The seats on the 767 are more narrow, but beside this the same style like on their 777 and similar to LH/SK, while their Service and food is much better than on most competitiors in C or even F. OS will keep or increase its long haul network as its the part bringing the money!
By the way their complete long haul fleet will be refurbished with new Seats (in C similar to LX), new interior design (and colours!) and a new IFE, In addition to that their 767 will get a completely new cabin (bins, walls, lavatories) form autumn 2012.
