The travel day to a resort is the one day a trip can go wrong in ways you cannot fix with money. A bag that arrives late, a flight that changes, a medication left in the hold or a phone that dies in an unfamiliar airport can each cost hours. Your carry-on is your insurance against all of them. This guide sets out what to put in it, and why, so that the first day of your holiday does not depend on your checked bag.
Documents and money first
Everything that would stop you from travelling or entering the country belongs in your carry-on, never in checked luggage. That means your passport, any visa or travel authorisation, boarding passes, your booking confirmation and the resort’s address and phone number. Keep digital copies on your phone and in an email to yourself, and carry one printed set in a separate pocket. Entry rules change, so check the official government site for your destination in the week before you fly. We have covered recent changes such as Saint Kitts and Nevis requiring an electronic travel authorization, which shows how easy it is to miss a new requirement.
Carry cards and cash on your body or in a bag that stays with you. Our guide on cash, cards and currency on a resort trip explains how to split them sensibly.
Medication and health items
Pack all prescription medication in your carry-on, in its original labelled container, along with a note from your prescriber if the drug is controlled or unusual. Some countries restrict medicines that are routine at home, so check the rules for your destination before you go. Our guide to carrying and declaring prescription medication on a resort trip explains how to check. Add a small basic kit for the first day: pain relief, plasters, any allergy medication and motion sickness tablets if you need them. Liquids in carry-on bags are limited in volume by airport security rules, so check the current limit with your airline and departure airport.
A change of clothes and swimwear
If your checked bag is delayed, a change of clothes and swimwear in your carry-on lets you start your holiday anyway. Pack one outfit, underwear, swimwear, a light layer for cold cabins and a pair of comfortable shoes. A resort pool is usually the first place you will want to go. Many airlines deliver a late bag to your hotel within a day or two, but the timing is not guaranteed. Our article on lost luggage or a missed connection and what to do before you reach your resort covers the steps to take at the airport, including filing a report before you leave the baggage hall.
Power and connectivity
Pack a phone charger, a spare cable and a power bank. Airlines restrict spare lithium batteries to carry-on bags, so a power bank must travel with you in the cabin, not in the hold. Take a plug adapter if your destination uses a different socket type. Our guide to power adapters and voltage explains the difference between an adapter and a converter. If you plan to use an eSIM, set it up before departure, as described in eSIM for a resort trip: what to check before you rely on one.
Small comfort items
- An empty reusable water bottle to fill after security.
- A pen, because arrival forms still need one in some airports.
- Snacks, in case a delay leaves you without food.
- Sunglasses and sun protection for the transfer.
- A light bag for the beach so you do not unpack your carry-on on day one.
Things to leave out
Do not carry anything you cannot afford to lose into a crowded arrivals hall. Leave unneeded jewellery at home. Avoid packing bulky items in your carry-on that you may be forced to check at a full gate. If your airline has strict size rules, measure your bag at home against the airline’s published limits.
Before you leave the house
- Check your passport validity against your destination’s rules.
- Confirm your flight details and the transfer arrangements with the resort. Our guide to how included airport transfers actually work at an all-inclusive resort explains why a late arrival can affect your pickup.
- Check weather and storm risk if you are travelling between June and November. See traveling during hurricane season.
- Take photos of your documents and luggage.
Our take
Pack your carry-on as if your checked bag will not arrive, because on some trips it will not. If it does, you have simply carried a few extra items. If it does not, your holiday starts on time anyway. Airline and security rules differ between carriers and airports, so confirm your own limits before you pack.
