Airport security is being increased at European airports after the United States called for heightened precautions amid reports two terror networks are working together on a bomb that could evade existing measures.
The extra security measures have not been disclosed, an are not expected to cause “significant disruption” to passengers.
The Dublin Airport Authority said there will be no direct effect on passengers for the moment and what is being requested is a secondary search for US-bound travellers.
Irish airports are liaising with the Department of Transport on the issue.
It is believed the extra measures could include extra screening of footwear and electronics, and additional bomb-detection devices.
Changes were announced after Washington Homeland Security Secretary Jeh Johnson ordered beefed up security at foreign airports from where aircraft fly directly to the US.
US officials were reported to have said the move was the result of intelligence that groups in Yemen and Syria had joined forces to plot an attack.
