Can I use a bus ticket to satisfy onward travel requirements when entering Thailand with a 60-day visa exemption?

When entering Thailand with a 60-day visa exemption, travelers often query whether a bus or train ticket can serve as their onward travel proof. While the rules are somewhat ambiguous and can vary by airline, many have reported that bus tickets, such as from Hat Yai to Penang, Malaysia, have been accepted. However, the final decision typically rests with the airline being used, as they may have specific policies regarding onward travel documentation. Travelers are advised to confirm with their airline to avoid any potential issues at check-in.
