- Middle side: 14 in vs 16 in allowance -> 2 in to spare.
- Shortest side: 9 in vs 10 in allowance -> 1 in to spare.

- 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.

Frontier Airlines' lowest fare does NOT include a full carry-on.
Frontier's cheapest fare is 'Basic.' It includes ONLY 1 free personal item - a full carry-on bag is NOT included and must be purchased separately at Frontier's dynamic bag pricing, same as a checked bag. Carry-on becomes free only starting at the 'Economy' bundle/fare tier and above, or with Elite Silver+ status. This is the classic ultra-budget-carrier gotcha: on the base fare, only the personal item is free, and carry-on IS a paid add-on.
