Alaska Airlines — official cabin limits
| Allowance | Max dimensions (inches — the airline's own figure) Second line: our conversion | Max weight |
|---|---|---|
| Free personal item | No dimensions published | Not stated |
| Carry-on | 22 × 14 × 9 in ≈ 55.8 × 35.5 × 22.8 cm | Not stated |
How to read these numbers — Alaska Airlines publishes these limits in inches — the unit its airport sizers are built to. The centimetre figures are our own conversion, always rounded down. Airlines that print both units often print two figures that don't agree with each other — sometimes looser, sometimes stricter. When they disagree we go by the airline's own unit and round the other one down. Packing to our number keeps you inside the real limit.
What to expect
Alaska Airlines allows one carry-on of 22 × 14 × 9 in (55.8 × 35.5 × 22.8 cm), with a combined cap of 45 linear inches, plus one personal item, free on every fare. The carry-on is measured with wheels and handles, and there is no weight limit beyond being able to lift it into the overhead bin yourself. Alaska does not publish a size for the personal item; it only has to fit under the seat in front of you.
Soft bag vs hard case
Alaska is generous for a US carrier: both bags are free on every fare and there is no weight limit, so the size is the only real test. The carry-on must clear 22 × 14 × 9 in and 45 linear inches with wheels and handles included, and airport sizers are built to those dimensions. A soft, expandable bag can creep over 45 linear inches once packed, so measure it full.
Boarding tips
- The carry-on and the personal item are both free on every fare; there is no Alaska fare that charges for the standard carry-on.
- The carry-on must fit 22 × 14 × 9 in and stay within 45 linear inches (length plus width plus height), wheels and handles included.
- There is no weight limit; the only rule is that you can lift the bag into the overhead bin yourself.
- Alaska does not publish a personal item size; it just has to fit under the seat in front of you.
- On full flights Alaska may gate-check your carry-on free of charge, so keep valuables and medication in your personal item.
