Carry-On Baggage

The following baggage rules apply only when traveling on flights operated by Alaska Airlines and Horizon Air. If your itinerary includes travel on another airline, please check the other airline's Web site for their specific baggage rules.

You're allowed one carry-on bag, which can measure up to 10" H x 17" W x 24" L (25 x 43 x 61 cm) including wheels and handles, plus one personal item, such as a purse, briefcase or laptop computer. At least one of the items should be stowed under the seat in front of you.

Items exceeding the free carry-on allowance (see exceptions below) will be charged $25 per piece and tagged for delivery to baggage claim at the customer’s destination.

Important: Keys, medication, and travel documents should always be packed in your carry-on baggage.

Additional Carry-On Information

Carry-on baggage exceptions

The following items may count as your "one" carry-on bag and may exceed the carry-on dimensions as long as they can be safely accommodated in a proper stowage compartment in the cabin of the aircraft.
  • Art/Advertising portfolios
  • Paintings
  • Delicate scientific equipment
  • Fishing poles
  • Human organs
  • Garment bags
All items brought onboard count toward your carry-on limit except the following:
  • Coats, hats, umbrellas
  • Reasonable amount of reading material
  • FAA approved child/infant restraint seats to be occupied by a child
  • Stroller
  • Pets traveling in the cabin (Refer to our Traveling with Pets page for fees, documentation requirements and other information)
  • Mobility assistive devices (e.g. wheelchairs, canes and crutches)
  • Medical supplies and small medical equipment (e.g. CPAP machine for sleep apnea). Visit Travelers with Disabilities and Medical Conditions on the TSA website for more information on allowed medical items and screening procedures.
  • Small musical instruments (e.g. violin, flute, clarinet, guitar) provided they are of a size or shape that can be safely stowed in an overhead bin or closet. Any musical instrument (e.g. oversized or odd-shaped) that cannot be properly stowed, must be checked or travel as cabin seat baggage.
  • Ashes in an Urn. Ashes must be in a sealed, leak-proof container that fits in an overhead compartment. For information about TSA screening requirements, visit the Transporting the Deceased section of the TSA website.

Horizon Air Ala Cart Service

Horizon Air offers its unique Ala Cart planeside carry-on service for their customers. Due to the smaller dimensions of overhead storage and underseat space, passengers may place larger carry-on items on a planeside cart before boarding. These items will be specially tagged and returned to the cart for retrieval at a designated area on the ramp or jetway as the passenger deplanes. Just find the red and white stop sign and your bags will be there within 5 minutes of deplaning. Fragile or high-value items should be carried into the cabin with you, and not left on the planeside cart.

The maximum dimensions for an Ala Cart bag is 10" H x 17" W x 24" L (25 x 43 x 61 cm) including wheels and handles.

Prohibited Items

Many common items used everyday in the home or workplace may seem harmless; however, when transported by air, they can be very dangerous. In flight, variations in temperature and pressure can cause items to leak, generate toxic fumes, or start a fire.

Please refer to the Permitted and Prohibited Items of the Transportation and Security Administration (TSA) website for a complete list of items which are federally restricted from being carried onboard our aircraft.

In addition to the items found on the TSA website, Alaska Airlines and Horizon Air have additional restrictions on carrying or checking the following items:

Items marked with a green "O.K. to Pack" are OK to pack as noted.

Items marked with a red "Do Not Pack" are prohibited from your carry-on and/or checked baggage.
