protected against short circuit and kept within applicable capacity limits. Smart luggage with a charging battery may need that battery removed before the suitcase is checked.

Check every operating airline because cabin-size, weight and battery acceptance can differ.

04

Use organisers without hiding what security needs to inspect

Packing cubes can separate the change of clothes from electronics, while a toiletry bag can keep compliant liquids together. Do not overfill the cabin bag or make security screening unnecessarily difficult.

An organiser is convenience gear, not a baggage-protection system. Keep the checked-bag tag receipt, photographs and PIR process separate.

Common questions

What passengers ask next.

What should I pack in hand luggage in case my suitcase is delayed?

Prioritise medicine, documents, keys, valuables, chargers and a compact first change of clothes, within airline and security rules.

Should power banks go in checked baggage?

No. IATA guidance says power banks and spare lithium batteries belong in cabin baggage and must be protected against short circuit, subject to capacity and airline limits.

Will the airline reimburse everything I buy after a delay?

Not automatically. Purchases should be necessary, reasonable and evidenced. Check the airline's current policy and keep itemised receipts.

Do packing cubes stop baggage from getting lost?

No. They organise contents but do not change airline tracking, handling or claim rights.
