If you have the question that can bring a purse and a backpack on Alaska Airlines then you should know that if it can fit under the seat, Alaska Airlines' backpack is regarded as a personal item. You are usually allowed to bring carry-on luggage and personal bags. They do not, however, treat each and every one of the bags as a separate object. They can be a briefcase, tote bag or laptop bag. However, they rarely include "backpack" in those listings.
No, a backpack is not counted as a personal item on Alaska Airlines as Alaska Airlines allows passengers to check one bag of carry-on luggage (estimated size: 22" x 14" x 9" or 45 of straight inches, handles, and wheels) and one small personal bag such as a handbag, briefcase, or laptop bag for free.
