Interesting find here, a Airbus A330-300 from Delta flying from IND-DTW. Pretty short run for such a large acft. Any ideas?
Most likely positioning.
Looks like they came from Jacksonville.
Probably better than taking that amount of people on 2 or 3 smaller planes. And it was available.
That JAX-IND was the Colts returning home, IND-DTW the ferry leg to base.
