Passengers may carry one personal item and one carry-on into the passenger cabin. The personal item, such as a purse, briefcase or laptop, must fit under the seat in front of the traveler. The carry-on must measure no more than 10 inches high by 17 inches wide by 24 inches long. At the discretion of the gate agent, carry-on items that meet all requirements may need to be checked in if there is no more available space.
Items that do not count as a carry-on but may still be brought on board include coats, hats, umbrellas, reading material, child restraint seats when occupied by a child, strollers, medical assistant devices such as wheelchairs, food for immediate consumption, pillows and service items. Prohibited items include liquids, gels or aerosols exceeding 3.4 ounces or 100 ml, alcohol, flammable liquids or solids, pressurized containers, weapons and sharp objects.
All checked bags incur a separate charge but must not exceed 50 pounds or a combined length, height and width of 62 inches. Luggage going over these limits are subject to oversize and overweight fees. Some passengers are exempt from being charged for the first two bags, including first-class passengers, mileage plan MVP and MVP Gold members, those traveling to/from Guadalajara, Mexico, and Mexico City, those traveling wholly within Alaska, and military personnel on orders. Items exempt from checked baggage charges include strollers, wheelchairs and luggage for those making international connections.
Items prohibited from checked baggage include internal combustion engines, explosives, corrosive solids and liquids, pressurized containers, matches and lighters, lithium batteries and Styrofoam containers.
Sporting goods are treated with special regulations. For example, equipment that incur standard fees with oversize and overweight charges include bicycles, kayaks, surfboards, bowling equipment and skateboards. Equipment that may exceed the size restrictions for free (up to 115 inches) but not the weight regulations include golf clubs and skis/snowboards.
Many of the rules for firearms are governed by TSA and cover sports rifles, shotguns, handguns, starter pistols, BB guns, flare pistols and antique firearms. Such weapons can be included in the baggage allowance if unloaded and suitably packed for transport. Ammunition must be packed in a separate, durable container. Both firearms and ammo must be declared at check-in, so the passenger can read and sign a special tag for each. (REFERENCE 4)
