Thai holidays in September and what they do to fares

September 2027 has no Thai public holiday on the Bank of Thailand list, and Thai schools are in session until the October break. That makes it the quietest month for outbound Thai demand, and fares to Europe drop after the European summer ends.

Demand comes from elsewhere instead. Japan's Respect for the Aged Day (third Monday) and Autumnal Equinox Day fall in September under Japan's holiday law and can form a long weekend; Korea's Chuseok and China's Mid-Autumn holiday also fall in September or early October depending on the lunar calendar. Check those dates before booking Japan, Korea or China.

Visa notes for Thai passport holders in September

These are the entry rules for the places this page recommends. Rules change, so confirm on the official page before you pay for flights.

• Schengen countries (most of the EU plus Norway, Iceland and Switzerland): Thai passport holders need a Schengen visa, and since the Entry/Exit System started, fingerprints and a face photo are taken at the first border crossing. https://travel-europe.europa.eu/ees_en
• Japan: Thai ordinary passports are visa-exempt for short stays of up to 15 days; a longer trip needs a visa from the Embassy of Japan. Immigration rules: https://www.moj.go.jp/isa/index.html
• Turkey: check the current rule for Thai passports on the official e-Visa system before booking. https://www.evisa.gov.tr/en/
• Anywhere else on this page: check the country's embassy in Bangkok or its official e-visa portal, starting from the Thai Department of Consular Affairs. https://consular.mfa.go.th

Weather and crowds at a glance in September

When to book for September

• September is a good month to buy Europe at shorter notice, but the Schengen visa still sets the lead time: allow for the appointment and processing before buying non-refundable flights.
• For Japan, Korea and China, avoid the local holiday weeks unless the festival is the reason for going; outside them, September rooms are often cheaper than October's.
• Hong Kong and Taiwan trips in September need a flexible return: the Hong Kong Observatory's typhoon signals can close the airport and businesses for a day.
• Buy and install the eSIM at home in the days before departure; most plans in our catalogue only start counting days on first connection at the destination, which the plan page states.

Data needs in September

A long Mediterranean trip, the classic September shape, often runs Italy into Greece or Portugal into Spain. Check that a regional plan covers both countries; if the trip is mostly one country, its own plan plus a small second one can be cheaper. Ferry days between islands use little data but coverage at sea is patchy, so download tickets before boarding.
