ANA Holdings and Japan Airlines said their subsidiaries allowed workers who drive baggage cars and catering vehicles at Tokyo¡¯s Haneda Airport to cheat on written driving license exams.

A total of 78 drivers at ANA cheated on tests conducted by two subsidiaries between August 2022 and February 2024, Â鶹´«Ã½ biggest airline said in a statement. That included invigilators allowing candidates to look at textbooks while taking their exams, it said.

The airline has allowed workers who took the test again under ¡°appropriate circumstances¡± to resume their duties and vowed future exams will be undertaken appropriately, it said.

Meanwhile, JAL said it returned 11 drivers¡¯ permits to authorities after discovering they cheated on tests conducted by two subsidiaries between May 2022 and January 2024. The company, which conducted an internal investigation after receiving a report from an employee, is no longer allowing online exams.

The airline reported the incident to the transport ministry and the civil aviation bureau, it said.

Â鶹´«Ã½ aviation industry has come under increased scrutiny this year after a number of high-profile incidents. In January, a collision at Haneda left five of six crew aboard a coast guard plane dead after it was struck by a JAL Airbus jet landing on the runway. Shortly after, a Korean Airlines plane clipped a stationary Cathay Pacific Airways jet at an airport in Sapporo, on the country¡¯s northern island.
