The complete checklist for keeping track of a trip
This is not a packing list. Nobody ever stood in an airport unable to remember what socks are. This is about the confirmations, addresses and numbers that vanish at the exact moment somebody official asks for them.
What goes missing on a trip is almost never a thing. It is a number.
The booking reference, the address in the local alphabet, what time check-in actually starts.
Before a trip, the important details arrive by email, by message, in an app, as a screenshot and as a photo of a bit of paper. Then you land somewhere with no signal, a queue behind you and a form to fill in, and you are scrolling a camera roll of 900 photos looking for a number. The fix is not more organisation. It is one page holding the ten things that matter, made before you leave and readable with the internet switched off. The checklist below has five blocks, your ticks stay put if you close the tab, a toggle adds the extra items for travelling with children, and it prints on one sheet.
The trip checklist
Saved in your browser · nothing is sent anywhereWhat actually goes missing
Ask anybody about a trip that went wrong and you will not hear about a forgotten jumper. You will hear about the booking that was under somebody else's name, the address nobody could pronounce to a taxi driver, the insurance number that lived in an email in an account that needed a code sent to a phone with no signal.
The pattern is always the same. The information existed, and a month ago you could find it easily, on a laptop, with wifi and no pressure. Then you urgently needed it and could not.
That is why packing lists do not help here and why this is a separate job. Packing is about objects, and objects are in front of you. This is about information, and information is invisible until you need it.
What has to work with the internet switched off
Sort everything into two piles by asking one question: if my phone had no signal right now, would this still be readable?
Booking references, the address of where you are staying, check-in time, passport and insurance details, the number to ring if something goes wrong, and the map of the area around where you sleep.
Restaurant ideas, museum opening hours, that article about the neighbourhood. All genuinely useful, none of it needed in a queue, all of it replaceable by asking a human being.
Most trip folders are the second pile with a couple of items from the first mixed in. Turning that round is most of the work, and it takes about fifteen minutes at a kitchen table.
Two details that catch people out. Save the address in the local language as well as yours, because a taxi driver reading a transliteration is a coin toss. And know how to reach your booking without an app, since apps want to log in and logging in wants a code sent to a phone that may be roaming.
The one page rule
Twenty screenshots are worse than one page, and it is worth being clear about why, because the screenshots feel like preparation.
WHAT MOST PEOPLE HAVE
Twenty images in a roll of nine hundred. Not searchable, not sorted, and every one needs opening to find out what it is.
WHAT WORKS
One screen. Readable in a queue, sendable to whoever you are travelling with, no login required.
Screenshots are fine as raw material, and taking them is a good instinct. Spend ten minutes copying the useful lines out of them into one place, and the screenshots become a backup rather than the plan. If you keep them, rename them: "IMG_4471" is not information, "hotel-checkin-time" is. One more thing worth knowing, since this page is about being offline: a screenshot in your camera roll usually syncs to the cloud, and some phones will happily show you a low-resolution placeholder when there is no signal. A note stored offline, or paper, does not do that.
One real page, filled in
Four nights in Lisbon, two adults, flying on a Thursday. This is the whole thing, and it took eleven minutes.

GROUND Airport to flat: metro red line to Alameda, change to green

Ten lines. Every one of them is a thing you cannot look up in a queue, and none of them needs an app to open.
| What you have | Where it should live | Who gets a copy |
|---|---|---|
| Booking references, addresses, times | The one page, offline and on paper | Everyone travelling, plus one person at home |
| Insurance number and emergency line | The one page | Everyone travelling, plus one person at home |
| Door codes and key box numbers | Your phone only, not the shared page | Nobody else, unless they are arriving separately |
| Passport scans and photos | Encrypted or password-protected storage, not a chat | Nobody by default. Take it out only if a desk asks |
| Medical details and prescriptions | The one page if a child or a condition needs it, otherwise your phone | The adults responsible, and nobody else |
| Restaurant ideas and articles | Wherever you like, online is fine | Anyone |
The part most travel advice skips. The page you are about to send to four people should not contain the door code to the flat you are sleeping in, and it should not contain a full passport scan. Group chats get forwarded, phones get left in taxis, and a message from March is still sitting in somebody’s cloud backup in November. Keep the sensitive two or three items on your own device, share the rest freely, and if you must send a document, send it and then delete the message once it has been used.
