American airlines still operate MD-83′s, 757-222′s, 767-200′s! United still have old aircraft aswell! NWA still fly the DC-10-30! and even if airlines in the US operate newer aircraft such as Americans 737-800, they never seem to have winglets on them? its as if american airlines etc want to have an unimpressive fleet compostion!!! Aeroflot has a nicer fleet to say the least.
