Alaska carry-on size

Alaska’s published carry-on size is 22 × 14 × 9 in (handles and wheels included) or ≤ 45 linear inches. 1 carry-on + 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 L×W×H published.

Field	Alaska published value
Max dimensions (in)	22 × 14 × 9 in (handles & wheels included; airport bag sizers)
Max dimensions (cm)	Not published — official page is inches / linear only (do not treat blog conversions as official)
Linear	≤ 45 linear in (L+W+H; official alternative to 22×14×9)
Weight	None published — must lift into the overhead
Wheels / handles	Included in 22×14×9
Fare inclusion	Free — all fares incl. Saver / Main / First (Saver ≠ ultra-basic)
Personal item (cross-ref)	Under the seat; no published L×W×H — examples only → personal item
Saver boarding	Group F (last) — bin space first-come; carry-on still free

Free with every ticket: one size-compliant carry-on (22 × 14 × 9 in / ≤ 45 linear in) 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 / North America standard for tickets on/after Apr 10, 2026: 1st $45, 2nd $55 each way (full ladder, overweight/oversize, Atmos / Visa / military / Club 49 waivers → Alaska baggage fees). Don’t invent other cabin fees here.

• 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) — 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 — don’t invent dims or copy United / JetBlue / Frontier numbers as Alaska’s. See Alaska personal item.
• Carry-on weight: none stated — don’t invent a cabin lb/kg limit.
• Official cm not published — blogs citing exact cm are usually converting; treat those as unofficial unless Alaska later publishes cm.
• Codeshares: which airline’s baggage policy applies — check your confirmation.

1. Stay ≤ 22 × 14 × 9 in / ≤ 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 Apr 10, 2026+ table shows no prepaid discount.
4. Don’t confuse Alaska Saver’s free carry-on with United Basic Economy (personal-item only on most domestic routes).

Soft picks only — measure your packed bag before travel. Look for bags marketed as airline carry-on / “22×14×9” compliant that stay at or under Alaska’s published 22 × 14 × 9 in / ≤ 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).

AmazonCard — Alaska-size carry-on (~22×14×9 / ≤45 linear)
Softside or hardside spinner marketed as carry-on compliant for major U.S. airlines. Confirm the product’s listed exterior dimensions (wheels/handles included) are ≤ 22 × 14 × 9 in or ≤ 45 linear in before you buy, then re-measure when packed so it clears Alaska’s bag sizer.

AmazonCard — Under-seat personal item
Slim backpack or tote aimed at under-seat fit. Useful as your reliable cabin bag on Saver (Group F) when overhead fills late. Prefer non-expanding designs; Alaska does not publish official personal-item inches — measure your packed bag against the under-seat space.

What is the Alaska Airlines carry-on size limit?

22 × 14 × 9 inches including handles and wheels, or ≤ 45 linear inches combined. The official site does not publish carry-on cm. No published carry-on weight limit.

Does Alaska charge for carry-on bags?

No — one size-compliant carry-on plus one personal item is free on all fares, including Saver.

Does Saver include a carry-on on Alaska?

Yes — same free carry-on + personal item as Main. Saver boards Group F (last), so bins may fill and bags may be gate-checked free. Unlike United Basic Economy, Saver is not personal-item-only.

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 / $55 on tickets on/after Apr 10, 2026).

What is Alaska’s personal item size?

Must fit under the seat — Alaska does not publish exact L×W×H; examples only (purse, briefcase, laptop bag). Full detail: Alaska personal item.

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

Same common 22×14×9 family as Delta / United / JetBlue (JetBlue also publishes official cm). Alaska’s edge vs United BE: Saver still includes free overhead. Alaska’s official carry-on page is inches + linear only — cm not published.
