I'm planning a work trip for the first week of October, and I noticed an unusual flight available from DL. It is flight DL3286, SLC-CVG on 30Sept. It leaves SLC at 20:00, arriving to CVG at 01:27, operated by Pinnacle with a CR9. This appears to be a one-time-only operation. From what I can tell, DL has a very regular 2x daily service on the route for several weeks in each direction with a mix of 319/320/738 equipment. I'm assuming that this is perhaps an aircraft repositioning flight on which they have decided to sell seats. I've heard of such things, but I can't remember seeing one before (at least none that I recognized). How common is it?
Edit: I just looked again, and I see an extra flight in the opposite direction (CVG-SLC) operating early the next morning with a 738. So it looks like the 2 planes are swapping bases.
