The man used his wife’s ID card and negative COVID-19 test certificate to be cleared to fly from Jakarta to Ternate on the northern island of Maluku on Sunday, said Nandang Sukarna, chief executive of the Halim Perdanakusuma airport.
The man, identified only by his initials DW, wore a full veil to board.
A flight attendant saw the man change his clothes before leaving the plane and alerted airport authorities, he said.
“His intention was just to use someone else’s negative PCR test so he could fly,” Nandang said, referring to the polymerase chain reaction test for the virus.
The man was arrested after the plane landed and was tested immediately, local media reported. He was ordered to self-isolate at home after the test came back positive.
Police have announced that they will prosecute him as soon as his quarantine ends.
Indonesia has imposed travel restrictions amid a rapid increase in coronavirus cases since last month, driven by the highly transmissible Delta variant.
As part of measures to curb the spread of COVID-19, airline passengers are required to produce proof of vaccination and a negative coronavirus test certificate before boarding flights.
Indonesia reported a record 1,566 deaths from COVID-19 on Friday, bringing the total death toll to 80,598, according to data from the country’s COVID-19 task force. It also recorded 49,071 new coronavirus infections, bringing the total number of cases to more than three million.
The daily death toll in Indonesia has steadily exceeded 1,000 since July 16.
The explosion of COVID-19 cases has overwhelmed hospitals on the islands of Java and Bali in recent weeks.
