Japan Airlines says it will start using a more sophisticated type of alcohol detector to test its pilots at London's Heathrow Airport.
The airline says it's been using conventional breath analyzers at Heathrow and other overseas airports. The pilots themselves are asked to monitor the testing.
In contrast, JAL has introduced a more sophisticated type of breath analyzer at all the domestic airports it operates at. This test requires that the pilots blow into a straw on the device. The system also allows test results to be sent to JAL's Tokyo office in real time.
JAL has been slow to introduce this system overseas. The airline says it will have the new devices at all its overseas destinations by the end of this month.
