The verdict, explained

At 17.5x14.5x8.5", the Travelpro Maxlite 5 Rolling Underseat Carry-On fits inside Frontier Airlines's 24x16x10" carry-on allowance with about 1.5" to spare on its tightest side. It should slide into the overhead bin without trouble at the gate sizer. On Frontier Airlines: Personal item free; carry-on paid — gate price is the highest. It is too large for Frontier Airlines's under-seat personal-item space, so it has to go overhead or be checked.

Manufacturer's note

Travelpro publishes 17.5 x 14.5 x 8.5 in overall, counting the wheels and handles, and 15.25 x 13 x 8 in for the case. The overall figure is half an inch over an 18 x 14 x 8 in personal-item limit on two sides, so our verdict says it is too big on paper. Travelpro designs it to fit under most airline seats and says it is carry-on sizer tested; the overage is the wheel housing and handles rather than the soft case. On strict budget airlines that measure personal items, treat it as a gamble.

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.
