It used to be that cab drivers at Suvarnabhumi would ask for 500 THB as an all-inclusive number for the trip into town but the last couple of times, in Fall 2024 & January '25, I have been quoted 600 THB instead. Also, going back more than 10 years, it seems like every Bangkok taxi was a Toyota Camry. On my last trip from BKK, I realized that the cab was an anonymous Chinese sedan which sort of looked like a Camry.
