Hawaiian Airlines Carry-On Rules & Bag Size 2026

Hawaiian Airlines currently allows one carry-on and one personal item. The carry-on must fit 22×14×9 inches, including wheels and handles, and must not exceed 45 linear inches. The metric conversion is 55.88×35.56×22.86 cm, with 114.3 cm total. The current page applies this allowance on all aircraft.

The published allowance

You must be able to lift and stow your own bag. An unknown numeric weight is not a promise that any weight will be accepted. Do not apply the former CarrySizer 45×35×25 cm box, an invented 17 cm depth or an extra First Class main bag. Standard carry-on is included for Saver/Main/First under the current checked-baggage table.

Measuring and planning a connection

Measure the packed exterior, including wheels and handles. A bag marketed as a US carry-on can still exceed a stated side; compare actual measurements in the bag checker. The personal-item checker cannot confirm a box the source does not publish. Choose a small item that can be safely stowed under the seat and confirm uncertain dimensions with the carrier.

A compliant bag does not guarantee overhead space. Follow crew instructions if a bag needs checking and keep essential documents and any items prohibited in checked baggage with you. Another operating carrier can set different rules on a connection; use the route checker and verify each segment.

Hawaiian brand and AS flight code

The carrier's 22 April 2026 passenger-system announcement says all flights now use AS codes while the Hawaiian brand continues. Choose Hawaiian by name when checking its branded service; a shared flight prefix does not establish every cabin or fare detail. This change does not mean Hawaiian has ceased operating.

Travelling with children

Under the current shared Alaska/Hawaiian family policy, a lap infant does not have a separate carry-on allowance: a diaper bag counts toward the accompanying adult's allowance. Domestic US lap-infant travel is free; international pricing depends on itinerary.

A child car seat and stroller may be checked free at the counter or gate, with separate conditions for stroller wagons. An FAA-approved restraint occupied by the child can be used in the cabin subject to seating and fit rules. Do not infer that every purchased-seat car seat is accepted, or that checked equipment always returns at the aircraft door.

Fees and security

Checked-bag prices vary by route, ticket date and card/status/resident-program eligibility. Do not assume a free interisland checked bag for every passenger or a universal extra-cabin fee. Confirm the actual booking and the departure/transfer security rules for liquids and restricted items.
