Can I enter Thailand without a return ticket?

For most countries these days and onward ticket to anywhere is required within the 30 days or however long the visa is. It's not always immigration but the airlines because I have been asked in the past year going into Thailand and I am a retiree from US.

Rent one from

for 10 to $15usd and you'll receive it within an hour and just choose a popular city so they'll be lots of choices to reserve you a temporary flight and then they will cancel it within the day or so after it's date. Saves you the hassle and waiting for a refund.

Whatever company you use, be sure they say it has an actual PRN number which is your booking number so that if anyone in the rare event checked, it would show as legitimate. This company does and so do some others. But do print ticket separately so no one sees the email that it comes from or download it on your phone as a separate document.

Avoid burning season in Northern Thailand and other parts of Asia:

March through May?

Yes

Yes. As long as you have a ticket out to anywhere.

For what it’s worth, the airlines ask for the onward ticket to protect themselves from the cost of having to return you to your starting point if the destination country rejects you. In most cases, if the airline asks to see an onward ticket, you can offer to sign an indemnity against the costs of taking you back. That has always worked for me, though it never came up re Thailand.

Airlines out of Australia are asking for a onward ticket out of the country you are travelling to. It is not difficult to manufacture one using a PDF editor.

I have a US passport, am over age 60 and travel with a suitcase rather than a backpack. I’ve never been asked for an onward ticket in any of my dozens of trips to Thailand regardless of the airline and regardless of the country I’m departing from.

Use an onward ticket if you are staying more than 30 days. They are cheap last year$15 and it saves so much worry. But if you plan on leaving Thailand to go to another country within 30 days that ticket is fine.

We are from Australia and have never been asked

Been to Thailand ( and currently are now) 4 times since Covid

Yes

you need a further on ticket to another country inbetween 30 days

You 'can' enter without an onward ticket, but only if your airline's check-in crew decides not you check you. It would however be more prudent to anticipate that they do.

I travelled from Heathrow, my return ticket was dated 90 days stay , they told me 60 day was OK but not 90 they made me purchase a flight to Vietnam after the 60 day, Qatar Airlines

Go to Thailand last, otherwise you will not want to leave

The older you are the less problem you have with needing a return ticket, and that you travel with a suitcase and not a backpack. That is a stereotype if you are under the retirement visa age.

I either have a return ticket or a full fare onward ticket that is fully refundable.

Yes 🌺🇹🇭🌺

Maybe… ask your airline for 100% assurance

A return ticket is not required.

Your airline might not let you check-in to your flight to Thailand unless you can show a ticket leaving the country within 30 days though. You'll need to check what their policy is.
