Thailand Visa Exemption Confusion: Does the Two-Entry Limit Apply to Flights?

Thailand’s revised visa-exemption rules took effect on 15 September 2026, but official Thai embassies are currently publishing different guidance about one important question: does the new limit of two visa-exempt entries per calendar year apply only at land and sea borders, or does it also apply when arriving by air?

There is also renewed confusion over an older rule referring to a maximum of 90 cumulative days within six months. Next Step Hua Hin checked current official sources to separate what is confirmed from what remains unclear.

What is confirmed from 15 September 2026?

Thailand’s Ministry of Foreign Affairs confirms that the revised visa-exemption and Visa on Arrival schemes took effect on 15 September 2026. Under the main visa-exemption scheme, ordinary passport holders from 60 countries and territories can enter Thailand for tourism without obtaining a visa in advance, with a permitted stay of up to 30 days.

The complication concerns repeat entries.

Helsinki says the twice-a-year limit applies to land and sea borders

The Royal Thai Embassy in Helsinki gives very specific guidance. Its current visa-exemption conditions state that entering Thailand through land or sea border checkpoints under the Tourist Visa Exemption Scheme is permitted only twice in a calendar year, with stated exceptions for nationals of Malaysia, Brunei Darussalam, Indonesia and Singapore.

This is consistent with the interpretation that the numerical two-entry cap is a border-crossing restriction rather than a blanket limit on all visa-exempt arrivals.

London says only twice per calendar year

The Royal Thai Embassy in London uses broader wording. Its announcement says eligible passport holders are allowed to enter Thailand under the Visa Exemption Scheme only twice within a calendar year. It does not limit that statement to land or sea crossings.

Oslo explicitly includes air travel

The Royal Thai Embassy in Oslo goes further. Its current page states that Norwegian and Icelandic passport holders travelling to Thailand by air, land or sea are eligible for the Visa Exemption Scheme a maximum of twice in a calendar year.

That directly conflicts with the narrower land/sea wording published by the Helsinki embassy.

What about the “90 days in six months” rule?

Another official page has caused fresh discussion. The Royal Thai Embassy in Wellington updated its visa-exemption page on 22 September 2026 and the page contains wording saying visa-exempt travellers who leave and re-enter Thailand may stay for a cumulative period not exceeding 90 days within six months from the date of first entry.

However, this should not be treated as evidence that Thailand introduced a new 90-days-in-six-months rule in September 2026.

The same wording appears in an older Ministry of Foreign Affairs visa Q&A that was last updated in November 2022. This strongly suggests that the Wellington page contains legacy explanatory text alongside the new 2026 visa information.

So can you fly into Thailand visa-exempt more than twice a year?

At present, we do not think travellers should be told categorically either that all air arrivals are capped at two per calendar year or that repeated visa-exempt air arrivals are unlimited.

The official guidance is inconsistent. Helsinki specifically describes a land/sea restriction, while London uses a general twice-per-year limit and Oslo explicitly includes air arrivals.

Who actually decides whether you can enter Thailand?

There is an important distinction between issuing a visa and granting permission to enter Thailand. Royal Thai embassies and consulates, under the Ministry of Foreign Affairs, process applications and issue visas. They do not make the final decision on admission at Thailand’s border.

The Ministry of Foreign Affairs itself states that Thai embassies and consulates have authority to issue visas, while the authority to permit entry and determine the permitted stay rests with immigration officers. This means that even a traveller holding a valid Thai visa can be refused entry if an immigration officer determines that the person falls within a prohibited category under Thailand’s Immigration Act.

That distinction is especially relevant to the current conflicting embassy guidance. Embassy websites are important sources for visa requirements, but Immigration is the authority applying Thailand’s entry rules at the border. Ultimately, an immigration officer decides whether a traveller is admitted and for how long.

Immigration discretion at the border

There is also an important distinction between a fixed numerical entry limit and the authority of an immigration officer at the port of entry. The London embassy states that immigration officers may request additional documents and conduct an interview. Admission under visa exemption should therefore never be regarded as automatic simply because a traveller has not exceeded a numerical limit.

What should frequent visitors do?

Travellers making occasional holidays to Thailand are unlikely to be affected by this uncertainty. The issue is much more important for people relying on repeated visa-exempt entries to spend extended periods in Thailand.

If you expect to enter Thailand repeatedly, particularly if your travel pattern could look more like long-term residence than tourism, it is sensible to consider the appropriate visa rather than relying on consecutive visa-exempt stays.

Next Step Hua Hin previously reported on the confirmed two-entry limit at land borders. We will update this article if the Immigration Bureau or Ministry of Foreign Affairs issues central guidance clarifying whether the new two-entry limit also applies to arrivals by air.

Bottom line

The 30-day visa-exemption scheme from 15 September 2026 is confirmed. A twice-per-calendar-year restriction is also appearing in official guidance, but Thai embassies are currently describing its scope differently.

The older “90 days within six months” wording has resurfaced on an embassy website, but we have not found evidence that it represents a newly introduced September 2026 rule.

Until Thailand’s central authorities provide further clarification, frequent travellers should avoid assuming that repeated visa-exempt entries—whether by air, land or sea—will automatically be granted.
