Alaska Airlines Carry-On Rules: Size, Personal Item & Baggage

Alaska Airlines carry-on dimensions

• Carry-on: 22 × 14 × 9 inches, including wheels and handles.
• Personal item: one smaller item such as a purse, briefcase or laptop bag.
• Linear size: 45 inches total across length, width and height.

Before boarding

Measure after packing, especially if the bag expands. Alaska’s size includes external parts, so shell measurements alone can mislead. Smaller aircraft and full flights can still require gate checking.

Pack for the tightest itinerary rule

For a multi-airline trip, follow the strictest carrier. A 22 × 14 × 9 carry-on paired with a compact personal-item bag is a flexible starting point.

Verify through Alaska’s official carry-on guidance before travel.
