EasyJet will serve eight European destinations from its new base at London Southend Airport when it opens in April 2012.
The carrier will launch flights to Amsterdam, Alicante, Barcelona, Belfast, Faro, Ibiza, Malaga and Majorca.
EasyJet announced in June that it would base three Airbus A319s at Southend from April 2012.
The airport, which was acquired by Stobart Group in late 2008, secured government approval in March 2010 to extend its 1,605m (5,265ft) runway by 300m to enable it to accommodate Boeing 737 and Airbus A320 aircraft.
Southend is located on the UK's southeast coast and has rail links to London's Liverpool Street station.
