Bangkok Governor Pol General Aswin Khwanmuang has been pushing for this ceiling ahead of the introduction of the Mo Chit–Khu Khot extension route.
The maximum fare is already Bt65 but there are widespread concerns that BTS fares may rise to Bt158 if the longer route opens and there is no ceiling in place.
The BTS route, also known as the Green Line, has already expanded its network significantly.
At its inception it covered just the On Nut–Mochit route and On Nut-Saphan Taksin.
But with the state’s financial support, BTS services have already extended from On Nut to Samut Prakan’s Kheha station and from Saphan Taksin to Bang Wa.
