The concession was announced by CCSA assistant spokeswoman Apisamai Srirangson this afternoon (Jan 14), reports the Bangkok Post.
Dr Apisamai said 30% of the approved Test & Go travellers had arrived before the New Year, and this rose to 50% during the New Year holiday.
The government earlier suspended the one-night quarantine Test & Go entry programme indefinitely as Omicron variant infections began to spread rapidly.
However, previously approved Test & Go registrants were allowed to continue arriving, and the deadline was extended from Jan 10 to Jan 15.
“Previously approved travellers can still arrive after the Jan 15 (this Saturday) deadline. The CCSA at its next meeting will consider additional measures,” Dr Apisamai said.
Officials were monitoring the condition of arrivals in this group, as well as those in the Sandbox entry programme. They would ensure that infections did not overload the local health system, she said.
