Alaska Airlines Baggage Fees: Carry-On & Checked Bag Guide

Understanding baggage rules before your flight can help you avoid unexpected fees and make airport check-in easier. The Alaska Airlines Baggage Policy explains how many bags passengers can bring, the permitted dimensions and weights, and when additional charges may apply. Rules can vary by itinerary, fare, destination, and passenger eligibility, so checking the details before departure is always recommended.

Alaska Airlines Carry-On Baggage

Alaska Airlines generally allows each passenger to bring one carry-on bag and one personal item. The standard carry-on size is up to 22 x 14 x 9 inches, including wheels and handles. A personal item can include something such as a purse, briefcase, or laptop bag and should fit under the seat in front of you. 

Passengers should make sure their carry-on meets the size requirements before arriving at the airport. Bags that are too large or exceed the permitted allowance may need to be checked, potentially resulting in additional fees.

Alaska Airlines Checked Baggage Fees

For North American Alaska Airlines and Hawaiian Airlines flights, Alaska Airlines updated its standard checked baggage fees for tickets issued on or after April 10, 2026. The current published fees are $45 for the first checked bag, $55 for the second, and $200 for the third or additional checked bag. 

These standard charges may not apply to everyone. Certain Atmos Rewards status members, eligible Alaska Airlines credit cardholders, active-duty military personnel, and passengers traveling under specific programs may qualify for free or reduced baggage allowances. 

Checked Bag Weight and Size Limits

When preparing checked luggage, passengers should pay attention to both weight and dimensions. Standard checked baggage allowances can depend on the fare, route, and cabin. First Class passengers may receive a higher weight allowance on eligible itineraries.

Oversized or overweight luggage can result in additional charges. Alaska Airlines' April 2026 fee update lists a $200 oversized-bag fee, while certain oversized-and-overweight combinations can cost $300 or $400, depending on the bag's weight. 

Because fees can differ by itinerary, travelers should verify their specific reservation before packing.

Who May Get Free Checked Bags?

Some travelers can receive baggage benefits under the Alaska Airlines Baggage Policy. Eligible Atmos Rewards members, qualifying Alaska Airlines credit cardholders, and active-duty U.S. military personnel may receive free checked baggage benefits. Alaska Airlines also lists specific benefits for programs such as Club 49 and Huaka‘i.

For example, eligible Alaska Airlines Visa Signature cardholders can receive a free first checked bag for themselves and up to six guests on the same reservation when the qualifying flight is paid for with the card. 

Tips to Reduce Baggage Costs

Planning ahead can help you manage your baggage expenses. First, measure and weigh your luggage before leaving home. Using a carry-on within the permitted dimensions can help you avoid a checked-bag charge.

You should also review your reservation to determine whether you already qualify for a baggage waiver. Alaska Airlines allows passengers to pay applicable baggage fees during the check-in process, including through its mobile app. 

Keep in mind that seasonal baggage restrictions may apply on certain routes and during busy travel periods.

Final Thoughts

The Alaska Airlines Baggage Policy provides important guidelines for carry-on and checked luggage. With a standard carry-on allowance of 22 x 14 x 9 inches and current standard checked-bag fees starting at $45 for the first bag on applicable North American itineraries, understanding the rules can help you plan your trip more efficiently.
