Aer Lingus will launch new twice-daily flights to London Gatwick from Cork in the spring.
The airline said the route will compliment the four existing daily services between Cork and London Heathrow and will go some way to strengthening business and leisure between Ireland and south-east England.
Flights will begin on March 6th, with the first service departing Gatwick at 06:50 GMT and touching down in Cork at 08:15.
Kevin Cullinane, Cork Airport’s marketing manager, said the news is a "huge boost" for the airport.
"I am sure the announcement will be welcomed by the travelling public as well as by our region’s tourism and business communities," he explained.
"Cork Airport has always sought to provide its customers with a choice of airlines and destinations and this announcement is a further step in achieving this."
Aer Lingus has a busy flying schedule from Cork, with the airline operating year-round flights to Amsterdam, Barcelona and Berlin in addition to many others.
Last month, the Irish carrier introduced flights to East Midlands from the city, with services operating on Mondays, Fridays, Saturdays and Sundays.
