What about ME? They have a very young fleet which they always advertise as the youngest. Their A321s and A332s are all new and they've only had them for a few years, but i'm not sure if its only for 4 and a half years like 9W
. Maybe BA
or Airxliban have the info?
As for Etihad, I believe that they operate some aircraft that are not new, such as a 767 if I am not mistaken. Ex A6-SUL, now A6-EYZ:
Also, one of their A332s, A6-EYY, shows that an Airbus A330-223 (same type) with the same c/n (238) was with TAM before, although I am not sure if this is only a mistake or if it is true. I haven't looked at the others, but from what I see I doubt they are new.
