Alaska Airlines baggage allowance
What a Alaska Airlines First Class fare includes, what changes it, and where to check Alaska Airlines's current fees.
Last updated · Reviewed by Editorial Team
A standard Alaska Airlines First Class fare on Alaska Airlines includes 1 × 23kg checked (free). That is the figure worth planning around, and for most agency-issued premium tickets it is what you will get.
It is indicative, not a guarantee. Alaska Airlines sells business class as a family of branded fares, and the cheapest brand in the family can include one checked bag where the flexible brand includes two — same seat, thinner entitlement. Your allowance comes from the fare brand you bought, not from the cabin. The carrier’s own page, linked below, is the authority for your ticket.

How it works
Alaska Airlines allows a single checked piece
Alaska Airlines includes one checked bag of up to 23kg on a standard Alaska Airlines First Class fare. A second bag is an extra-baggage purchase rather than something the fare covers, so splitting your packing across two cases does not help — the second is chargeable whatever it weighs. The 23kg cap applies to the one bag on its own, and buying additional allowance online before you travel is materially cheaper than buying it at the airport.
Variables
Five things that change what you actually get
- Fare brand. The single biggest variable on Alaska Airlines, and the one most travellers never check. The entry-level business brand can carry half the checked allowance of the flexible brand at the same seat.
- Per-bag weight, not total weight. Alaska Airlines caps each piece at 23kg — going over on one bag is charged even when your bags together are under the combined allowance.
- Elite status and co-branded cards. These stack on top of the fare allowance and often extend to partner-operated segments, which the carrier's baggage page will state but your fare rules will not.
- Operating carrier. On a oneworld itinerary the metal flying each segment can determine the rule applied at check-in — alliance membership does not pool allowances.
- Route and direction. Allowances on the same carrier can differ between regions, and occasionally between outbound and return, where different filed fares apply in each direction.
By cabin
What Alaska Airlines includes as you move up
Economy
Typically one checked bag, and on the cheapest fare brands sometimes none at all — basic-economy products strip checked baggage and sell it back at booking or check-in. This is the cabin where the fee schedule does the most work.
Premium economy
Usually a second checked bag appears here, often at a lower per-bag weight than Alaska Airlines First Class gets. The cabin allowance tends to improve before the checked allowance does.
Alaska Airlines First Class
1 × 23kg checked (free) on a standard fare, plus priority tags that get your bags off the belt first. On routes where economy pays for a second bag, that entitlement alone is worth a meaningful slice of the premium.
Fees
What Alaska Airlines charges beyond the allowance
We publish no fee figures for Alaska Airlines, and that is a deliberate limit on what this page claims rather than an omission. Excess-weight, oversize and additional-bag pricing moves several times a year and varies by route, fare brand, status tier and purchase channel. A number mirrored here would begin decaying the day it was written, and the place a stale baggage fee surfaces is the check-in desk.
Two things hold regardless of the current price: buying extra allowance online before you travel is materially cheaper than buying it at the airport, and paying for an additional bag is very often cheaper than paying overweight on a bag you already have.
