It's that time of year again - thousands of people are making the journey home and away for St Patrick's Day.

Dublin Airport says it is getting ready to welcome more than 370,000 passengers arriving and departing in the coming days.

Musical entertainment, festive decorations and 'greening' of Terminals 1, 2 and the original 1940s building will add to the festive atmosphere.

"This is our third year to green the airport and we're lighting up more locations around the airport campus bringing the St Patrick's Day festival to life at the airport", DAA spokesperson Siobhán O'Donnell said.

This is also a big sporting week at the airport.

Some 20 flights have been added to the schedule for the thousands of punters travelling to and from Cheltenham, as well as Scottish fans arriving in for the last Six Nations rugby match next Saturday.

Passenger numbers are up 17% to just over 3.4 million for the first two months of the year.

Dublin Airport is advising passengers to check which terminal their flight is departing from before leaving home.

Aer Lingus, Etihad Airways, Emirates and all the US carriers operate from Terminal 2 - while all other airlines operate from Terminal 1.

Passengers should plan to arrive at least 90 minutes before their flight, irrespective of whether they are checking in from home or at the airport.

And passengers are reminded that EU aviation security regulations concerning liquids are still in place.

And the airport also has this important message:

We've said it before & we'll say it again, it is not & never has been St Patty's Day. #StPatricksDay pic.twitter.com/sOsYvDJFOr
