Alaska Airlines Carry On Size (2026)

Alaska Airlines carry-on size is 22×14×9 in, plus how the free personal item pairs with it and notes on the Saver fare. Official sources linked.

Quick answer

Alaska’s published carry-on size is 22 × 14 × 9 in (handles and wheels included) or 45 linear inches or less. 1 carry-on and 1 personal item are free on every fare, including Saver, Main, and First. Alaska does not publish a carry-on weight limit or official carry-on cm. The personal item must fit under the seat; no length, width and height are published.

Free and paid

Free with every ticket: one carry-on within the size limit (22 × 14 × 9 in, or 45 linear in or less) plus one under-seat personal item, including on Saver.

Unlike United Basic Economy: Alaska Saver includes the free overhead carry-on (same cabin allowance as Main). The tradeoff is boarding Group F (bins may fill), not a carry-on fee.

Paid: checked bags only. Domestic and North America standard for tickets bought on or after April 10, 2026: 1st bag $45, 2nd bag $55 each way (the full fee list, overweight and oversize fees, and Atmos, Visa, military and Club 49 waivers are on Alaska baggage fees). Other cabin fees are covered on our baggage fees page.

Gotchas

  • Airport bag sizers enforce 22 × 14 × 9; on a full flight agents may gate-check bags that fit the rule but don’t fit remaining bins.
  • Saver boards Group F (last), so overhead may fill; your carry-on is still free, but it may be gate-checked. Keep essentials in the under-seat personal item.
  • Personal item: no published L×W×H. See Alaska personal item.
  • Carry-on weight: none stated.
  • Official cm are not published. Blogs citing exact cm are usually converting; treat those as unofficial unless Alaska later publishes cm.
  • Codeshares: check your confirmation to see which airline’s baggage policy applies.

Avoid fees

  1. Stay at or under 22 × 14 × 9 in, or 45 linear in; measure including wheels and handles before you travel.
  2. Pack a true under-seat personal item as backup if bins are full or you board late on Saver (Group F).
  3. For checked bags, see the fees page: the table for tickets bought on or after April 10, 2026 shows no prepaid discount.
  4. Alaska Saver’s free carry-on is not the same as United Basic Economy (personal-item only on most domestic routes).

Bags that fit

These are loose suggestions only: measure your packed bag before travel. Look for bags marketed as airline carry-on or “22×14×9” compliant that stay at or under Alaska’s published 22 × 14 × 9 in, or 45 linear in, including wheels and handles. Under-seat companions should fit under the seat when packed (Alaska publishes no personal-item L×W×H).

When shopping, filter for bags of 22×14×9 in or smaller, or 45 linear inches or less, and measure them yourself.

FAQ

What is the Alaska Airlines carry-on size?

22 × 14 × 9 inches or 45 linear inches, including wheels and handles. Alaska does not publish official carry-on cm on the carry-on page. There is no published carry-on weight. You must be able to lift it into the overhead bin.

Does Alaska charge for carry-on bags?

No. One carry-on that meets the size limit plus one personal item is free on all fares, including Saver.

Does Alaska Saver include a free carry-on?

Yes. Saver includes the same free carry-on and personal item as Main. Saver guests board in Group F, so overhead may be limited even though the bag is free.

What if my bag doesn’t fit the Alaska size check?

Expect to check it (fees may apply for checked pieces; see baggage fees for $45 and $55 on tickets bought on or after April 10, 2026).

What is Alaska’s personal item size?

Must fit under the seat. Alaska does not publish an exact length, width and height, only examples (purse, briefcase, laptop bag). Full detail: Alaska personal item.

Is Alaska carry-on the same as Delta, United, or JetBlue?

Alaska uses the same common 22×14×9 size as Delta, United and JetBlue (JetBlue also publishes official cm). Alaska’s advantage over United Basic Economy: Saver still includes free overhead. Alaska’s official carry-on page gives inches and linear inches only; cm are not published.
