St. Patrick's Day is obviously a massive day for the country, but today has an added importance.
The Irish rugby team are just a win away from completing a first Grand Slam since 2009.
England stand in their way this afternoon at Twickenham, eager to shatter Irish dreams, and avenge last years 4 point loss in Dublin.
Thousands of fans are making the trip across the water for the match, and Aer Lingus had a special treat for passengers aboard their flight yesterday.

"In the unlikely event that you forgot to pack your kit, we ask that you stay calm and take a moment to locate the Ireland jersey located in the seat pocket in front of you."
A nice gesture from the airline, on Ireland's biggest day.
