Alaska Airlines Carry-On Size

Alaska Airlines allows a carry-on up to 22 x 14 x 9 inches (56 x 36 x 23 cm), measured with wheels and handles included, plus one personal item that fits under the seat. The carry-on is included on every Alaska fare, including the discounted Saver fares, which is worth saying plainly because it is not true on every airline. These numbers were accurate as of mid-2026; allowances change, so always verify with Alaska before flying.

Alaska's carry-on allowance, exactly

Alaska's carry-on limit is 22 inches long, 14 inches wide, and 9 inches deep, and the measurement is the total space the bag occupies: wheels, feet, side handles, and the housing of the telescoping handle all count. This is the same standard used by Delta, American, United, and JetBlue, so a bag that clears one of them clears Alaska. The trap, as always, is marketing labels; a "22 inch" bag measured by its body can stand 23 inches or more once the wheels are counted, and 23 inches is what the sizer sees. Measure your bag standing upright from the floor to its highest point with the handle retracted.

Alaska shrank its carry-on allowance to this standard some years ago after publishing a larger limit, which is a useful reminder that airline numbers move. The airline's site is the final word before any trip.

The personal item

Alongside the carry-on, every passenger brings one personal item: a purse, laptop bag, briefcase, or small backpack that fits under the seat in front of you. Alaska treats "fits under the seat" as the operative test rather than policing an exact dimension, so a soft bag that compresses is safer than a rigid case at the edge of underseat space. The usual free extras do not count against either allowance: a coat, an umbrella, a diaper bag when traveling with a child, food purchased in the terminal, and approved assistive devices. For help deciding what belongs in which bag, see our guide to the personal item vs the carry-on.

Saver fares still get a full carry-on

Alaska's Saver fares are the restricted cheap tier: you board last, seats are assigned late, and changes are limited. What Saver does not restrict is the cabin baggage allowance. A full-size carry-on plus a personal item is included on every fare Alaska sells. Compare that with United, where the basic domestic fare has excluded the full carry-on, or with Spirit and Frontier, where the carry-on is a paid product on standard fares, and Alaska's position is one of the friendlier ones in the US industry. Fare structures get revised, so confirm your fare's inclusions when you book, but as of mid-2026 the carry-on comes with the ticket.

Weight: no published limit, but you lift it yourself

Alaska publishes no carry-on weight limit for domestic flights. The working rule is that you must be able to lift the bag into the overhead bin without assistance; crew are not required to hoist it for you, and a bag you cannot lift can be gate-checked. Internationally, partner airlines on a connecting itinerary may enforce their own caps, commonly 7 to 12 kg (15 to 26 lb), and the strictest rule on the itinerary is the one to pack for. Our carry-on weight limits guide covers which carriers weigh bags and which do not.

Bin space, boarding order, and the gate-check flow

The published rule is one thing; the physics of a full flight is another. Alaska boards by group, and Saver passengers board last, which matters because overhead bins fill from the front of the boarding order. On a full flight, passengers boarding in the final groups routinely find the bins full even with perfectly compliant bags. When that happens, Alaska gate-checks remaining roller bags free of charge: the agent tags the bag at the jet bridge, it rides in the hold, and you collect it at baggage claim or, on some regional flights, at the aircraft door.

Gate-checking a compliant bag costs nothing, but it costs time at arrival and it puts the bag out of your sight. Anything you cannot afford to lose contact with, medication, laptops, and spare lithium batteries above all, belongs in the personal item, because spare batteries must never travel in a checked or gate-checked bag. If keeping the bag in the cabin matters to you, the practical levers are boarding earlier, buying up from Saver, or traveling lighter.

On smaller regional aircraft, expect routine valet gate-checking of standard carry-ons regardless of boarding order. It is free and the bag comes back at the aircraft door.

If your bag is oversize

A bag that fails the sizer at the gate gets checked. If it fits the published limit and the aircraft is the problem, that is free. If the bag genuinely exceeds 22 x 14 x 9, it can be charged standard checked bag fees, and you lose cabin access to everything inside it. Alaska's enforcement is not aggressive by reputation; agents eyeball rather than measure, and compliant-looking bags pass without ceremony. But eyeballing cuts both ways, and a visibly overstuffed bag invites the sizer. The reliable strategy is a bag that fits the published number with wheels and handles counted. Our carry-on size guide explains how to measure properly and compares every US airline's limits.

How Alaska compares to the other majors

Alaska sits on the industry standard alongside Delta, American, United, and JetBlue, all at 22 x 14 x 9 with wheels and handles included. Southwest allows a larger 24 x 16 x 10 bag. A carry-on sized to the 22 x 14 x 9 standard clears every major US airline, which is the sane way to buy luggage if your travel is not confined to a single carrier.

Common questions

Does Alaska's Saver fare include a carry-on?

Yes. Every Alaska fare, Saver included, comes with a full-size carry-on and a personal item. Saver's restrictions concern boarding order, seat assignment, and changes, not cabin baggage. Confirm your fare's inclusions at booking, since fare rules get revised.

Do wheels and handles count toward Alaska's limit?

Yes. The 22 x 14 x 9 limit describes the bag's full exterior, wheels and handles included. Measure from the floor to the highest point with the telescoping handle down.

Does Alaska weigh carry-on bags?

Not on domestic flights; no weight limit is published. The requirement is that you can lift the bag into the bin yourself. Partner airlines on international itineraries may enforce weight caps, so check each carrier on the route.

What happens if the bins are full when I board?

Alaska gate-checks remaining roller bags free of charge and you collect the bag at baggage claim or the aircraft door. Keep medication, electronics, and spare lithium batteries in your personal item, since spare batteries can never ride in a checked or gate-checked bag.

Is Alaska strict about carry-on size?

Enforcement is moderate. Agents eyeball bags rather than measure them, and bags that look compliant pass without comment. A visibly oversized or bulging bag gets sent to the sizer, and a bag that fails it gets checked.

A carry-on built for Alaska's sizer

The TALO Cabin is built to standard cabin sizing for the major US airlines, with the wheels and the machined telescoping handle inside the envelope the sizer measures, so the case you roll to an Alaska gate is the case that fits, on Alaska and on every other 22 x 14 x 9 carrier. Exact dimensions are listed on the product page. See The Cabin for the full details, and compare allowances across carriers in our carry-on size guide.
