What is worth knowing about Alaska Airlines
Alaska is explicit about the thing most carriers leave to the gate agent: measure with wheels, handles and expandable pockets included, not the flat body of the case. Its personal item goes the other way and has no published dimensions at all — the rule is "one smaller personal item" that fits under the seat, so the under-seat space is the only measurement that counts. Checked bags follow the US standard of 62 linear inches and 50 lb before oversize and overweight charges start.
Two limits Alaska Airlines does not set
The sizes above are the ones Alaska Airlines publishes. These are not, and they do not change when you switch carriers: liquids in the cabin — at a US checkpoint every liquid, aerosol, gel, cream and paste must be 3.4 oz (100 ml) or less and fit one quart-sized bag (TSA — Liquids, Aerosols and Gels Rule); and power banks and spare lithium batteries, which must be carried in the cabin only, never in a checked bag, with an ordinary rechargeable cell capped at 100 watt-hours (FAA PackSafe — Lithium Batteries). The FAA states that airlines may set stricter watt-hour and quantity limits than its own, so Alaska Airlines can be tighter than this and never looser.
