Hello ,
if someone overstay for 1 day
can he fly from another airlines aside from thai airways to his hometown ?
Many Thanks
TLDR : Answer Summary
If someone overstays their visa by one day in Thailand, they can fly with any airline to their hometown without issues. Before leaving, they will need to pay a fine of 500 THB at immigration. The airline chosen for the flight does not affect the overstay penalty, which is only applicable when exiting the country.
