For some reason I was thinking about the comparison between the neo and classic versions of the A320 family and it got me wondering whether I had any shots that would provide a good direct comparison between the old and new versions.  The answer I came up with was shots of American Airlines’ A321s departing LAX.  They provided the combination of reliable lighting and similar angles on the climb out.  I was able to put the two together in one shot.  Externally, the differences are there to be seen but, if you are not knowing what to look for, you probably wouldn’t tell them apart.  Given the significant performance increase the neo brings, it would be easy to miss.
