Does Allegiant Carry On Size Include a Personal Item in 2026?

Travelers flying with Allegiant Air often have questions about carry-on baggage rules, especially when it comes to personal items. Budget airlines usually separate baggage allowances from the base ticket price, which means understanding the limits before arriving at the airport is important. The allegiant carry on size rule explains what type of bag can be brought onboard and whether a personal item is included.

In 2026, Allegiant continues to follow a simple baggage structure: passengers can bring one free personal item, while larger carry-on bags placed in the overhead bin require an additional fee. Knowing these details helps travelers pack correctly, avoid extra charges, and move through the boarding process smoothly.

What does Allegiant consider a personal item?

A personal item is a small bag that fits under the seat in front of you. Allegiant allows one personal item per passenger without any extra charge.

• Small backpack

• Purse or handbag

• Laptop bag

• Briefcase

These items must stay within the airline’s allowed dimensions and must fit under the seat during the flight.

Does Allegiant carry-on size include a personal item?

The carry on size allegiant guideline defines the maximum size allowed for a bag that goes in the overhead bin. If your bag exceeds the personal item dimensions, it will likely be classified as a carry-on bag and may require payment.
