The European Union will hold a meeting of aviation and security experts next week on the suspected plot to blow up planes that was uncovered in the UK.
Warsaw airport is one of many in the EU to see tighter security
Finland, which holds the rotating EU presidency, said the meeting was needed to discuss anti-terrorism measures.
The UK says 23 people are being held over the alleged plot to blow up several planes with liquid explosives.
France on Friday announced a temporary ban on liquids in hand luggage on flights to the US, UK and Israel.
Finnish State Secretary Kari Salmi said the meeting would be in Brussels although the exact date has not yet been set.
Mr Salmi said: "The aim is that experts will go through the situation in aviation security. Are the regulations in place? Are communications, both on EU and national level synchronised?"
A statement from the Finnish presidency said another "restricted" meeting was being considered of ministers responsible for internal security.
The suspected UK-based plot caused many delays and cancellations of flights to the UK from European airports, many of which have seen heightened security.
The UK has said its security threat level is to stay at "critical" although it believes the main suspects are in custody.
Nineteen of 24 people arrested have had their UK assets frozen. The names have been published by the Bank of England.
One of the 24 was released without charge on Friday night.
On Friday the world's top money laundering watchdog, the Paris-based Financial Action Task Force, urged nations to increase measures to combat the financing of terrorism.
Alain Damais, its executive secretary, said: "This is again a kind of wake-up call for all the countries around the world."
It is thought that the suspects were planning to blow up several planes by using liquid explosives carried in soft-drink bottles, and detonators disguised as electronic equipment.
Searches are continuing at UK addresses
On Friday, the French prime minister's press office said that France was implementing a temporary ban on liquids, creams and gels in hand luggage, in addition to measures already in place aimed at ensuring the safety of French citizens and transiting passengers.
UK police said the planned explosions could have caused "mass murder on an unimaginable scale".
Officials in Pakistan said security forces in the country had arrested two British men of Pakistani origin in connection with the alleged plot.
They were picked up from Lahore and Karachi last week.
On Thursday, Pakistan announced it had made a number of arrests in connection with the investigation.
The UK Home Office has refused to confirm reports that Thursday's anti-terror operation was triggered by the interception of a decoded message sent by a suspect in Pakistan, which gave the go-ahead for the attack to take place.
The suspects were rounded up in raids in London in Buckinghamshire and the West Midlands. All are being held in London.
Searches continued at several addresses.
