The verdict, explained

At 21.7x14.8x10", the Amazon Basics Expandable Hardside Carry-On fits inside Sun Country Airlines's 24x16x11" carry-on allowance with about 1" 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.
