I have been to Thailand about 12 times on 90-day tourist visas and 2 times on retirement visas over 12 years As recently as March 2024 I arrived at BKK airport and was given a 30 visa-exempt. entry, 3 weeks later I went to Thai Immigration at "Blupoint Shopping Centre" in Hua Hin and obtained a 1-month extension for Bt1900, it took about an hour all told including the interview with a police officer. I have never been asked about a ticket to exit Thailand on all my trips. In the 15 times I have been there, I have never been asked about an exit ticket even though it says you will.
PS... I now have a ticket to return to Hua Hin on 18/09/2024, exiting Thailand on 14/11/2024 which is 57 days. For me, it does not matter if they have not sorted out their 60-day visa-free entry issues by then. If not I'll get 30 days visa-free stay and just apply for 30 days extension at Immigration in Hua Hin and pay the required Bt1900.
By the way, Thai Immigration was/is very helpful at Hua Hin Immigration with staff people eager to advise you of the method and offer help, it is much simpler now. You only need your passport and proof of where you live to fill out the application (best to do a dry run first)). i.e. a receipt from your hotel will do. Thailand by delaying each application for the 60 visa-free issues is then Bt1900 better off, when you extend your visa, I don't mind, I believe tourists should/could be required to pay something.
