Security has been stepped up at the Airbus wing plant in Broughton in response to the increased terror threat.
Safety measures were 'adjusted' following the attacks in Paris last week which left 129 people dead.
The aerospace giant said there had not been a specific threat to Broughton, but reiterated their 6,000 staff should remain 'alert but not alarmed'.
A bomb scare meant 200 people were evacuated at an Airbus factory in France earlier on Friday (November 20).
An Airbus spokesman said: “Security of our sites and the safety of our people has always been top priority, but given the current climate it is entirely appropriate for Airbus to adjust security measures.
“This is not, however, in response to any specific threat and we are reiterating to our staff the UK government’s advice to remain alert but not alarmed.”
In Toulouse a suspicious package was found at the plane manufacturer’s main assembly line today sparking a terror alert.
The item believed to be a box containing three cans of fizzy pop connected with wires – raised suspicions that it could be a homemade bomb.
It was found in the engine of an Airbus A330 that was still being built.
But police and bomb squad experts who arrived at the scene and examined the threat said no explosives were present.

A spokesman said: “Airbus confirms an Airbus building in Clement Ader (Colomiers 31) was evacuated as a precautionary measure following a suspected bomb alert.
“Specialist bomb disposal teams were on site to assess the situation.
“We can confirm that this security alert is now over and all our employees have returned.”
The wings made at Broughton are transported via one of the iconic Beluga planes to the site in Toulouse.
The A380 wings, which are two big to fly, are taken instead by land, rail or boat.

The Toulouse incident is the latest terror scare in Europe following the attacks in Paris last Friday.
Yesterday, a pub landlord from North Wales was caught up in the Manchester Airport bomb hoax drama.
Ed Griffiths and wife Laura, who run the Panton Arms in Pentraeth, Anglesey, had just taken their seats on the Morocco-bound easyJet flight when an announcement was made by the captain.
Ed who was celebrating his 42nd birthday, told the Daily Post how he and his wife were seated in the middle of the plane when the call was made to evacuate the aircraft after a passenger claimed to have a bomb in his bag.
Two men, aged 45 and 46, were arrested on suspicion of making a bomb hoax.
