Latest News About Alaska Airlines Carry On Size

Direct answer: Alaska Airlines’ carry-on size policy has been 22 x 14 x 9 inches since June 4, 2018, with one carry-on bag and one personal item allowed on board. For the latest news, there hasn’t been a widely reported change to this policy since then, but specs can vary by partner airlines (Horizon/ SkyWest) and by itinerary, so always verify on Alaska’s official baggage page before your trip.[2][5][7][9]

What to check before you fly

• Policy details: Maximum carry-on dimensions (22" x 14" x 9") and the one-bag-plus-one-item rule, plus any weight limits if applicable. Alaska’s official pages are the most reliable source for current numbers.[5]
• Flight partners: If you’re connecting with Horizon or SkyWest, confirm their baggage allowances as they align with Alaska’s published rules.[5]
• Exceptions: Certain items (musical instruments, delicate equipment, etc.) may have special handling; review the exceptions on Alaska’s baggage info page.[5]

Illustrative note

• If you’ve flown Alaska on a multi-leg journey, you’ve likely encountered the standard 22" x 14" x 9" rule, which was introduced to improve overhead bin space and consistency across itineraries.[5]
