As of May 1, 2009, Alaska Airlines and its partner, Horizon Air, have begun a series of new policies regarding baggage. In addition, they have a few stipulations concerning luggage that are more restrictive than other carriers.
Alaska Airlines and Horizon Air allow one carry-on bag, which can measure up to 10 inches high by 17 inches wide by 24 inches long (25 by 43 by 61 cm) including wheels and handles, and one personal item. Additional items must be checked, for a fee of $25 (prices as of October 2009).
Alaska Airlines now charges $15 for the first checked bag, $25 for the second and $50 for the third. These fees are one way and are in addition to any surcharges that may be added for exceeding weight or size restrictions.
Checked Baggage Restrictions
Each checked bag should weigh no more than 50 pounds and be no larger than 62 linear inches. Bags exceeding this, either in weight or size, will incur additional charges.
Exceeding the weight or size allowance will cost extra for a passenger. Bags between 51 and 100 lbs. cost an additional $50 each way. Each bag between 63 and 80 inches costs $50 each way, while one between 81 and 115 inches costs $75.
For those traveling with military orders, luggage may weigh up to 70 lbs. without additional charges. Those traveling with strollers, car seats, wheelchairs or select sporting equipment will not be charged excess fees. Passengers connecting to international flights may be allowed to follow the baggage allowance and weight restrictions of the international airline.
