Alaska Airlines carry-on size & baggage allowance

Alaska Airlines lets you bring a free cabin bag up to 56×43×25 cm. It has to fit under the seat in front of you.

A larger cabin bag on Alaska Airlines costs varies by fare and goes in the overhead locker — add it when you book, as gate prices are higher.

Checked hold luggage on Alaska Airlines starts from $35 per bag, up to 23 kg.

Yes — if your bag is bigger or heavier than your allowance, Alaska Airlines can charge a gate fee, usually more than booking online. Measure with wheels and handles.
