Flying with Allegiant Air is a fantastic way to save on airfare, but hidden baggage fees can quickly ruin a budget trip. To keep your travel completely free, you need to know the rules.
Quick Answer: What Is the Allegiant Personal Item Size?
Allegiant says every passenger may bring one personal item free, and the maximum personal item dimensions are 8 x 14 x 18 inches. Carry-on bags must not exceed 10 x 16 x 22 inches, and checked bags can weigh up to 50 lbs, with a maximum size of 80 linear inches. If your bag is too large, it may be treated as a paid carry-on at the gate, where baggage fees are usually higher. A paid Allegiant carry-on bag must not exceed 10 x 16 x 22 inches, including wheels, handles, pockets, and decorations.
Allegiant Personal Item Size
Here are the current personal item limits for Allegiant Air.
| Bag Type | Correct Allegiant Size | Where It Goes | Fee |
|---|---|---|---|
| Personal Item | 8 x 14 x 18 inches | Under the seat | Free |
| Carry-On Bag | 10 x 16 x 22 inches | Overhead bin | Paid |

FlyingTip: Use a soft-sided backpack instead of a hard suitcase. Soft bags are easier to compress and are more likely to fit inside Allegiant’s sizing bin.
What Counts as a Personal Item?
A personal item is a small bag that fits under the seat.
Examples include:
- Small backpack
- Laptop bag
- Purse
- Tote bag
- Camera bag
- Small diaper bag
These items are included with every Allegiant ticket at no additional cost.
What Doesn’t Count as a Personal Item?
The following items are usually too large:
- Standard carry-on suitcase
- Large hiking backpack
- Duffel bag larger than the size limit
- Rolling cabin luggage
If your bag doesn’t fit inside the personal item sizer, you’ll likely need to pay for a carry-on bag.
| Bag Type | Allowed as Personal Item? |
| Small Backpack | ✅ Yes |
| Purse | ✅ Yes |
| Laptop Bag | ✅ Yes |
| Tote Bag | ✅ Yes |
| Small Duffel | Sometimes |
| Carry-On Suitcase | ❌ No |
| Large Backpack | ❌ No |
Does Allegiant Measure Personal Items?
Yes. Gate agents may ask passengers to place their bag inside the airline’s sizing bin before boarding.
If the bag fits without forcing it, you’re usually allowed to bring it onboard as your free personal item. If it doesn’t fit, you’ll likely need to pay the applicable carry-on baggage fee before boarding.
FlyingTip: Avoid overpacking your backpack. Even if the dimensions are correct, an overfilled bag may not fit inside the sizing bin.
Personal Item vs Carry-On Bag
Many travelers confuse these two baggage options.
| Feature | Personal Item | Carry-On Bag |
| Included Free | ✅ Yes | ❌ No |
| Stored Under Seat | ✅ Yes | ❌ No |
| Stored Overhead Bin | ❌ No | ✅ Yes |
| Additional Fee | No | Yes |
| Best For | Short Trips | Longer Trips |
If you’re travelling for just a weekend, a properly packed personal item may be all you need in Allegiant airlines.
Can I Bring Both a Personal Item and a Carry-On?
Yes. Passengers who purchase a carry-on bag may bring:
- One personal item (free)
- One paid carry-on bag
This gives you additional packing space while still keeping essential items within easy reach during the flight. Chec the best time to book flights and for special discounts call us at our phone.
How to Avoid Paying Extra Baggage Fees
The easiest way to save money is to plan ahead.
- Measure your bag before leaving home.
- Pack light for short trips.
- Buy your carry-on during booking instead of at the airport.
- Use packing cubes to maximise space.
- Keep electronics and travel documents inside your personal item.
FlyingTip: Airport baggage fees are almost always higher than online baggage prices. If you know you’ll need extra luggage, purchase it before your travel day.

Final Thoughts
Understanding the Allegiant personal item size before your trip can help you avoid unnecessary baggage fees and make boarding much easier.
For most travelers, a small backpack, laptop bag, or tote easily meets the airline’s size requirements. If you need more space, purchasing a carry-on online before your flight is usually much cheaper than paying at the gate.
