Here's a link to track the first A321neo delivery flight on Wednesday:

The route is XFW-BGR-ATL. Unfortunately, the registration number (N501DA) is blocked from tracking in FlightAware and is probably blocked from tracking in FlightRadar24 as well, so we'll have to get creative about how to track this plane after it's delivered.
