Can I return to Thailand with a return flight to the UK after using my 2-month visa exemption?

The user is seeking advice on entering Thailand under a visa exemption, planning to return from Bali and then apply for a TDAC while intending to show a return flight to the UK for the third month. The comments highlight that onward travel for a visa exemption must usually be within 60 days, and while Thai Immigration may not always check documents, airlines often verify flight details and can potentially deny boarding without proper onward travel arrangements.
