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.
