China Southern To Add Winglets To 737NGs

In the original order of 737 Next Generations, China Southern Airlines did not have Aviation Partners Blended Winglets installed. However, the airline has opted to install winglets on 40 737NGs.

Seen above, is China Southern's 737-81B, B-5190 (c/n 35366, l/n 2223), that was delivered in March 2007 without the Blended Winglets.
