The LTN-LCA has been operated since the demise of AJet (Helios)
As for the aircraft orders, XL France have 3 A320's & the 2 A330 ordered, XL Germany have 2 A320's on order. As they are now all part of the same group I'm sure they will all be swapped around as necessary.

2 of the 767-300's are apparently going back to the Leasing Company soon, and the contract on the 743's comes to an end in 2008, hence the orders for the A330's.
