Do I need a return ticket for visa exemption when flying to Thailand?

When traveling to Thailand on a visa exemption, it is generally required to have a ticket out of the country. This ticket does not need to be a return to South Africa, but should be to a destination outside of Thailand. Many airlines will check for this ticket before allowing boarding, and it is advised to have it ready. While some travelers report not being asked for a ticket by immigration upon arrival, having an onward ticket is still a requirement that can potentially lead to denial of entry.
