These frames have RR on the cowling. This is perhaps one reason why EK would loathe to take these aircraft, especially if they found the RRs turned out to be more efficient than the GP7200.
Or perhaps EK might not want to touch the frames after they have been associated with a company, that obviously thinks it is completely acceptable to clothe their cabin crew in such a utterly disgraceful manner!!!! Aisle seats at the rear of the cabin would be interesting.
