Channel News Asia reported Wednesday that Singapore Airlines has been taking steps to reroute the flight path since July this year. It hadn't previously announced the changes before this week.
The crew of the Cathay Pacific Airways flight says they witnessed the rogue nation's latest weapon break apart and explode as it traveled through the sky early Wednesday morning on November 29. A decision on whether its planes should avoid the Sea of Japan is also "taken every day".
Mr Wright also said the "flash" seen by Korean pilots about an hour after the missile's launch would be consistent with the warhead heating up during reentry, since the missile flew for 53 to 54 minutes. The sightings are believed to have been of North Korea's latest intercontinental ballistic missile (ICBM) test. Hwasong-15, according to North Korean state media, reached an altitude of 4,475 kilometers (2,800 miles), and put the "whole" United States mainland in its range. Mr. Trump did not give any specifics on plans to combat the North Korean threat however, the USA moved a squadron of the military's F-22 stealth fighters to South Korea to begin combat exercises following the ICBM launch.
"We have been in contact with relevant authorities and industry bodies as well as with other carriers".
A Japan Airlines spokesman told the BBC that as of Thursday, all routes were deemed "safe to operate", but they were "prepared to implement any route changes as needed". "We remain alert and (will) review the situation as it evolves".
China says Indian drone entered its airspace, crashed
An Indian drone has "invaded China's airspace and crashed" on its territory, Chinese state media said. But the mountainous border remains sensitive for both sides.
Korean Air didn't provide details of theflights that saw the "flash", or say where they were at the time of the event.
Despite the missile being close enough to be seen by the pilots, the airline is not planning to change its flying routes at the moment.
Any missile launches must be reported to the International Civil Aviation Organization to assure the safety of civilian aircraft.
It is very unlikely that a plane would be hit by a random missile, though.
The chances of a plane being struck randomly by a missile are "billions to one", according to CNN aviation safety analyst David Soucie.
