Delta’s latest A220 delivery and program progress

The most recent A220 delivery to Delta Air Lines caught our eye.  The typical period between first flight and delivery runs close to a month, on average.  But N333DU was special.  It took eight days from first flight to delivery,  which is as far as we can tell, the best the A220 program has seen.

Because of this data point, we have an interesting item upon which to base a program review.  Airbus wants to get to rate 14, but its a long way off from that.  The present rate is closer to six.  One obvious way to increase rate is to deliver faster.
