The carrier has operated more than 22,000 flights over the past 12 months and will fly up to 800 flights a week across 30 routes by peak summer 2023.
 
This includes new flights connecting Cork to Bristol and Belfast to Isle of Man, as well as increased flights from Dublin to 14 airports across the UK.

 
The first Aer Lingus Regional domestic flight from Dublin to Donegal took off as part of the franchise partnership, 10 months in advance of the original start date which was planned to be January of this year.
 
Lynne Embleton, Aer Lingus chief executive, said: "Emerald Airlines is a key partner for Aer Lingus, as we continue to rebuild and grow our transatlantic network. The first year of our partnership with Emerald has been very positive."
 
This summer, Aer Lingus will operate its largest ever North American schedule to date, with more than 2.25 million transatlantic seats on sale for summer 2023.
