Worried you’ll forget something important before leaving? This travel checklist before you go covers ID, health, insurance and safety, starting about six months out for international trips and a few days out for short ones.
This checklist is one piece of broader regional travel planning, so use it alongside your route and budget decisions.
| Checklist item | Timing or figure |
|---|---|
| Call a travel clinic for an appointment | 6 months before you travel |
| Visit a travel or primary care clinic | 4-6 weeks before you travel |
| Pack prescription medications | 2-3 weeks before you travel |
| REAL ID enforcement for U.S. domestic flights | Began May 7, 2025 |
| TSA fee for travellers without an acceptable ID | $45 |
The timing comes from the Minnesota Department of Health and the ID details from TSA’s REAL ID page. Rules and fees can change, so check each source before you rely on the figures.
Which documents belong on a travel checklist before you go?
Start with identification, because a missing or wrong ID can end a trip at the airport. For flights within the U.S., TSA’s REAL ID page says enforcement began May 7, 2025. Look at your driver’s licence: the page asks whether it has a star (and/or flag) or says “Enhanced”.
If your licence does not qualify, you have two routes. TSA’s identification page says passengers should travel with an acceptable alternative form of ID, like a passport, or enrol for a state-issued REAL ID. The REAL ID page also carries an alert that travellers without an acceptable form of ID must pay a $45 fee.
Children are handled differently. According to the same TSA identification page, children under 18 are not required to provide identification when travelling within the United States, but you should contact the airline about its own rules for travellers under 18.
For international trips, passport validity is the usual trap. A 2014 WTOP report said the State Department recommends passports be valid for at least six months beyond your travel date. That article is old, so confirm the rule for your destination with the country’s official entry requirements before you book.
Gather these before anything else:
- Photo ID or passport, checked for expiry and for whether it suits the trip.
- Any visa or entry permit your destination requires.
- Booking confirmations for transport and lodging.
- Insurance policy numbers and a phone number to call.
- Emergency contacts, kept both on paper and on your phone.
Keep copies of key documents somewhere separate from the originals, such as a secure cloud folder or with a trusted contact. If a bag is lost, a copy saves hours.
When should you book health appointments and sort medicines?
Health tasks have the longest lead time, so they come first on any international checklist. The Minnesota Department of Health notes that some vaccines need to be given several weeks to months before travel, which is why its timeline starts early. It also says that even frequent travellers should stay updated on necessary medications and vaccinations.
Its timeline, in order:
- 6 months before: find and call a health care clinic or travel clinic for an appointment, and ask your insurance whether it will cover the medications and vaccines your trip needs.
- 3 months before: make the travel clinic appointment now if you haven’t already.
- 4-6 weeks before: visit your travel clinic or primary care clinic, and make sure you have medications that will last the whole trip plus medical documentation if needed.
- 2-3 weeks before: pack your prescription medications, an emergency first aid kit and emergency contact information.
A domestic weekend away does not need a six-month runway. The sensible short-trip version is to refill prescriptions, check you have enough for the days away plus a small buffer, and pack your first aid basics. If you take regular medication, carry it in your hand luggage rather than a checked bag.
What should you check on insurance and bookings?
Read what you have already bought before buying more. The Texas Department of Insurance says some credit cards include travel protections or offer travel insurance, so ask when you use the card for trip expenses. It also advises checking your health plan to see whether it would cover medical expenses if you got sick or hurt on your trip.
The same page lists several points to compare across policies:
- Cancellation reasons: some policies only cover trips cancelled for certain reasons such as weather or illness.
- Exclusions: policies may exclude cancellations due to a preexisting medical condition or if an epidemic or pandemic is declared.
- Cancel for any reason: you can pay more for this coverage.
- Medical evacuation: some policies cover it, and it can be costly depending on where you’re visiting.
Then look at what each booking already allows. The same Texas page suggests checking the cancellation policies for each item you’ve booked in advance and working out how much money you’d be out if you had to cancel all or part of your trip. A flexible hotel can make a cheap non-refundable flight less risky, or the reverse.
Plan how you will move around once you arrive, too. Last-mile gaps, such as the final stretch from a station to a village, catch people out, and the guide on how to research local transport options shows how to close them before you leave.
How do you let someone know where you’ll be?
Tell at least one person at home your itinerary, where you are sleeping and when you expect to check in. For U.S. citizens abroad there is also an official option. Capital One’s explainer describes the Smart Traveler Enrollment Program (STEP) as a free service from the State Department’s Bureau of Consular Affairs that helps U.S. citizens abroad stay connected and aware of potential emergencies.
Participants give contact and travel details so the nearest U.S. embassy or consulate can email travel warnings and advisories, according to that explainer. You can choose to be notified about things like dangerous weather, natural disasters, health issues and civil unrest.
Setup is short. To register, you create a Login.gov account and fill in your personal information, and The Points Guy reports that the website estimates roughly 20 minutes to complete. Citizens of other countries should check whether their own government runs a similar registration scheme.
Whatever your nationality, share this much with your contact:
- Flight, train or ferry details and booking references.
- The name and address of each place you will sleep.
- Your phone number and any local number you pick up.
- The check-in times you have agreed, and what they should do if you miss one.
What goes on the last-week and departure-day list?
By the final week, the large decisions are made and what is left is small, easily forgotten tasks. Work through them in order and tick them off.
- Re-check your ID or passport is in your bag, not on the kitchen table.
- Confirm transport times and any check-in windows for flights or ferries.
- Tell your bank or card provider where you are going, if it asks for that.
- Charge devices, download offline maps and save confirmations where you can read them without signal.
- Pack prescription medicines, first aid items and chargers in your carry-on.
- Arrange for someone to collect post, water plants or feed pets.
- Leave your itinerary and emergency contacts with a person at home.
On a short trip, most of this still applies, just compressed into a day or two. If you are planning one, the notes on weekend getaway planning show how to fit these checks into a tight schedule.
On departure day, leave earlier than you think you need to. Lock up, switch off appliances you don’t need and do one last pocket check for ID, payment cards, phone and keys.
Frequently asked questions
How early should I start a travel checklist?
Show answer
For international trips involving vaccines, the Minnesota Department of Health timeline starts 6 months before you travel with a call to a clinic. For a domestic weekend away, a few days is usually enough to cover ID, medications and bookings.
Do I need a passport to fly within the U.S.?
Show answer
Not necessarily. TSA’s identification page lists a U.S. passport as an acceptable ID, and a REAL ID-compliant licence also works. TSA says the list of acceptable IDs is subject to change without notice, so check its page before you fly.
Is STEP only for international trips?
Show answer
The explainer from Capital One describes STEP as a service for U.S. citizens traveling abroad, so it is aimed at trips outside the country. It is free, which makes it a low-effort addition to an international checklist.
Should I buy “cancel for any reason” cover?
Show answer
That depends on how much you would lose and what your existing cover already includes. The Texas Department of Insurance says you can pay more for this coverage, and that some policies only cover cancellations for certain reasons. Compare the exclusions before you decide.
