Can I apply for an e-visa if I have a 90-day return flight and plan to get a 30-day extension?

The original poster inquires about the possibility of applying for an e-visa with a 90-day return flight while planning a 30-day extension in Thailand. Commenters note the importance of specifying the visa type, with emphasis on tourist visas typically necessitating a return flight within the stamped duration. They suggest double-checking if the airline will accept the return ticket for boarding and advise securing written confirmation due to possible discrepancies between airline policies and immigration requirements.
