Why there is no number

Alaska Airlines is one of 6 airlines in our set that publish no personal-item dimensions. The rule is functional rather than numeric: the bag has to fit fully under the seat in front of you, and cabin crew judge it by whether it does.

Figures for Alaska Airlines circulate widely anyway. They come from measuring the under-seat space on particular aircraft, or from copying another airline's published limit — neither is Alaska Airlines's rule, and neither binds the person at the gate. We publish the absence instead, because a traveller who buys a bag to an invented number and is charged for it has been misled by the number, not by the airline.

In practice the under-seat space on a narrowbody is roughly 17 to 19 inches wide and 9 to 11 inches high, and it shrinks where a seat has a lifejacket box or an entertainment unit beneath it. A soft bag that squashes is worth far more than an exact measurement here.

Personal item vs carry-on on Alaska Airlines

Both bags are included in the fare on Alaska Airlines, so the personal item is an addition to your 22 x 14 x 9 in carry-on rather than a replacement for it. The two limits are judged separately — a bag that is too big for under the seat may still be fine overhead.

How Alaska Airlines enforces it

Alaska Airlines publishes no cabin weight limit, so in practice the personal item is judged on whether it fits the space rather than what it weighs. You still have to be able to handle it yourself.

Must fit the overhead bin or under the seat; otherwise it is checked. An over-large personal item usually travels overhead instead, which is free on Alaska Airlines and therefore a much softer landing than on a carrier that charges for the carry-on.

Two practical notes that apply on any airline: the under-seat space is smaller in a row with a lifejacket box or an entertainment unit beneath the seat, and a soft bag that compresses will pass where a rigid case of identical stated dimensions will not. Measure with anything strapped to the outside included.
