Alaska Airlines baggage fees, size limits & special items (2026)

What is Alaska Airlines's checked bag weight and size limit?

Every bag on Alaska Airlines must weigh 50 lbs / 23 kg or less and measure no more than 62 linear inches (length + width + height) to avoid surcharges. Both limits apply independently — a light bag that is too large still triggers the oversize fee.

Fees shown are for online pre-payment where applicable. Paying at the airport counter or gate typically runs higher.

What does Alaska Airlines charge for oversize or overweight bags?

Overweight fees

Oversize fees

Both fees stack — a bag that is simultaneously overweight and oversize is charged both surcharges on the same bag in the same direction.

Does Alaska Airlines charge extra for sports equipment?

Strollers and car seats are always free to check on all airlines. Gate-check your stroller at the jetway — it is returned at the aircraft door on arrival.

Can I bring a stroller or car seat on Alaska Airlines for free?

• Strollers: free (gate-check)
• Car seats: free
• Military: 5 free checked bags (active duty)

Wheelchairs and all other mobility aids always travel free on every US carrier under DOT regulations — no fees, no size limits, no exceptions, no advance arrangements required.

How do bag fees affect my Leave-By Time?

Checking a bag adds 20–30 minutes to your airport buffer compared to carry-on only. You need time to join the bag-drop queue, hand off the bag, and collect your receipt before you can head to the TSA checkpoint. That window sits before security — not inside it — so it shifts your Leave-By Time at home earlier, not just your airport arrival.

Use the Leave-By Time calculator — enter your flight, mark that you are checking a bag, and the calculator adds the bag-drop counter step so you leave home with exact numbers instead of a rough guess.

These co-branded credit cards waive Alaska Airlines's checked bag fees for the cardholder — and sometimes companions — when the card is used to purchase the ticket:
