Do I need to show an onward flight ticket upon entering Thailand with a 30-day visa exemption?

the onward ticket service gets you a ticket to show the airline staff that you have a departing ticket from Thailand. The reservation will be canceled either within 48 hours or 14 days of when you pay the company for the ticket. These ticket services are not designed to actually fly. They cost from about $10~$40 depending on the company and whether you get a ticket for 48 hours or 14 days. You can buy a 60 day round trip ticket back home, so long as you can show you will be leaving Thailand within the time of your visa. A simpler plan for you would be to apply for a 60-day tourist visa. Then you would not need to deal with an onward flight company.

I was asked once in 7 trips to the Philippines. Always better to be ready.

Normally they don't want to see it. Mostly your airline ask for it when you check in for your first flight. The point is that the airline is responsible to bring you back, if the immigration deny entry. So... it's better to have something to show that you will leave the country. If you don't trust this dummy onward tickets (although it works), just buy a real one with cost free cancellation.

@John *******

Immigration virtually never asks to see an onward ticket - normally only if they're suspicious of you for some other reason - but it's quite common for your airline to request it upon check-in, since it is technically a requirement when entering under a visa exemption.

@John *******

yes, if they ask for it, airlines also
