The Travel Documents Checklist: What to Carry, What to Copy, and Where to Keep It

Nobody has ever missed a flight because they forgot their sunglasses. People miss flights because a passport expired four months early, a visa was never applied for, or the boarding pass lived on a phone that died in the taxi.

Packing lists get all the attention. The travel documents are the short list that actually decides whether the trip happens. Here is a checklist for them: what to sort out weeks before, what to have on you on the day, what to keep a copy of, and where to put it all so you can find it at the counter without emptying your bag.

Weeks before: the checks that cannot be fixed at the airport

These are the ones with lead time. Do them when you book, not when you pack.

• Passport expiry, against the return date. Many countries want your passport valid for several months beyond the day you leave, and six months is a common rule. Check the date on the passport against the rules for every country on the route, including the ones you only connect through.
• Blank pages. Some countries want one or two empty pages for stamps. A passport full of stamps from good trips can stop the next one.
• Visas and travel authorisations. Some trips need a visa, many now need an online authorisation instead, such as the US ESTA or the UK ETA. They are usually quick to apply for and impossible to get at the gate. Use the destination government's own site, not a lookalike that charges a fee to fill in the same form.
• Domestic ID. For flights inside the US, your licence needs to be REAL ID compliant, or bring your passport instead.
• Driving abroad. If you are renting a car, check whether the country expects an International Driving Permit alongside your licence. It is cheap and quick at home, and unobtainable on arrival.
• Travel insurance. Buy it early enough to cover cancellation, then save the policy number and the emergency claims line somewhere you can reach from abroad.
• Health paperwork. Any vaccination certificate the destination asks for, and prescriptions for medication you are carrying, ideally in the original packaging.

Most entry rules change from time to time, so treat any list, including this one, as a reminder of what to check, and the official government page as the answer.

The day you travel: what has to be on you

This is the list to run through at the front door.

• Passport or ID, the actual physical one. A photo of a passport does not board a plane.
• Boarding passes, in the airline app, the phone's wallet, or on paper. Having two of those is better than one.
• Visa or authorisation approval. Electronic ones are usually linked to your passport, but keep the approval email or number in case someone asks.
• Booking references for every leg and every hotel. The six-character code is what a gate agent or a front desk will ask for when anything goes sideways.
• The first night's address, written so you can hand it to a driver or type it into a landing card.
• A payment card and a little local cash, kept apart from each other.
• Insurance details and an emergency contact, reachable even if your phone is not.

Copies: what to back up, and how not to overdo it

The advice to "make copies of everything" is right in spirit and a little dangerous in practice. A scan of your passport is a gift to anyone who finds it. So copy deliberately.

• Do keep a copy of the passport photo page, the visa, and the insurance policy. If the original is lost or stolen, a copy makes the consulate visit faster.
• Keep one paper copy in a different bag from the original. Paper does not need charging.
• Keep the digital copy somewhere protected, not loose in your camera roll, where it sits between holiday photos and gets synced to every device you own.
• Share the copies with one person at home you trust, not a group chat.

The real problem is scatter, not forgetting

Most people do not forget documents. They scatter them. The flight confirmation is in one inbox, the hotel PDF in another, the rail ticket is a screenshot, the insurance policy is an attachment from March, and the passport scan is photo number 3,412. Every item exists. None of them can be found in the ninety seconds you have at a check-in desk.

So the useful habit is less about having documents and more about having two places for them:

• One plan for the bookings, with the confirmations, times, and references in date order, readable without a signal.
• One locked place for the identity documents, the passport, the ID, the insurance policy, kept separate from the plan you share with other people.

Keeping them apart matters. You want to send your travel partner the hotel address. You do not want to send them your passport number by accident.

Being fair about the tools

Airline apps are the best place for that airline's boarding pass and nothing else. Phone wallets are excellent for passes and tickets that support them, though plenty of rail and ferry tickets do not. TripIt is dependable at building a plan from clean confirmation emails and has been doing it for years. Tripsy is polished on Apple devices, and Wanderlog shines when you are still deciding where to go.

The gaps tend to show up in the same places: confirmations that are not clean email text, documents that need more protection than a photo album, and plans that need a connection to open.

Where Petrel fits

Petrel Voyage handles both halves: the bookings plan, and a separate locked place for the documents you would rather not leave lying around.

• Any confirmation format goes in. Forwarded emails, PDFs, screenshots, photos of a paper ticket, or a spreadsheet. Petrel reads them and builds one day-by-day itinerary with the booking references attached to each item. Our post on turning PDFs and screenshots into an itinerary shows how.
• The plan opens offline. Booking codes, addresses, and times are readable with no signal. To be exact: readable, not editable, so changes wait until you are back online.
• Live flight status on the flight card, so the gate and any delay sit next to the booking reference rather than in a separate app.
• An encrypted document vault for passports, IDs, insurance policies, notes, and key contacts. What goes in is encrypted on your own device, so we cannot read it. On iPhone you can unlock it with Face ID. The honest trade: the key comes from your passphrase, and there is no reset, so write that passphrase down somewhere real.
• Sharing that leaves the sensitive parts out. Collaborators are free to invite. A public share link needs no account to open and deliberately omits booking codes, costs, and receipts, so you can send the plan to family without sending your references.
• No account needed for your first trip, so you can try the bookings side on a real trip before signing up for anything.

On privacy, plainly: Petrel does not connect to or scan your inbox. You forward or upload what you choose. Your bookings are not sold and are not used to train AI. Our page on why we built it this way explains the reasoning.

The checklist, in one place

When you book: passport validity against the rules for every country on the route, blank pages, visa or online authorisation, domestic ID, driving permit, insurance, health paperwork.

A few days before: paper copy of the passport photo page, visa, and insurance, in a different bag from the originals. Digital copies somewhere locked. Copies shared with one trusted person.

At the front door: passport or ID, boarding passes, authorisation approval, booking references, the first night's address, card and cash, insurance and emergency contact.

Then put the bookings in one plan that opens offline, and the identity documents somewhere locked. You can start that plan at https://petrelvoyage.com. The first trip is free, with no account and no credit card.
