Cuba Carry-On Essentials: What to Keep With You

Checked 11 October 2026. This is a practical carry-on guide, not an airline baggage allowance chart. Cabin size, weight, security screening and entry requirements depend on your route and carrier.

Before committing to a trip: check Canada’s current Cuba travel advisory. As of this review, Canada advises avoiding non-essential travel because shortages and service disruptions can affect transport, electricity, food, water and medication. Conditions and flights can change.

1. Keep entry documents together—and available without Internet

Use a slim document pouch that you can reach without opening the whole bag. Bring:

• Your passport and any visa or eVisa information required for your route.
• Your D’Viajeros confirmation and QR code, saved as a screenshot or PDF and printed when possible.
• Proof of travel medical insurance, including the emergency assistance telephone number.
• Flight details, hotel or casa address, and your confirmed airport transfer contact.
• A return or onward booking if relevant, plus emergency contacts on paper.

For Canadian travellers, official entry advice distinguishes some direct-flight packages from journeys via a third country. Do not assume your visa is included. Check the airline and Cuban requirements for your exact itinerary. The D’Viajeros form can be completed within the permitted pre-arrival window; keep the resulting QR code accessible at check-in and arrival.

Never make your only copy a link in email or a cloud drive. Open the saved files in airplane mode before leaving home.

2. Pack medication for delays, not just the flight

Put essential prescription medication, inhalers, glasses, contact-lens supplies and other necessary medical items in your cabin bag. Keep prescriptions in labelled packaging and bring documentation when appropriate. Plan an extra supply for a reasonable travel delay with your pharmacist or care provider.

Canadian airport security allows essential liquid medication above the usual 100 ml limit, but you must present it for inspection. Cooling packs needed for medicine may also qualify for an exemption. Discuss refrigeration, battery-powered devices and airline arrangements before the trip rather than improvising at the airport.

Medicines and medical supplies may be difficult to replace in Cuba. A suitcase delay is not the moment to discover that all your treatment is in the hold.

3. Separate your arrival cash and payment backups

Keep enough accessible cash for the first transfer and immediate needs, with the remainder stored securely and discreetly. If you carry more than one card, do not store them all in the same wallet. Save your bank’s lost-card number offline.

Card acceptance and ATM availability can be unreliable, especially during power cuts. Do not rely on an airport cash machine as your only plan. For more detail, see backup payment methods for Cuba.

4. Prepare a phone that still helps when the network fails

• Charge your phone fully and carry the right cable and wall charger.
• Download offline maps covering the airport, accommodation and nearby streets.
• Save the hotel address, transfer driver’s details and essential numbers in notes and on paper.
• Save booking confirmations and entry documents directly on the device.
• Test everything in airplane mode. A screenshot is often more dependable than a live app.

Take a power bank only if it meets your airline’s current lithium-battery rules. Never leave a power bank in checked baggage. International aviation guidance updated in March 2026 limits passengers to two personal-use power banks and prohibits recharging the power bank during flight; your airline may impose additional limits. Check the watt-hour label and the carrier’s policy before travel. If your cabin bag is taken at the gate for the hold, remove power banks and spare batteries first. See the IATA passenger guidance and the site’s power-bank guide.

5. Build a small first-night kit

Think of what you would actually need if the checked bag arrived the next day:

• Clean underwear, a light outfit and sleepwear.
• Toothbrush, travel-size toothpaste, deodorant and any essential hygiene products.
• Glasses or contact-lens essentials, sunscreen and insect repellent in permitted sizes.
• Baby supplies or special-diet items needed during travel, if applicable.
• A compact snack for long connections and an empty reusable water bottle to fill with safe drinking water after security.

For departures through Canadian security, regular liquids, aerosols and gels must generally be in containers of 100 ml or less inside one clear, resealable 1 L bag. Medically necessary liquids and certain infant supplies have exceptions. Review the CATSA rules and the rules at any connecting airport. Check Cuban import restrictions before bringing food; do not assume that every snack or fresh product is admissible.

6. Organize the bag for the airport and arrival

Top or outside pocket: passport, boarding information and document pouch. Easy-access compartment: medication and security-screening liquids. Protected compartment: cash reserve, electronics and power bank. Bottom: first-night clothes and toiletries.

Keep your cabin bag within the airline’s actual size and weight allowance, including on connecting flights. A personal item and a cabin suitcase may have different rules. Put your name and a reachable contact inside the bag without exposing sensitive information on the outside.

Common mistakes to avoid

• All documents on one phone: a dead battery or lost device can block access. Carry a printed fallback.
• Medication in checked luggage: keep the treatment you need with you.
• Power bank in the hold: remove it if your cabin suitcase is gate-checked.
• Full-size sunscreen at security: pack an approved travel size or place a larger container in checked baggage.
• Assuming every payment card works: prepare a realistic cash backup.
• Assuming the flight or transfer will run normally: recheck your route and transfer close to departure.

What if your checked bag does not arrive?

Before leaving the airport, report the missing bag to the airline or its baggage agent, obtain a reference number, and confirm how delivery or collection will work. Photograph your baggage tag and keep receipts for essential replacement purchases in case your insurance or airline requests them. Contact your accommodation and transfer provider if the delay changes your plans.

Your carry-on should let you manage the first night without urgently searching for medicine, money or a charger. For the full process, read what to do when luggage is delayed or lost in Cuba.

Carry-on questions travellers ask

Should I put all my cash in my carry-on?

Keep cash with you rather than in checked baggage, but divide it discreetly between secure places you control. Do not display the full amount in public.

Can liquid medication exceed 100 ml?

Essential medication can be exempt at Canadian checkpoints. Keep it accessible, labelled and ready to show screening staff. Check the rules for any transit airport too.

Can I bring a power bank on the plane?

Usually yes, in cabin baggage and within the applicable limits. Check the airline’s latest restrictions on number, capacity and in-flight use. Never put it in a checked suitcase.

What if I have only a personal item, not a cabin suitcase?

Prioritize documents, medication, cash, phone, charger and a compact hygiene kit. Choose clothing only if it fits within the carrier’s personal-item allowance.

Do I need paper copies if I have everything on my phone?

Paper backups are strongly recommended for the D’Viajeros QR code, accommodation address, insurance and emergency contacts. They are useful during outages or if your phone fails.

Final five-minute check

Passport and entry documents? Medication? Cash? Offline addresses and QR code? Charger and permitted power bank? First-night basics? If yes, your carry-on is doing its job. It is a practical safety net—not a second full suitcase.
