Travelpro Maxlite 5 Rolling Underseat Carry-On on Allegiant Air
Bag 17.5×14.5×8.5" vs sizer 22×14×9"
No — it's oversized.
The verdict, explained
At 17.5x14.5x8.5", the Travelpro Maxlite 5 Rolling Underseat Carry-On exceeds Allegiant Air's 22x14x9" carry-on sizer — it is 0.5" too big on its second-longest side. Even with the straps pulled tight, the overage is too large to count on squeezing it in. Expect it to be turned away at the gate and gate-checked. On Allegiant Air: Personal item free; carry-on is a paid add-on. It is too large for Allegiant Air'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.
