The verdict, explained

At 23.5x14.5x9", the Travelpro Platinum Elite 21" Expandable Carry-On Spinner fits inside Sun Country Airlines's 24x16x11" carry-on allowance with about 0.5" to spare on its tightest side. It should slide into the overhead bin without trouble at the gate sizer. On Sun Country Airlines: Carry-on and checked bags are paid add-ons. It is too large for Sun Country Airlines's under-seat personal-item space, so it has to go overhead or be checked.

Manufacturer's note

Travelpro publishes two sizes for this bag: 23.5 x 14.5 x 9 in overall, counting the wheels and the top and side carry handles, and 21 x 14 x 9 in for the case itself. Our verdict uses the overall figure, which is over a 22 x 14 x 9 in sizer on paper. Travelpro says the bag is sizer-bin tested to fit the overhead bins of most major US airlines, because the soft carry handles fold flat; only the expanded bag may not meet airline limits. Keep it zipped unexpanded at the gate.
