How We Check This Policy: At BagPolicyInfo, our editorial team pulls baggage details directly from Alaska Airlines’ official travel guides, examining carry-on allowances and checked bag structures separately so travelers can prepare for sizing and fee differences across domestic and international itineraries.
Official Bag Policy Overview
Alaska Airlines maintains a passenger-friendly carry-on policy: each traveler is permitted one rollaboard or duffle measuring up to 22″ × 14″ × 9″ and one personal item, completely free of charge under the alaska airlines bag policy. There is no set weight ceiling on carry-on luggage, as long as travelers can store it overhead without flight attendant assistance. Checked baggage requires payment on standard Main and Saver tickets: the first bag is $45 and the second bag is $55, with luggage capped at 62 linear inches and 50 lbs.
What Makes This Policy Different?
Unlike low-cost carriers that charge for overhead carry-on space or enforce strict 15–22 lb carry-on limits, Alaska Airlines provides free carry-on allowance without a fixed weight ceiling. On checked baggage, Alaska aligns with major domestic carriers by charging $45 for the first piece and $55 for the second on base economy fares. Elite status holders (MVP, MVP Gold) and Alaska Airlines Visa cardholders enjoy complimentary checked baggage allowances on qualifying flights.

Personal Items
Passengers may bring one personal item — such as a purse, briefcase, small backpack, or laptop sleeve — that fits under the seat in front of you at no additional fee.
Checked Baggage
Standard checked bags are capped at 62 linear inches (length + width + height) and 50 lbs. On Main and Saver fares, the first checked bag is $45 and the second checked bag is $55.
Overweight and Oversized Baggage

Prohibited Bags and Items Under Alaska Airlines Rules
Federal aviation regulations and Alaska Airlines policies strictly prohibit the following items in carry-on and checked luggage:
- Oversized Carry-Ons: Rollaboards exceeding 22″ × 14″ × 9″ must be checked at the gate or ticket desk
- Bags Over 100 lbs: Personal baggage over 100 lbs (45 kg) is strictly prohibited as checked baggage
- Excessively Large Luggage: Bags exceeding 115 linear inches total dimensions
- Smart Bags with Non-Removable Batteries: Smart luggage containing integrated lithium-ion batteries that cannot be detached
- Hazardous Materials: Flammables, camping fuel, fireworks, and defense sprays over TSA limits
- Loose Liquids Over 3.4 oz: Liquids in carry-ons exceeding 3.4 oz (100 ml) must travel in checked baggage under TSA 3-1-1 rules
- Sharp Objects: Knives, box cutters, and tools exceeding 7 inches are banned from cabin baggage
How Security Screening and Gate Checks Work
At airport security checkpoints, TSA agents verify your boarding pass and screen carry-on items through X-ray equipment. At Alaska Airlines departure gates, gate agents visually evaluate carry-ons and may require passengers to insert questionable bags into metal sizing templates. If an overhead flight is full, Alaska gate staff may offer complimentary gate-checking for compliant carry-ons to your final destination. Checked baggage is automatically weighed and measured at ticket counter scales, where any overweight surcharges are assessed.
Packing Strategy for Faster Travel
- Measure wheels and handles: Confirm your rollaboard does not exceed 22″ × 14″ × 9″ from wheel base to top handle under the alaska airlines bag policy.
- Keep essentials in your personal item: Place medications, chargers, identification, and electronics in your under-seat bag in case of gate checks.
- Weigh checked bags at home: Use a digital luggage scale before heading to the airport to avoid the $100 overweight surcharge for bags over 50 lbs.
- Pre-pay baggage fees online: Check in via the Alaska Airlines mobile app 24 hours prior to departure to pay baggage fees quickly.
- Pack TSA liquids together: Place travel-sized liquids in a transparent 1-quart zip-top bag near the top of your personal item.
- Utilize airline credit card perks: If you hold an eligible Alaska Airlines credit card, ensure your Mileage Plan number is attached to receive free first checked bags.
Travel Check Anxiety Tips
Navigating airport baggage rules doesn’t have to be stressful. Packing your carry-on slightly below the 22″ × 14″ × 9″ maximum ensures it easily slides into the overhead bin even on smaller regional E175 aircraft. If you are checking luggage, keeping weight around 45–47 lbs provides a comfortable safety buffer against home scale discrepancies.
Day-of Travel Tips From BagPolicyInfo
- Weigh before leaving home: Keeping your bag under 50 lbs avoids the steep $100 overweight fee.
- Label all luggage: Affix durable luggage tags with your phone number and email to both carry-on and checked bags.
- Pack smart for regional jets: On Horizon Air or SkyWest regional flights operating for Alaska, larger carry-ons may be gate-checked on the jet bridge (Ala-Cart).
- Remove lithium batteries: Never place power banks or spare lithium batteries in checked baggage; they must stay in your carry-on.
Category-Specific Packing Tips
Business travelers: Pair a tailored under-seat laptop briefcase with a compact 20-inch carry-on to skip ticket counter and baggage claim lines entirely.
Families with infants: Alaska Airlines checks strollers and car seats for free at either the ticket counter or gate; diaper bags fly as standard carry-on or personal items.
Sports & outdoor enthusiasts: Ski gear, golf bags, and fishing equipment count as a standard checked bag if within 50 lbs, though regular checked fees apply.
