The carry-on-only traveller moves faster, cheaper and calmer. The trick is a repeatable system so you're not reinventing your packing list every trip.

The essentials, always in your bag

  • Passport / ID, boarding pass, and a backup photo of both on your phone.
  • Cards, some local cash, and a spare card kept separately.
  • Phone, charger, and a power bank.
  • Any medication — in your carry-on, never checked.
  • A change of clothes and toothbrush (in case of delays).

Clothes: the rule of 3s

For a short trip: 3 tops, 2 bottoms, enough underwear for the trip plus one, one layer, one pair of versatile shoes on your feet. Pick a single colour palette so everything mixes.

💡

Roll, don't fold

Rolling clothes saves space and reduces creases. Packing cubes make it even tighter.

Liquids: the 100ml rule

  • Containers of 100ml or less, in one clear resealable bag.
  • Buy toiletries at your destination if it's a longer trip.
  • Solid alternatives (bar soap, solid deodorant) don't count as liquids.
⛔

Don't pack these in hand luggage

Full-size liquids, sharp objects, and anything you'd hate to lose to a security bin. When unsure, check the airline's list.

Checklist

The mistakes that get you a checked bag anyway

Most people who pack a carry-on well still get caught out at the gate. It's rarely the weight — it's the shape and the timing. Here's what quietly forces your bag into the hold:

  • Overstuffing the outer pockets. A bag that fits the sizer flat won't fit once you've crammed a jumper and a water bottle into the front. Pack the mains, then the pockets.
  • Boarding in a late group. On full flights the overhead bins fill fast and gate staff start gate-checking bags for free. Board earlier and you keep your bag with you.
  • Ignoring the airline's personal item rule. Budget carriers often let you bring only a small under-seat bag for free, with the cabin bag as a paid extra. Check which size you've actually bought.
  • Wheels and handles count. The sizer measures your bag including them. A 'cabin-sized' case can still be a centimetre over.
💡

Wear your bulk

Your heaviest, bulkiest items don't count against your bag at all if they're on your body. Wear the boots, the coat and the chunky jumper through the airport — you can always stuff them in the overhead once you're seated.

Frequently asked questions

Can I bring an empty water bottle through security?
Yes — the 100ml liquid rule only applies to what's inside. An empty bottle goes through fine, and you fill it at a fountain past security. This saves you buying overpriced airport water and keeps you hydrated on the flight, which matters more than most people think on longer journeys.
Do I have to take electronics out of my carry-on?
It depends on the airport's scanners. Older lanes want laptops and large tablets out in a separate tray; newer CT scanners let you leave everything in. Pack them near the top so they're easy to grab if asked, and you won't hold up the queue fumbling at the belt.
How do I stop my clothes creasing in a carry-on?
Roll soft items like t-shirts and jeans rather than folding — it saves space and resists hard creases. For a shirt or blazer, lay it flat across the top and fold once, or interleave it with rolled clothes so nothing gets a sharp bend. A quick hang in a steamy bathroom sorts the rest on arrival.
What if my bag is slightly too big at the gate?
Stay calm and try the sizer yourself first — squashing the pockets flat often buys you the extra centimetre. If it genuinely won't fit, ask whether gate-checking is free; it usually is, and your bag comes off at the carousel or plane door. Worst case it's a fee, so keep valuables and meds on you, not in the bag.
Can I pack a razor in my carry-on?
Disposable and cartridge razors are fine in the cabin. Loose double-edge safety-razor blades and straight razors usually aren't — pack those in a checked bag or leave them home. An electric shaver is always allowed. When unsure, put the item somewhere you can reach it so security can inspect it quickly.
