Thailand had announced an extended a ban on international passenger flights until the end of June as new cases in the country dwindle.
The Civil Aviation Authority’s ban extends a previous order that was set to run until the end of May.
The announcement comes as the country begins to relax local restrictions after reporting single-digit increases of infections from new coronavirus this month.
On Sunday the government allows malls and department stores to reopen and also shorten a night-time curfew by one hour from 2200 to 0400 to 2300 to 0400.
The aviation regulator first introduced the suspension of international flights in April in a bid to curb the spread of the coronavirus.
Thailand has reported a total of 3,025 cases of the coronavirus and 56 fatalities.
