Does my return flight have to be within 90 days when applying for a 60-day tourist visa for Thailand?

When applying online for a 60-day tourist visa to Thailand, the requirement for a return or onward flight is generally flexible. Most users have indicated that a flight within 60-90 days is acceptable, and some have successfully used flights booked for 89 days from their entry date. It's also noted that any onward flight out of Thailand within 60 days suffices, meaning you do not necessarily need a return flight. If needed, applicants can provide a proposed booking or an onward ticket for visa purposes.
