Alaska Carry On Dimensions – Everything You Need to Know Before You Fly

When traveling with Alaska Airlines, one of the most important things passengers should be aware of is the carry-on baggage policy. Understanding the Alaska carry on dimensions can save you from last-minute stress, unexpected fees, or the hassle of checking your bag at the gate. At FaresMatch, we make it easier for you by breaking down Alaska Airlines’ carry-on rules, allowances, and tips to ensure your trip goes smoothly.

Alaska Airlines Carry-On Size Policy

Alaska Airlines allows every passenger to bring one carry-on bag and one personal item free of charge. To avoid issues at boarding, your carry-on bag must meet the airline’s size restrictions.

The official Alaska carry-on dimensions are:

• 22 x 14 x 9 inches (56 x 36 x 23 cm), including wheels and handles.

If your bag exceeds this limit, you may be asked to check it in. The good news is that Alaska has one of the more generous carry-on size policies compared to some other U.S. airlines.

Personal Item Allowance

In addition to your standard carry-on bag, Alaska Airlines also permits one personal item that should fit under the seat in front of you. Typical personal items include:

• Backpack

• Purse or handbag

• Laptop bag

• Briefcase

• Small tote

Personal item size guideline: While Alaska does not publish strict personal item dimensions, it must be smaller than your carry-on and easily fit under the seat.

Carry-On Weight Limit

Unlike some international carriers, Alaska Airlines does not have a specific weight limit for carry-on bags. However, passengers must be able to lift the bag into the overhead bin without assistance. This flexibility makes Alaska a popular choice for travelers carrying heavier items like electronics or business materials.

What Counts as Free Carry-On Items?

Alaska Airlines is traveler-friendly when it comes to additional small items. Along with your carry-on and personal item, you can bring a few extras onboard at no charge, including:

• A jacket or coat

• Umbrella

• Duty-free shopping bags

• Assistive devices (crutches, walkers, canes)

• Diaper bags for infants

These do not count toward your main carry-on allowance.

Tips to Make Sure Your Bag Meets Alaska Carry On Dimensions

1. Measure Before You Pack: Use a measuring tape to confirm your suitcase fits the 22 x 14 x 9-inch rule.

2. Consider Soft-Sided Bags: They are more flexible and easier to fit in overhead bins.

3. Use Expandable Zippers Wisely: Expanded luggage may exceed the limit, so zip it down before boarding.

4. Pack Smart: Keep essentials and valuables in your carry-on. If the bag is gate-checked, you’ll still have your must-have items with you.

5. Check Crowded Flights: On full flights, even compliant carry-ons may be gate-checked. Be prepared by packing valuables in your personal item.

Overhead Bin Space – First Come, First Served

Even if your bag meets the required dimensions, overhead bin space can run out, especially on popular routes or smaller aircraft. Alaska Airlines boards passengers in groups, and travelers seated in later groups may have fewer storage options. To secure space:

• Check in early.

• Board promptly when your group is called.

• Place your bag wheels-first in the bin to maximize space.

Carry-On Rules for Different Fare Types

Alaska Airlines offers different fare classes, but unlike some budget carriers, every passenger, regardless of fare type, is allowed a carry-on bag and a personal item for free.

This applies to:

• Main Cabin

• Premium Class

• First Class

• Saver Fares (basic economy)

Even Saver Fare passengers can bring a full-size carry-on, which makes Alaska more customer-friendly compared to airlines that restrict lower-tier fares.

Traveling with Kids and Families

Alaska Airlines is accommodating for families. Parents traveling with infants or young children can bring diaper bags, child safety seats, and strollers free of charge. A diaper bag does not count as the personal item, making it easier for families to manage carry-on items.

International Travel and Codeshare Flights

If your trip involves a codeshare with another airline, make sure to check that carrier’s carry-on policies. For example, if you’re flying Alaska Airlines domestically but connecting to an international partner airline, the carry-on dimensions may differ. Always review your entire itinerary to avoid surprises.

Prohibited Items in Carry-On Bags

Regardless of size compliance, certain items are not allowed in your carry-on. TSA rules apply to all airlines, including Alaska. Common prohibited items include:

• Liquids over 3.4 ounces (except medications, baby formula, or breast milk)

• Sharp objects like knives or scissors (blades longer than 4 inches)

• Firearms and ammunition (unless properly declared in checked baggage)

• Flammable items (lighter fluid, fireworks, etc.)

Tip: Always check TSA guidelines before packing.

Benefits of Following Alaska Carry On Dimensions

Sticking to Alaska’s carry-on size rules offers multiple benefits:

• Saves money by avoiding checked bag fees.

• Saves time since you can skip baggage claim.

• Keeps essentials safe with you at all times.

• Offers flexibility if you have tight connections.
