For a leisure or business trip abroad. Assumes roughly eight weeks;
with less time, do the phases in order — the first two contain
everything with a real lead time.

## Eight weeks before

- [ ] Check that every passport is valid six months past your return date `{essential}`
  Many countries deny entry inside the six-month window, and airlines
  enforce it at check-in. Routine renewals can take 6–8 weeks —
  expedited costs extra and still takes weeks.
- [ ] Check visa and entry requirements for every country on the itinerary `{essential}`
  Including layover countries — some require transit visas. Check your
  government's country pages, not the airline; e-visas and travel
  authorizations (ESTA, ETIAS-style) can take days to weeks.
- [ ] Book a travel clinic visit for vaccinations `{when: developing-country}` `{essential}`
  Some vaccines need multiple doses weeks apart, and proof of yellow
  fever vaccination is an entry requirement in parts of Africa and
  South America. Ask about malaria prophylaxis while you're there.
- [ ] Verify each child's documents and consent paperwork `{when: traveling-with-kids}` `{essential}`
  Children's passports expire in 5 years, not 10. A parent traveling
  without the other should carry a notarized consent letter — border
  agents do ask.
- [ ] Check your destination's travel advisories and local laws `{essential}`
  Some common medications (ADHD stimulants, codeine) are controlled or
  banned abroad; you may need a doctor's letter or advance permit.

## Four weeks before

- [ ] Sort out how your phone will work abroad
  Options, cheapest first: local/travel eSIM, carrier international
  plan, roaming default. Confirm your phone is unlocked before betting
  on an eSIM.
- [ ] Notify your bank and confirm your cards work abroad
  Ask about foreign transaction fees (often 3%) and confirm you have at
  least one Visa or Mastercard — Amex and Discover acceptance is thin
  in much of the world. Carry two cards on different networks.
- [ ] Get a small amount of destination currency or plan your first ATM stop
  Airport exchange desks are the worst rate in the country. A bank ATM
  in the arrivals hall is almost always better.
- [ ] Buy travel insurance that includes medical evacuation `{when: long-trip}` `{essential}`
  Domestic health insurance rarely covers you abroad, and an evacuation
  can run six figures. Buy soon after booking — some benefits require it.
- [ ] Refill prescriptions to cover the whole trip plus a buffer `{essential}`
  Keep medications in original labeled containers in your carry-on.
  Insurers often need an override to fill early for travel — call ahead.
- [ ] Enroll in your government's traveler registration program
  For US travelers, STEP (Smart Traveler Enrollment Program) — the
  embassy can reach you in an emergency and you get alerts.
- [ ] Book intercity transport and must-do activities that sell out
  Trains in Europe and Japan, and timed-entry sights, are cheaper and
  available further out.

## One week before

- [ ] Make two sets of copies of passport, visas, insurance, and itinerary
  One paper set packed separately from the originals, one digital set
  in cloud storage you can reach from any device. Add card issuer
  phone numbers.
- [ ] Check in for your flight and confirm passport details match the booking `{essential}`
  Name mismatches between ticket and passport can mean denied boarding
  — fix them with the airline now, not at the counter.
- [ ] Arrange for mail, plants, pets, and an emergency house contact
  Give a neighbor or friend a key and your itinerary. Pause deliveries
  rather than letting them pile up visibly.
- [ ] Prepay bills that come due mid-trip `{when: long-trip}`
- [ ] Download offline maps, translation packs, and entertainment
  Do it on home wifi. Google Translate and map apps both work offline
  if you download the country pack first.
- [ ] Pack, with prescription meds and one change of clothes in the carry-on
  Checked bags misconnect on international itineraries more than
  domestic. Weigh the bag — international overweight fees are steep.
- [ ] Pack plug adapters and a universal charger
  Check both plug shape and voltage; most phone chargers are dual
  voltage (100–240V), hair dryers usually are not.
- [ ] Pack snacks, entertainment, and a spare outfit per child in the carry-on `{when: traveling-with-kids}`
  Also confirm car seat and stroller gate-check rules with the airline.

## Departure day

- [ ] Do the final house sweep: trash out, dishwasher run, thermostat set, doors locked
  Unplug small appliances; leave one light on a timer.
- [ ] Confirm passports, wallet, phone, and chargers are on your person `{essential}`
  The pat-down check: passport, phone, wallet, keys. Everything else
  is replaceable at the destination.
- [ ] Leave for the airport three hours before an international departure
  International check-in and bag-drop cutoffs are earlier than
  domestic — often 60 minutes — and are strictly enforced.

## On arrival

- [ ] Get local currency from a bank ATM and decline dynamic currency conversion
  When a terminal offers to charge you in your home currency, always
  choose the local currency — the "convenience" markup runs 5–10%.
- [ ] Activate the eSIM or local SIM and text your itinerary contact
  Confirm you can receive the bank's verification texts before you
  need them.
- [ ] Note the address and phone number of your embassy or consulate
  Also save your accommodation's address in the local language for
  taxi drivers.
- [ ] Set medication times against the new time zone
  For time-critical medications, work out the new schedule once,
  on paper, instead of improvising dose by dose.
