The carrier will add services to Bucharest, Eindhoven, Tenerife, Lanzarote, Warsaw and Vilnius from Gatwick, its first base outside Ireland, which opened in April.
Its current flights to Dublin, Faro, Knock, Malaga, Munich, Vienna and Zurich will continue, but Nice will cease during the winter months.
With the addition of the new routes, Aer Lingus will operate 118 round trips a week from Gatwick.
The airline’s corporate affairs director, Enda Corneille, commented: ‘Aer Lingus’s European destinations are still proving to be a huge hit with our customers.
‘Since our first launch back in April, we have sold over 400,000 flights and counting.
‘To give our customers a greater choice in destinations, we’ve introduced six new routes which are popular to travellers during the winter months - perfect for anyone looking to escape the British winter.
‘We are still competitively priced, as well as making life a little easier for customers with free allocated seating, self service check-in kiosks, web check-in and onboard service that puts our competitors to shame!’
The six new destinations went on sale today (9 June), and will be available for travel from 25 October, with the exception of Vilnius, which commences on 10 September.
Sample one-way fares incorporating taxes and charges include £24.99 for Eindhoven, £29.99 for Warsaw and £49.99 for Tenerife.
