A 22 x 14 x 9 in bag just fits Allegiant Air's carry-on, barely.
How we measured
- Your bag 22 in x 14 in x 9 in vs Allegiant Air carry-on max 22 in x 16 in x 10 in (largest side to largest side).
- Longest side: 22 in vs 22 in allowance -> 0 in to spare.
- Middle side: 14 in vs 16 in allowance -> 2 in to spare.
- Shortest side: 9 in vs 10 in allowance -> 1 in to spare.
- Linear total: 45 in vs 48 in limit -> within limit.
- Result: within the limit, but only 0 in clearance on the tightest side. It should pass the sizer, but a full bin could get it gate-checked.
- It is over the personal-item max 18 in x 14 in x 8 in, so it does not count as an under-seat item.

Official wording (dimensions): 'Your one Carry-on Bag (such as a roll-aboard or garment bag) must fit in the overhead bin, with maximum size of 10 in. x 16 in. x 22 in. (25cm x 40cm x 55cm).'

Official wording: 'All Allegiant passengers may bring one personal item on board for no charge... Your Personal Item (like a purse, briefcase, or a small backpack) must be stored completely underneath the seat in front of you, with maximum dimensions of 8 in. x 14 in. x 18 in. (20cm x 35cm x 45cm).' Wheels/handles inclusion confirmed by the same 'all exterior measurements include wheels, pockets, handles and decorations' statement that applies to both bag types. No published weight limit.
A full carry-on is allowed on Allegiant Air's lowest fare.
Allegiant has no separate named 'basic economy' tier - every standard fare is inherently unbundled/a-la-carte: 1 free personal item is included, and BOTH the carry-on bag and any checked bag are paid add-ons on every fare unless purchased as part of a discounted bundle (bundle contents vary by route and are purchasable only at the time of original booking; once bought, a bundle cannot be partially declined/unbundled).
