Alaska Airlines allowance at a glance
| Bag | Maximum size | Maximum weight | Notes |
|---|---|---|---|
| Carry-on | 22x14x9 in56x36x23 cm | No stated limit | Alaska and Hawaiian now publish one joint baggage policy following their merger, and this size is the figure given on that shared page. Alaska blocks automated reading of its site, so the checked allowance and fees on this record are not yet confirmed against the carrier. |
This page goes deeper on one part of the policy. The full record is at Alaska Airlines Baggage Rules.
Alaska Airlines does not publish a carry-on weight limit at all. Its own baggage page describes the bag only by its box. The Alaska Airlines carry-on size limit is 22 x 14 x 9 inches, wheels and handle included.
It now covers Hawaiian too, since the two airlines merged their baggage policy.
That single box covers both brands now. A bag that clears the Alaska sizer clears the Hawaiian one too. Measure it once against the wheels and handle, not just the shell, and you are done for either carrier.
How strictly the gate actually checks it
Traveler reports describe enforcement that depends on the agent working the gate that day. Several frequent flyers say they have never been asked to use a sizer at all. Others describe being waved toward one on a full flight.
That usually happens late in boarding, once bin space has run out.
When a bag does get flagged, the common outcome is a free gate check, not a fee. A bag that fails the sizer at the door tends to go in the hold at no extra cost. That is a real difference from carriers that bill on the spot for an oversized bag.
None of that is a promise, though. A packed flight with a strict agent is the scenario where a borderline bag gets stopped. Pack as if the box is real.
What each fare actually buys you
Saver, Alaska’s cheapest published fare, still includes a full carry-on and a personal item. That sets it apart from the basic economy tiers other US carriers sell. There is a catch, though.
Saver passengers board in the last group. On a full flight, the bins near the front fill up before they get on. The bag itself meets the same carry-on size limit as any other fare.
The practical result is a longer walk to find bin space. Or it is a higher chance of a gate check simply because the bins filled first. Readers coming from an airline with a true personal item only basic fare should not assume Alaska works the same way.
Alaska Airlines carry-on size rules do not shrink on Saver. The full box still applies, and Alaska does not strip the carry-on from any published fare class.
The personal item and a failed bag
Alaska describes a personal item, such as a purse, briefcase or laptop bag, as part of every fare. That comes alongside the carry-on, not instead of it. What its pages do not do, at least on what could be confirmed here, is publish a specific box in inches for that personal item.
Readers who want a hard number will not find one there. The rule of thumb still applies: it needs to fit under the seat in front of you. Gate agents judge that by eye more often than with a sizer.
If your carry-on gets pulled at the gate, the personal item stays with you while the rolling bag goes to the hold. Pack medication, a charger and anything fragile in that second bag, not the one that might get gate checked. Alaska publishes no carry-on weight limit, which matches most US domestic carriers.
Bags that fit the box
The Samsonite Omni PC 20 inch hardside spinner is the most reviewed carry-on on Amazon. Samsonite lists its own overall size at about 22 x 15 x 9.8 inches with the wheels on. That runs a touch past 14 and 9 inches on paper.
Most buyers report it clears sizers anyway. But a borderline gate on a full flight is where that fraction of an inch could matter.
The Travelpro Maxlite 5 21 inch softside carry-on spinner measures close to the box when zipped down. Its expansion zip adds roughly two inches of depth. Travelpro’s own guidance is to board it unexpanded on any strict airline.
Anyone carrying camera gear toward Alaska’s outdoor routes wants something sturdier. Think Anchorage, Juneau or Kona. The Pelican 1510 carry-on case is built to the same 22 x 14 x 9 inch box, with foam cut to hold gear in place.
It is one of the few hard cases sized to Alaska Airlines carry-on size limits exactly, rather than close to them.
For a bag meant to survive years of Alaska routes, the Briggs and Riley Baseline Essential 22 inch carry on spinner carries an unconditional lifetime guarantee that covers airline damage. That matters most on a case that gets gate checked now and then.
| Bag | Maker’s overall size | Against the 22 x 14 x 9 in box |
|---|---|---|
| Samsonite Omni PC 20 in | 22 x 15 x 9.8 in | Over on width and depth per spec sheet, but commonly clears sizers |
| Travelpro Maxlite 5 21 in | 23 x 14.5 x 9 in unexpanded | Board it unexpanded; expanded runs past the box |
| Pelican 1510 | 22 x 14 x 9 in | Built to the exact box |
| Briggs and Riley Baseline Essential 22 in | Compression design, carry on class | Sized for the box; guarantee covers gate check damage |
Whatever you pack, a bag that already clears a tighter international carry-on size chart will clear this box without a second thought. It is the 22 inch bags at the edge, not the small ones, worth measuring before the gate.
The bottom line
The Alaska Airlines carry-on size comes down to one shared 22 x 14 x 9 inch box for Alaska and Hawaiian, no published weight limit, and a sizer that gate agents use unevenly. A failed bag usually means a free gate check, not a fee, which is milder than several rivals. Compare the numbers against Southwest’s carry-on record or Delta’s if your trip could shift carriers, and measure the bag once with a size checker rather than trust the sizer to be there.
Common questions
Does Alaska Airlines weigh carry-on bags?
Alaska’s own baggage page does not list a weight limit for carry-on bags, only the 22 x 14 x 9 inch size box, and staff generally do not put cabin bags on a scale.
Does Saver fare on Alaska Airlines include a carry-on bag?
Yes. Saver still includes a full carry-on and a personal item, though Saver passengers board last, so overhead bin space can run out before they get on.
What happens if my carry-on does not fit Alaska's sizer?
Travelers commonly report a free gate check rather than a fee when a bag is flagged as oversized, though this is not guaranteed on a full flight.
Does Alaska Airlines use the same carry-on rules as Hawaiian Airlines?
Yes. Since the two airlines merged their baggage policy, both carriers now publish the same 22 x 14 x 9 inch carry-on box.
What size is the personal item on Alaska Airlines?
Alaska does not publish exact inch dimensions for the personal item the way it does for the carry-on, only that it must fit under the seat in front of you.
What should I pack in my personal item in case my carry-on gets gate checked?
Keep medication, chargers and anything fragile in the personal item, since that bag stays with you if the carry-on has to go in the hold.