If the phone goes. Assume it will, for ten minutes, and see what breaks. Can somebody else in the group open the page? Do you know the name of the place you are staying without looking, well enough to say it to a driver? Is there any cash at all? A paper copy in a different bag answers all three, which is why it keeps coming up.
The five blocks, and what each one is really for
- Documents. Passport, visa, insurance, anything with an expiry date. The block with the most expensive failures and the fewest items, so do it first and never do it in a hurry.
- Getting there. Flights, trains, transfers, seat and baggage details. The block that changes most often, which is why the reference number matters more than the screenshot of the times.
- Where you sleep. Address, check-in and check-out, the door code, who to contact. The one people assume they will remember and never do.
- Money and staying reachable. Cards that will work, a backup, roaming or a local sim, how you will get online at all. Quietly the block that ruins days.
- Plans on the ground. Anything already booked and paid for, with its own time and address. Loose ideas do not belong here, they belong in the fine-to-look-up-later pile.
Send the one page to whoever you are travelling with and to somebody staying at home. Then three people have a copy, which beats any app, and it costs one message.
Travelling with children adds a different kind of item
Switch the toggle on the checklist and a handful of extra lines appear. They are worth calling out because they are not simply more of the same.
- Every child needs their own documents. If one parent is travelling without the other, some countries want a signed consent letter from the parent staying behind, and some want it certified. Check the rules for your destination on its own government site, weeks ahead, because the desk is a bad place to find out.
- Medical details stop being optional. Allergies, medicines and doses in the names used where you are going, plus your doctor’s contact and the insurance emergency number. Written so another adult could read it out. This is the single item most worth having offline.
- Timings become constraints. Check-in at three with a toddler awake since five is a fact worth knowing before you book the early flight, not after.
- One bag of things that must not go in the hold. Not a packing point, an information point: whoever is not carrying that bag needs to know what is in it.
Afterwards, keep about five things
The trip ends and the folder becomes clutter within a fortnight. Before it does, there are a few things worth keeping, because next time you will want them and will not remember.
- What you actually used. The transfer that worked, the place you ate twice. Not the twenty you saved and never visited.
- What went wrong and why. One line. The taxi from the airport is a scam, the check-in was really at four. This is the note that pays for itself.
- Anything with a number on it. Receipts you might claim, insurance references, tickets you may need to prove you held.
- The one page itself. Next time you copy it and change the details, which turns an hour of preparation into fifteen minutes.
Then delete the rest, including most of the screenshots. They were working notes and their job is over.
The obvious questions
"My airline has an app, is that not enough?"
For the flight, usually yes, right up until it wants you to log in on a phone with no data. Apps are excellent and they are a single point of failure. The reference number written somewhere plain is the backup that costs you ten seconds.
"Is paper not a bit much?"
One sheet of paper has a battery life measured in years. Keep it in the bag you are not going to lose.
"What about all the other travel checklists?"
They are mostly about packing and they are mostly fine at it. ClickUp collects templates, checklist.com has a general one, Upgraded Points covers packing thoroughly. If you want to know what to put in the bag, use those. This page is about what you will need to read once the bag is already packed.
The best discussion we found of the documents side specifically is a thread on the Rick Steves travel forum about carrying documents virtually: community.ricksteves.com.
Where we come into it
dEssence is somewhere to put the confirmations, screenshots, addresses and notes for one trip in one place, so that the one page has a home rather than living in a chat with yourself. Later you ask Tracy the way you would say it out loud, along the lines of what time is check-in, and get the line back instead of scrolling a camera roll.
What it is not: it does not read your email, it does not connect to airlines or booking sites, and it needs a connection, because it is a web app. That matters more on this page than usual, so keep the critical lines offline as well. Paper still wins in a queue in the rain.
You will not lose the suitcase. You will lose the booking reference.
Five blocks, one page, sent to somebody else before you go.
How the checklist works
Your ticks stay put. They are saved in your browser so you can fill this in over a week rather than in one sitting. That means they live on this device only: nothing is uploaded, there is no account, and clearing your browser data clears the list. The clear button wipes it too.
The children toggle adds items rather than replacing them, and turning it off hides those items again without losing what you ticked elsewhere.
The print button produces a one-page version with the article, the buttons and the illustrations stripped out, so you get the checklist and nothing else. Print it to paper or to a PDF, both work.
The items are ours. They come from the pattern of what people report losing rather than from any study, and the list is deliberately about confirmations and numbers rather than packing. Add your own in your head: the tool does not have custom items, which is a real limitation of a page like this.
