Alaska Airlines allows a carry-on up to 22 x 14 x 9 in, measured including wheels and handles. Put your own bag's measurements in below — it opens with Alaska Airlines's own limit filled in.
| Carry-on maximum | 22 x 14 x 9 in (including wheels and handles) |
| Personal item | No numeric size published — it must fit under the seat |
| Cabin weight limit | None published |
| Is the carry-on free? | Yes, included with your fare |
| If it does not fit | Must fit the overhead bin or under the seat; otherwise it is checked. |
Alaska publishes BOTH a per-side limit of 22 x 14 x 9 in and a 45 linear-inch cap, explicitly including wheels and handles, and applies it across all aircraft types.
Alaska Airlines's 22 x 14 x 9 in works out to about 2772 cubic inches (45.4 litres) of cabin allowance, which ranks 17 of 22 among the airlines we have verified, about 7% less than the median carrier.
The same 22 x 14 x 9 in limit is used by 6 other airlines here — American Airlines, Delta Air Lines, United Airlines, JetBlue and others. A bag bought to that spec travels widely, which is exactly why it is the size most luggage is sold in.
13 of the airlines we track allow a larger bag and 2 allow less, so a bag sized to Alaska Airlines clears roughly 14% of the carriers here.
Common bag sizes measured against Alaska Airlines's published limit, including its 45-inch cap on length plus width plus height. Every figure includes wheels and handles, which is where most bags lose.
| Bag | Size | On Alaska Airlines | Why it matters |
|---|---|---|---|
| Cabin-max spinner | 22 × 14 × 9 in | Only just — 0 in spare | The standard US carry-on, sold as “22-inch” |
| Compact 21-inch | 21 × 14 × 9 in | Only just — 0 in spare | A common step down |
| European cabin bag | 21.7 × 15.7 × 7.9 in | Over the linear cap | Sized to 55 x 40 x 20 cm |
| Underseat tote | 17 × 13 × 8 in | Fits, 1 in spare | Typical personal-item size |
| Oversized “carry-on” | 24 × 16 × 10 in | Over the linear cap | Sold as carry-on, larger than most limits |
If it does not fit, the bag gets checked — and on Alaska Airlines a first checked bag costs $45 each way, with another $100 if it is over 50 lb. On a return trip that is $90 for a bag you meant to carry on.
Alaska Airlines does not publish a numeric personal-item size — the rule is simply that it fits under the seat in front of you. Any exact figure you find quoted elsewhere is someone's inference rather than Alaska Airlines's stated limit, which is why we do not repeat one.

No — a full-size carry-on is included with your fare, alongside a personal item.
Must fit the overhead bin or under the seat; otherwise it is checked.
Alaska Airlines publishes no cabin weight limit for the main carry-on on most fares, though staff can still refuse a bag you cannot lift into the locker yourself.
Alaska publishes NO numeric personal-item size — the page says 'one small personal item such as a purse, briefcase, or laptop bag'. At least one of your two items must go under the seat in front of you.
Yes. Alaska Airlines measures the bag including wheels, handles and any external pockets, which is why a bag sold as “22 inch” can still measure over.
