Will booking a return flight for 90 days cause issues at Thai immigration if I initially plan to stay for 60 days?

Traveling from the US to Thailand on a 60-day visa is common, but concerns may arise when booking a return flight for 90 days. Generally, Thai immigration is lenient and likely won't ask about a return ticket at entry. However, airlines may require proof of onward travel within 60 days, and their policies can vary. It is advisable to check with your airline regarding their rules on return flights beyond the initial 60-day visa period.
