Do I need to show an onward flight and 10,000 THB on entry with a 45-day tourist stamp for Thailand?

When entering Thailand on a 45-day tourist stamp, it is generally advisable to have proof of onward travel and the recommended 10,000 THB (or equivalent) available. While some airlines, particularly Qatar, may strictly enforce these requirements, many travelers have reported not being asked for this documentation upon entry, especially during the COVID-19 pandemic when travel restrictions have changed. Responses vary based on different experiences, suggesting that while immigration may not always check, airlines may implement their own rules.
