The verdict, explained

At 22x14.25x9.25", the Travelers Choice Indestructible Hardshell exceeds Allegiant Air's 22x14x9" carry-on sizer — it is 0.2" too big on its second-longest side, 0.2" too big on its shortest side. 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.

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.
