Aer Lingus has confirmed that it will be opening its first base outside the island of Ireland at London's Gatwick Airport.
The airline says it will initially base four planes at the airport from next April, to serve eight routes. The routes are to Malaga, Munich, Nice, Vienna, Dublin, Knock, Faro and Zurich.
Aer Lingus says it expects to increase the number of planes based at Gatwick to eight within 12 months.
It says more than 120 jobs will be created in an investment of more than £100m.
Gatwick will be Aer Lingus's second base outside the Republic of Ireland, after Belfast.
