Latest News About Alaska Airlines Carry On Size

Updated 2026-04-21 21:03

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]
