The verdict, explained

At 21.7x14.8x10", the Amazon Basics 21-Inch Hardside Carry-On fits inside Spirit Airlines's 22x18x10" carry-on allowance, right at the limit. It should slide into the overhead bin without trouble at the gate sizer. On Spirit Airlines: Personal item free; carry-on is PAID — cheapest if added online. It is too large for Spirit Airlines's under-seat personal-item space, so it has to go overhead or be checked.

Airlines measure at the widest external point — wheels, handles, and bulging pockets all count. Pull soft-bag compression straps fully tight before you size it.
