If you ask me, i would never go for QR or EY. They have the worst service for my liking, EY the gud aircraft but they donot provide a limo service on destination where i travel often. Further more EK's FFP is a lot better then EY's or QR's FFP.
EK has at times not lived up to my expectation but EY and QR have not even reach my expectation. Anyhow that my point, gud luck with QR.
