This page covers a direct flight to Thailand. If your route connects through a third country, that country may require its own transit visa — sometimes even for a short airside layover. Transit rules depend on your specific routing, so check the country you connect through separately, or analyse your full itinerary.
You're travelling to Thailand (TH). Your home cellular plan may or may not include data abroad — check your carrier's international options before you fly. An eSIM is a low-commitment alternative if your plan doesn't cover the destination or charges high roaming rates.
Declare USD 20,000 or equivalent when entering or leaving Thailand (TH). Form: Customs declaration. Declare USD 20,000+ or equivalent; THB 50,000+ on exit
The US State Department publishes these advisories for your route. Thailand: Level 2 — Exercise Increased Caution (as of 2025-07-25). Review the country page for the specific areas and risks flagged before you go. This is a US State Department safety perspective, not an entry or boarding rule — it doesn't affect whether you can board, only what to be aware of on the ground. Travellers from other countries should also check their own government's advisory.

Transmission is often region-limited within a country (e.g. coastal vs highland zones) and varies by season. Discuss prophylaxis with a travel medicine clinician — the right antimalarial depends on the specific region, your medical history, and any medications you take.
Thailand (TH) requires every traveller to submit the Thailand TM6 Digital Arrival/Departure Card for entry — best done a few days before departure rather than in the airport queue. Without it, expect to be pulled aside at the border or denied boarding. Digital immigration card replacing the paper TM6 form. Complete before arrival. Apply at: https://tm6.immigration.go.th/
Thailand (TH) restricts or bans the import of: codeine, psychotropic substances, some sleeping pills. The risk is real — travellers have been detained at customs for over-the-counter products that are routine elsewhere. If you take any prescription medication, look up the active ingredient against the restricted list above before booking. Always carry the prescription bottle plus a doctor's letter naming the medication and the condition it treats. Adding your medications to your profile (optional) lets us tell you specifically which of yours match. Thailand FDA approval needed for some medications; carry prescription.
Thailand requires proof you'll leave before they let you in. At check-in the airline often asks for this — without it, they can deny boarding because the carrier becomes liable for flying you back. Easiest fixes, in order: (1) book a refundable return or onward flight, (2) use a one-way bus / train ticket out, or (3) buy a temporary onward-ticket reservation through a service like OnwardTicket. Have whichever you choose printed or on your phone before you reach the counter.
Thailand (TH)'s immigration officers can ask arriving visitors to show they have enough money for the stay — some travellers are never asked, others are pulled aside at the same border on the same day, so plan as if you will be. Approximately $30/day per person. Accepted: Cash or bank statement showing 20,000 THB. Thailand requires 20,000 THB or equivalent per person Have a recent bank statement, a credit card with available limit, or a sponsor letter ready — the goal is to have a documented answer the officer can check in 30 seconds, not a debate.
Typical September conditions at BKK (Thailand (TH)): wet. Typical lows around 24°C, highs around 32°C, frequent rainfall (~296mm for the month). Expect frequent rainfall this month (~296mm typical). Pack a compact rain shell and a small umbrella.
Your passport-to-Thailand pairing isn't in our verified reference yet — coverage is expanding. Before booking, confirm the requirement directly with Thailand's official immigration portal (linked below). If a visa is needed it usually has to be applied for in advance, so don't rely on a check-in agent's word.
