The verdict, explained

At 21.75x14.5x11", the Patagonia Black Hole Wheeled Duffel 40L exceeds Allegiant Air's 22x14x9" carry-on sizer — it is 0.5" too big on its second-longest side, 2" too big on its shortest 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.

💡 At the gate

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.
