Hi everyone, I am currently in Thailand on a DTV and need to travel domestically for a friend's family funeral. I am planning to fly from Bangkok to Nakhon Si Thammarat. Since I've read a lot about which airports are 'safer' for immigration checkpoints, I wanted to double-check: will there be any issues or visa scrutiny at the domestic terminals or at the Nakhon Si Thammarat airport? Do domestic flights face any immigration checks at all, or is it just standard ID verification? Thanks in advance!
