AirAsia Group Bhd's Malaysian unit will only allow fully vaccinated adult passengers on its flights as it prepares to resume domestic and eventually international flight services, it said.

“AirAsia Malaysia has made it mandatory for only completely vaccinated adult guests to be allowed to board its flights, effective immediately,” it said in a statement, adding that those under 18 who have yet to be fully vaccinated will need to be accompanied by innoculated family.

The budget airline's Covid-19 mitigation plan is among the strictest in the industry, Reuters reports.

Australia's Qantas last month said it will require international flight passengers to be fully vaccinated while earlier this week Air New Zealand also announced the same requirement for passengers on international flights.
