Thailand pre-flight checklist: the 72-hour countdown
Everything you need to enter Thailand, arranged by when it needs to happen - from a week before departure to the moment you queue at the counter.
A week before departure
- Check passport validity - six months beyond arrival is the safe standard, with blank pages.
- Confirm your entry option: visa exemption, visa/e-Visa, VOA or eVOA - see entry options compared.
- Book or confirm your first night's accommodation - the card needs the real address.
- Keep your onward ticket resolvable - officers can ask for proof you leave within your stay.
When the window opens
- File the Thailand Digital Arrival Card on the official portal - free, one per traveller, children included.
- Copy passport details character by character; match the flight to your current booking.
- Save every confirmation email; take screenshots or prints as backup.
- Long connection? The window may open while you fly - file before boarding the last leg.
The day before
- Re-check that every traveller's confirmation exists - families, this means everyone.
- If plans changed (flight, hotel, dates), use the portal's Update Arrival Card function - or file fresh if your name, nationality or date of birth details were wrong.
- Charge your phone - the confirmation lives there.
At the counter
- Documents reachable without digging: passport, boarding pass, first-night booking.
- Still in your window but not filed? File now - it must only be submitted before you arrive.
- VOA traveller? Head to the VOA counter for the fee, then immigration - your card should already be filed.
- The officer decides entry; a correct card makes the queue fast, not guaranteed.
