Do I need an onward flight ticket when flying with Emirates to Thailand for a retirement visa?

Correct

Or cancel and get 50% refund.

ok then you can get a ticket and just forget it when you get into Thailand

@Luit ****************

yes, for the Extension of Stay

@Pat *******

Cheapest one here is 655 baht

About 18 USD

@Pat *******

the airline will indeed always say yes. It's a strange misconception by the senior members in this group who keep advising to ask an airline about their enforcement policy.

The reason they'll always say yes is slightly different though: they are supposed to check this and a check is always possible if the check-in crew has time/feels like doing it. On the phone they cannot promise that you can get away with breaking the rule, they'll always tell you what's officially required.

Look to the answer of Stuart Chiverton.

@Pat *******

how would it generate more money for them? If you're only buying an onward exit ticket.

@Pat *******

same airline but different airport may be a different answer so just ask the airline

@Pat *******

get an onward ticket for $10 from bookingforvisa.com It's $10 vs the uncertainty/hassle if they ask.
