Sun Country @ RDU

I was out at RDU tonight and saw this arrive:
I also see this:

What would that be? Sun Country doesn’t have service at RDU. I guess some sort of charter(??). Anybody have any insight?

The flight number would indicate a charter - Suncountry uses 8xxx series flight numbers for charters.

Not really sure why it was coming to RDU from Kinston, but I’d say it was a charter. Bringing someone to Raleigh to play the Canes maybe, then going to Columbus to pick up the Blue Jackets and take them to another one of their games.
