Really, it was only logical since the public buses in Saigon has increased it’s fare already since January 1 to 4,000 VND. And by April or May, the taxis will follow suit increasing their fares to an additional 1,000 VND/meter. Even train fare will increase as well. Read more about it here.
I can’t really complain on the shuttle fee increase as it is still 8x more cheaper than to ride a cab to work.
