The current plan for summer 2010 is a reduction in the fleet from 44 to 40 aircraft. 4 A320s are leaving, but one will be replaced by a leased A320 or A321 (no news on where from yet), so a net loss of 3 there. The scandinavian A330-300 will not be based in the UK next summer so 1 less A330 (7 rather than 8 last summer).
G-JMCF (B752) will be replaced by G-DIMB, the 767-300 returning from lease with Monarch in April.
