Alaska and Hawaiian now publish one shared baggage policy. Since the merger, both airlines’ rules live on alaskaair.com, which is where Alaska Airlines baggage rules for either carrier now come from.
The carry-on on that shared page is 22 by 14 by 9 inches, or 56 by 36 by 23 centimeters. That is the standard US frame.
What the shared page confirms
The 22 by 14 by 9 carry-on applies across the combined network. It is the same figure used by American, Delta and United.
A bag built to that spec fits Alaska and fits everywhere else in the US market. There is no need for a carrier specific purchase.
Hawaiian’s own baggage pages now redirect or return errors. The shared page is the live source.
Why the checked allowance is blank here
Alaska blocks automated reading of most of its site. We reached the carry-on page and could not reach the checked baggage pages.
Rather than fill the gap with figures from an aggregator, this page leaves the checked allowance and fees empty. Our verification policy explains why.
A gap we tell you about is more useful than a number we cannot stand behind.
Where to get the checked figures
Your booking confirmation states the checked allowance for your specific fare and route. That is the authoritative place.
The alaskaair.com baggage section carries the fee schedule in a normal browser. It loads fine for a person, just not for an automated request.
Alaska Airlines baggage rules also vary by credit card and elite status, which a general table would not capture anyway.
What the merger changes in practice
If you booked on Hawaiian, check alaskaair.com rather than the old Hawaiian pages. The rules you are subject to are published there now.
Interisland Hawaii flights and North America flights may still carry different allowances. We could not read those separately, so we do not state them.
See our Hawaiian Airlines page for the same position from the other side of the merger.
How Alaska Airlines baggage rules compare
At 22 by 14 by 9, Alaska matches Delta, American and United exactly. Nothing unusual to plan around.
It is smaller than Frontier, which allows 24 by 16 by 10. Frontier is the outlier, not Alaska.
A standard US carry-on is the right purchase for this network.
The bottom line
Alaska Airlines baggage rules are conventional on the cabin side and, for now, unreadable on the checked side. We publish the first and decline to guess at the second.
Confirm the carry-on in the size checker, and read your checked allowance in your own booking.
