Reading into the story, this aircraft is here in the states, for the purpose of demo and promotion.

It’s unlikely they are pitching the 220 to DL or JB. Can’t imagine SWA or Alaska is interested either. It would be hard to believe that Airbus isn’t attempting to sell their latest and greatest to one of their best customers. Haven’t done the numbers yet but the combined NK/F9 fleet may become one of the world’s largest narrow bus operators?
