Is an onward flight necessary for entry into Thailand?

I wasn't asked

I’ve never ever been asked to show onward travel however the airline can ask at check in. I guess I’ve been lucky over the last 15 years

Usually more issues with the airline not immigration I flew KLM on a 90 non o visa with no issues and no onward ticket

Unfortunately there is not a right or wrong answer

My mate comes in on 1 way tickets all the time , never a problem.

They sometimes ask for proof of money 💰 to stay .

An open ticket these days can cost as much as buying a new ticket to change dates, and as my mate doesn't know when he will return he buys a single in and a single out .

I have never had to show a onward flight.

Yes

Airline will probably want to see an outward flight.

No

Yes

Just makes it easier.

Most airlines want to see or you won't get on the plane. Or immigration may also ask your plans to leave again $10 buys a onward ticket reservation

Flew from Scotland with Qatar, I had flexible return ticket initially for 6 months , the agent said she sees I have a return ticket booked but what were my plans as it’s 6 months away . I had booked a cheap flight to Cambodia after reading advice on here. I might still have got away with it but not entirely sure. At Bkk I was asked by immigration officer what my plans were in Thailand . I told her that travel in Thailand and to Cambodia and other Asian countries. Never asked for onward ticket but it was nerve wracking as the people I travelled with all had return tickets within 3 to 4 weeks and sailed through . This is my first time in 5 years coming back to Thailand. My flight landed early hours on a Sunday and although immigration busy it flowed ok. The main concern I think is the airline

Just buy cheap disposable onward ticket.

Google onward ticket.

Better safe than sorry.

Always had it when entering on a stamp but never asked.

Don’t play, departing airline can refuse you boarding.

I was asked for one.

Book for US$ 14 on

Then you have one

Depends on officer and your country travel history. Better have it

Yes, no, it depends … on what type of visa (or exemption) you are entering by.

As a tourist, yes.

Read the rules on entry

Not needed but it's good to have

Been 15 times over last ten years never got asked once. 4 times in the last 18 months

Thai authorities formally require tourists to have a return or onward ticket from Thailand in order to enter the country by air. Although proof of this ticket is not usually requested at the immigration control of entry to Thailand, it is recommended that you comply with this requirement in any case.

Not as strict as in Malaysia, for example, where a return or onward ticket is a must. All airlines bound for Malaysia will request this requirement when checking in. No return or onward ticket you will be denied check in.

Just say you are doing a land border crossing and going to Cambodia

Yes.

No and if it did come down to them telling you that you must have one then you just have to book one and show them and pay the boss some money so he can fulfil his destiny of getting free money from tourist. He will be happy and you’ll be allowed in. That’s the worst so don’t worry about it.

You do not need a flight to exit thailand as you can exit via land to it's neighbouring countries. Just tell them you are going to cambodia, laos, or Malaysia by vehicle.

It's very hit and miss - I've been asked several times for my outbound flight at passport control. Other times, they stamp you right in. I'd personally have an outbound flight booked within the required time frame, even if it's a cheap flight to somewhere nearby like Vietnam. Nothing is guaranteed - but I'd recommend to err on the side of caution.

If you are traveling as a tourist (tourist visa or visa exempt) then legally you are required to have proof of onward travel within the number of days you will receive upon arrival (60 days). Realistically, immigration only asks for this when they are looking for a reason to deny you entry, so it's very rare.

But it's very common for your airline to ask you for this, and if they ask you cannot provide it, they will not let you board your flight. You will need to contact your airline and ask them about their policy.

Usually required for the airline to board

Yes

It is possible to enter without one.

It is possible to get refused boarding without one.
