Delta has gone in for the A321neo in a big way.  They are taking delivery of them at a pretty steady pace.  That doesn’t mean you get them everywhere as some types get focused on regions that others don’t.  For a while, we didn’t see too many of the neo jets up this way but that seems to have changed now.  I am seeing loads of them if I am around SEA these days.  Here is a selection of shots of their jets that I have taken in recent months.
