Shannon Airport has reopened after heavy fog forced it to close late last night.
The airport closed at 11pm last night and reopened at lunchtime today. It expected a number of flights to be delayed as a result.
Ryanair flights to Stansted, Liverpool, Edinburgh, Malta, and Porto were all impacted as well as Aer Lingus services to London.
Two Aer Lingus services from New York and Boston due into Shannon earlier this morning were diverted to Dublin.
A spokesperson for The Shannon Airport Group said that as a result of unexpected heavy fog during a period of essential taxiway maintenance work, Shannon Airport temporarily closed at 11pm yesterday.
A later statement said: "We are pleased to announce that Shannon Airport has now reopened and resumed normal operations as of 1pm."
"We anticipate there will be some disruptions to the flight schedule throughout the day, and we regret any inconvenience this may cause to our passengers," said the spokesperson.
Passengers traveling today are advised to check with their airlines for up-to-date information on their flights.
"Our airport staff and airline partners will continue to work to minimise any further delays or disruptions, and we appreciate your understanding at this time," added the spokesperson.
