Do airlines or Thai immigration require travelers to show a bank statement or cash for entry into Thailand?

The discussion focuses on whether travelers have been asked for a bank statement or proof of funds upon arriving in Thailand. Most respondents indicate that it is rare for airlines to request financial documentation, and while Thai immigration is allowed to ask for 20,000 baht in cash, this rarely happens unless the traveler has been previously flagged. Many users share their experiences, noting that travelers from certain regions, like South Asia, might encounter such inquiries more frequently. Additionally, some mention the possibility of showing a bank statement or bank app but emphasize that the formal requirement is cash.
