EasyJet generated $118 million in sales proceeds for the disposal of the remaining A321 aircraft.
The low-cost carrier agreed to sell the four aircraft in the summer 2010 but the sale closed during EasyJet's financial year which ended 30 September 2011.
The four aircraft powered by V2533-A5 engines are among the seven it inherited through the acquisition of GB Airways in 2008.
According to Flightglobal's Ascend database, MSNs 1869, 2462 and 2682, which were built in 2002, 2005, 2006, respectively, were sold to Airbus Financial Services.
The remaining aircraft, MSN 3106, was sold to Mihin Lanka but was acquired by Air Lease Corp in June this year through a purchase and leaseback transaction.
At 30 September 2011, EasyJet operated 204 aircraft comprising 167 A319s, 35 A320s and two 737-700s.
A further 35 easyJet specification Airbus A320 Family aircraft deliveries are planned for arrival over the next three years, which will be offset by 24 planned exits from the fleet. Two addtional A320 Family aircraft are also planned to be delivered as part of a GB Airways commitment.
EasyJet also holds 73 A320 family aircraft purchase options and rights until 2015.
Aircraft capital expenditure is estimated at $623 million in 2012 financial year ending 30 September. Pre-delivery payments will account for $72 million, new deliveries for $551 million.
