Options were placed quite some time ago when -300s were on such amazing discounts. TC Germany recently announced plans to park 6 x 757-300s in the desert. Should TC UK ever decide to use more 757s they would not need options outside the group.
There is no current plan to take another A330 onto the fleet.
I know that it is tempting to believe rumours when they coincide with preconceptions and wishes; for years I believed in the generosity of human nature, because I wanted it to be true.
