Nearly 30 flights have been impacted this week with bomb threats being made and aircrafts being diverted.
After an Aer Lingus flight was diverted to France due to a bomb threat, 21 flights total were impacted over the course of the day.
The incident took place on November 5, with seven other aircrafts being impacted on November 3 for similar threats.
The escalation in the number of threats is a cause for concern for many people, but it is also unclear if any of the November 5 threats were from the same group or copycats.
When speaking to Newstalk Breakfast, Kevin Byrne, a retired lieutenant colonel and airport safety and security auditor, revealed that officials have now shared how the bomb threats are being made and specifically how the Aer Lingus one came in.
He shared: "In the case of the Aer Lingus one, I understand it was sent by email to the air traffic services in France. This is done in a very sophisticated way.
"There may be copycats because we had seven on Tuesday and now 20-something yesterday, which amazed me. Every time I went to the phone or looking at the news, it got bigger and bigger.
"So this is organised. It's done remotely. I think it's done by a state actor with other people involved in it to disrupt and upset us.

"What they do is they look at a flight the day before, decide what they're going to do, and about 20 or 30 minutes after the aircraft takes off, they send a remote message, either by telephone...
"Of course, you can get bots to do this. So you have an American accent making the call. You have a burner phone. You won't be checked.
"Or you can use an email address, which, of course, is very difficult to trace. And they've done that repeatedly yesterday.
"And doing it both ways means it muddies the waters a wee bit. There are no special codes because nobody has claimed responsibility.
"So the finger is quite hard to point at anyone. But it's very effective, very cheap and it's done in lieu, I think, of using drones to upset the operations of airports, which were a feature in Europe and, indeed, Ireland last year.
"So it's a new and dangerous phenomenon. But thankfully, nothing has been found."
The Aer Lingus plane was travelling from Dublin to Rome and landed safely at a French Military base in Evreux.
When speaking to The Claire Byrne Show, Paris-based journalist John Litchfield said that the fact the diversion was announced by the Prime Minister's office indicated that the country was taking the threat very seriously.
Aer Lingus released a statement to Lunchtime Live on the diverted flight which reads: "Flight EI402 from Dublin to Rome diverted to Normandy this morning as a security precaution. The flight landed safely.
"Aer Lingus will work to reaccommodate those customers to their final destination as soon as possible."
