Air France has expanded the area around North Korea ruled off-limits for its planes after the country's recent missile test.
The airline said the missile apparently fell about 100 kilometres (60 miles) from the trajectory taken by Air France Flight 293, travelling on July 28 from Tokyo to Paris.
In a statement to the Associated Press, Air France said such a distance means the flight was not in any danger.
But it said that "as a precautionary measure, the company has decided to expand the non-flyover area around North Korea".
The airline said it routinely adjusts flight zones based on evolving threats, and already had a ban on flights over North Korea before the recent test.
It did not specify the scope of the new no-fly area.
