A total of 1.9 million passengers passed through Dublin, the 9% rise being driven by significant upturns in volumes to and from continental Europe (+7%), the UK (+8%) and North America (+28%).
The number of passengers using Dublin Airport as a hub to connect to another destination increased by 45% with almost 55,000 passengers connecting through the Irish gateway last month.
Meanwhile in Sweden, airport operator Swedavia reports that its January upturn in passengers was driven by a 13% rise in international traffic at Stockholm Arlanda, which ensured that 2.8 million travellers passed through the nation's 10 gateways last month.
“More and more people are choosing to fly to and from our airports, which shows how crucial air travel is for Sweden’s growth," enthuses Jonas Abrahamsson, president and CEO of Swedavia.
"When we look at passenger volume over the past twelve months, we are really close to the historic 40 million mark."
January's figures mean that 39.7 million passengers used Sweden's airports in the year ending January 31, 2017.
Swedavia predicts that if the current levels of passenger growth continue, over 40 million people may pass through its gateways in 2017.
