Bags that fit the checked bag limit
These are full-size checked bags that stay inside the size limit with wheels and handles included. Checked size limits are generous - it's the weight limit that usually catches people - so each of these gives you close to the maximum packing space the rules allow.
How strict is Allegiant Air at the gate, really?
Allegiant Air is an aggressive enforcer: its carry-on bag is not free and gate agents actively size bags. A bag caught over the personal item allowance is charged at the gate, which is the most expensive way to pay. Measure with wheels and handles, and if you are close, expect it to be checked.
