The new premium cabin actually retains the 2-3-2 layout, but with slightly more legroom and much better seats than the current fleet.
All First Choice Airways' long-haul flights for summer 2005 will be on aircraft in the new config. The new 767s will be refurbished before delivery, and the existing aircraft that is staying will be modified over the winter season into the new layout.
There will be no "second-class" long haul aircraft!
