Lion Air, Indonesia, suspends all flights after passengers fail to comply with coronavirus rules

As airlines across the globe attempt to restart travel in the wake of coronavirus slowdowns, not all things are going according to plan.

In Jakarta, Indonesia, Lion Air announced that all domestic and international flight operations would be suspended temporarily beginning June 5. The move was made, in part, because travellers not following the requirements of the country's COVID-19 health protocols, according to the airline's website.

In a statement, the airline said the "decision was based on considerations from an evaluation of previous flight operations, that many prospective passengers were unable to carry out air travel because they did not complete the required documents and conditions" necessary during the country's pandemic alert period.

Passengers who have already purchased tickets will be able to receive a full refund or change their ticket without fees when travel resumes, but for now the airline's stated goal is to prioritise the "physical and mental health conditions of all employees."

Last month, Indonesian President Joko "Jokowi" Widodo issued a ban on mudik, the annual exodus of millions of travellers from the country's cities at the end of the Ramadan fasting month, according to reporting from the Jakarta Globe. The Transportation Ministry allowed for business-related travel and family emergencies, as long as travellers could show proof they were free of the coronavirus, but few met the requirements.

"Many passengers had to cancel their trip because they could not show the required documents," a spokesman for the airline told the paper after the airline reopened earlier this week.

Indonesia - a country with a population over 267 million - was hit hard by the coronavirus outbreak, and millions of its residents have been under sweeping travel restrictions and stay-at-home orders for months.

According to data from the country's Central Statistics Agency, domestic flight volume was down 82 percent in April, with 838,100 passenger on flights, compared with 4.6 million in March. International travel numbers were worse, with a 95 percent drop in passengers leading to 26,000 fliers last month as opposed to 558,700 in the month of March.

Lion Air has promised to monitor the coronavirus outbreak to keep the company's "flight operations under applicable provisions of safety and security aspects," and to "continue to implement health protocols according to the provisions" that prevent the spread of COVID-19, but for now there's no date set for when air travel will resume.
