I bought a one way ticket to Thailand from the USA. I didn't buy a return ticket because I don't know when I want to return.
I have heard of people having problems because they did not have a return ticket.
Has anyone had a problem due to getting a one way ticket?
TLDR : Answer Summary
Many travelers have reported mixed experiences when arriving in Thailand with a one-way ticket. Some individuals, including Canadians and Americans, have stated they faced no issues, while others noted that airline policies may require proof of onward travel to prevent potential fines. Travelers often suggest purchasing a cheap 'onward ticket' to a neighboring country as a precaution. It appears that experiences can vary greatly depending on the airline and the specific immigration officer at the time of entry.
