On a 9w 73G right now and noting the above - when did they start retrofitting these?

(They seem larger than the ones they used to use, and *all* of CO's fleet have always had this model of winglets)

A/c appears to be older, but has the interior also refurbished.

Edited To Add: For a while there I thought I was on an AI flight - there was some new-age sitar music playing - wild!
