Will my airline allow me to board with a return ticket after the visa-free stay in Thailand is reduced to 30 days?

Call your airline to make sure, but it's most likely "Yes".

While everybody's in a "panic", not much has really changed except 60-to-30 days, and tighter enforcement.

There's no indication a routine 30-day extension won't be granted for a legitimate tourist.

That said, the "60-day" price is now aligned.

Visa-exempt/free entry + 30-day extension, roughly 1900 Baht.

60-day Tourist visa, roughly 1900 Baht, and NO trip to Immigration for the extension, but some pre-trip paperwork, AND no worry at the airline counter. LOL

One thing for utterly certain is that the semi fake "onwards tickets" are going to be examined closely at check in

Even I've ditched them for a genuine airline ticket for next trip

The reality is we don't know because nobody has tried it yet.

We'll find out on the 15th.

I booked my flight for 51 days, long before the approval of reverting 60 days to 30. I am in the same position as yours, now workin' on gathering alk documents to apply for single entry tourist visa.

To answer your question, i emailed airline and asked about this situation if i'll be denied boarding if i dont have 60-day visa. They told me to call Thailand embassy and ask about it. On their side, they wouldnt deny me boarding but Thai immigration might deny me entry upon landing

Then i emailed Thailand embassy and ask the same exact question. They answered i should ask the airline itself and my very own immigration BEFORE leaving homecountry because i MIGHT get denied boarding and stamp out.

I went to my immigration (close to my home) and personally presented this case and showed them email responses of airline and Thai embassy. Guess what the guy said! He told me they have no power to hold me off boarding just because my return flight is over than visa exemption.

Neither sides can be trusted at this point and i do not want to take my chances being denied boarding for the ticket i had paid since January, also i do not want to risk being denied entry into Thailand. Hence, $50 tourist visa and a bit of hasle with required documents

What dates are you travelling

I would say Yes

There will be many ,

Many people in the same position as yourself

You can do 30 days + extend for 30 in Thailand to get up to 60 days if needed

Just get yourself a 60 day tourist visa 👍🏻

A question for your airline

Only you airline can answer that question
