I don’t have live access to the latest news right now, but here’s the most recent, generally applicable info on Alaska Airlines’ carry-on size that’s commonly referenced.
- Typical maximum carry-on size: 22 x 14 x 9 inches (56 x 36 x 23 cm), with a total of 45 linear inches. This is the standard you’ll see cited in recent guidance and is the size most travelers are expected to meet for cabin baggage. [cite ][cite ]
- Personal item: In addition to the carry-on, you are usually allowed a personal item (like a purse, laptop bag, or small backpack) that must fit under the seat in front of you. Size limits for personal items are typically smaller and vary by aircraft, so check your specific flight if you’re close to the limit. [cite ]
- Rationale: The change was driven by space efficiency and consistency with many other U.S. and international carriers, to reduce conflicts during boarding and connections. [cite ][cite ]
