Travelers from the Twin Cities were furious upon arriving at Las Vegas to find their luggage hadn't made the journey.
The incident affected Flight 117 from Minneapolis-St. Paul International to Las Vegas McCarran on Thursday night.
None of the 168 passengers' hold luggage made the journey, and had to be flown out to them the next day.
KSTP reports that all passengers received their luggage on Friday, either having to go to the airport to pick it up or by having it delivered to them where they're staying in Vegas.
The company told the TV station it realized its error pretty quickly, and has been refunding bag fees and offering a $50 voucher to impacted customers.
Nonetheless, it is another black mark against Sun Country at a time its reputation has really taken a hit.
