Allegiant Air Carry-On Restrictions and Rules

Before zipping up your suitcase, keep these important rules in mind:-

• One-plus-one allowance:- You can bring one personal item and one paid carry-on bag.

• Measure every side:- Handles, wheels, pockets, and decorations count toward the Allegiant Air carry-on dimensions.

• Store bags correctly:– Personal items go under the seat, while standard carry-ons go in the overhead bin.

• Follow security requirements:- Liquids, aerosols, sharp objects, and other restricted items must comply with applicable airport security rules.

How Can You Bring a Carry-On Bag for Free on Allegiant Air?

Although most passengers pay extra for an overhead carry-on, there are a few ways to avoid the additional cost.

Travel With Only a Personal Item:-

The simplest option is to pack everything into a compliant personal item. This works particularly well for short trips and helps keep your travel expenses down.

Check Your Allegiant Honors Eligibility:-

Allegiant Honors provides eligible U.S. military personnel, veterans, and qualifying family members with baggage benefits. These include one carry-on bag and one personal item within the airline’s size limits. Eligible travelers must present the required identification for verification. 

Review Bundles and Promotions:-

Some flight bundles or promotional offers may include baggage benefits. Before purchasing an upgrade, check exactly which services are included in your selected package. Don’t assume that every vacation package automatically includes a free carry-on.

In a nutshell, measure your Allegiant Air Carry On bags carefully, check the baggage price during booking, and choose a personal item that fits under the seat. For further clarification on your Allegiant baggage doubts, dial (866) 719-3910.
